Room Mom 101: Teaching Place Value - Free Printable

Let’s go row by row and fill in the chart for the number 42 first, then move to the other numbers.

---

First Row: Number = 42

We need to write it in 4 ways:

#### 1. Words:
42 is “forty-two” → so we break it into tens and ones:
→ 4 tens 2 ones

#### 2. Expanded Form:
42 = 40 + 2
So: 40 + 2 = 42

#### 3. Picture:
Already given — there are 4 groups of ten sticks (each group has 10) and 2 single sticks → that’s 42.

---

Second Row: Still for 42? Wait — looking at the chart, each row seems to be a different way or maybe a different number? Let me check again.

Actually, looking closely — the first big box says “Number: 42”, and then below that, there are multiple rows under it. But then later there’s “2 tens 4 ones” and “78” and “8 tens 3 ones”. So probably each row is a separate problem.

Wait — let me re-read the instruction:

> Fill in the chart with the different ways to write each number.

And the columns are: Number | Words | Expanded Form | Picture

But in the table, some rows have “Number” filled (like 42, 78), others have words like “___ tens ___ ones” or “2 tens 4 ones”.

Ah — I think the table is structured so that each row represents one number, and you have to fill in all four columns for that row.

Let’s list out each row as a separate number to solve:

---

## Row 1: Number = 42

- Words: 4 tens 2 ones
- Expanded Form: 40 + 2 = 42
- Picture: Already drawn (4 bundles of 10, 2 singles)

✔ Done.

---

## Row 2: Words = “___ tens ___ ones” — but no number given? Wait, look — actually, this might be another representation of 42? Or maybe it's blank for us to choose? No — looking again, perhaps each row corresponds to the same number? That doesn’t make sense because later we see “2 tens 4 ones” which is 24, and “78”, etc.

Wait — let me count the rows:

There are 6 rows total.

Row 1: Number = 42 → we did that.

Row 2: Blank number, blank words, expanded form blank, picture blank → but above it, the header says “Fill in the chart with the different ways to write each number.” And the first number is 42. Maybe all rows under 42 are different representations of 42? But then why is there “2 tens 4 ones” later? That’s 24.

Looking more carefully — actually, the table has:

- First cell: “Number” column has “42” in bold, spanning multiple rows? No — in the image, “42” is only in the first row of the “Number” column. Then next row in “Number” column is empty, then “2 tens 4 ones” is in the “Words” column? Wait no — let me reconstruct based on standard worksheets.

Actually, from common worksheet design, each row is a separate number to represent in 4 ways.

So let’s treat each row independently:

---

## Row 1:
Number: 42

Words: 4 tens 2 ones

Expanded Form: 40 + 2 = 42

Picture: Given (4 tens, 2 ones)

---

## Row 2:
Number: ? → Not given. But Words column says “___ tens ___ ones” — that’s not helpful. Wait — perhaps this row is meant to be another way to write 42? But that would be redundant.

Wait — looking at the third row: Expanded Form says “50 • 9 = ___” — that looks like a typo? Probably meant “50 + 9 = ___” → which is 59.

Similarly, fourth row: Words = “2 tens 4 ones” → that’s 24.

Fifth row: Picture shows 7 tens and 8 ones? Wait no — fifth row picture: let’s count — there are 7 long bars (each = 10) and 8 small squares → so 78.

Sixth row: Number = 78

Seventh row: Words = “8 tens 3 ones” → 83

Wait — now I’m confused about how many rows there are.

Let me count the rows in the table as shown:

From top to bottom after headers:

1. Number: 42 → Words: ___ tens ___ ones → Exp: _+_=_ → Pic: given

2. Number: (blank) → Words: ___ tens ___ ones → Exp: (blank) → Pic: (blank)

3. Number: (blank) → Words: ___ tens ___ ones → Exp: 50 • 9 = ___ → Pic: (blank) [probably 50+9=59]

4. Number: (blank) → Words: 2 tens 4 ones → Exp: _+_=_ → Pic: (blank)

5. Number: (blank) → Words: ___ tens ___ ones → Exp: _+_=_ → Pic: 7 tens and 8 ones? Wait — in row 5, picture column has 7 longs and 8 dots → so 78

6. Number: 78 → Words: ___ tens ___ ones → Exp: _+_=_ → Pic: (blank)

7. Number: (blank) → Words: 8 tens 3 ones → Exp: _+_=_ → Pic: (blank)

That’s 7 rows? But in the original image description, it might be 6. To avoid confusion, let’s assume each row is a separate number, and we’ll solve based on what’s given in each row.

Perhaps the “Number” column only has entries where the number is given numerically, and otherwise we derive from other columns.

Let’s go row by row as presented in typical such worksheets:

---

I think the safest approach is to consider that each row represents a number, and we fill all columns for that row based on whatever is given.

Let’s define each row:

---

Row A:
Given: Number = 42
→ Words: 4 tens 2 ones
→ Expanded: 40 + 2 = 42
→ Picture: already shown (4 tens, 2 ones)

Row B:
Given: Nothing explicitly, but likely continues 42? Unlikely. Perhaps it's a mistake. Looking at common versions of this worksheet, often the first few rows are for 42, then new numbers.

Wait — in the user's image description, it says:

"Fill in the chart with the different ways to write each number."

And the first number is 42, then later 78, and also "2 tens 4 ones", "8 tens 3 ones", and "50 • 9" which is probably 50+9=59.

Also, in row 5, picture shows 7 tens and 8 ones → 78.

So let's list the numbers we need to handle:

1. 42
2. 59 (from 50+9)
3. 24 (from 2 tens 4 ones)
4. 78 (from picture or given)
5. 83 (from 8 tens 3 ones)

And possibly another row for 42 again? But that seems redundant.

Perhaps the table has 6 rows, each for a different representation, but the numbers are:

- Row 1: 42
- Row 2: ? — maybe left for student to choose? Unlikely.
- Row 3: 59 (since 50+9=59)
- Row 4: 24 (2 tens 4 ones)
- Row 5: 78 (picture shows 7 tens 8 ones)
- Row 6: 78 again? Or 83?

In row 6, Number is 78, so that's clear.

Then row 7: 8 tens 3 ones = 83.

But to match the structure, let's assume there are 6 rows, and the numbers are:

1. 42
2. [perhaps another way for 42, but let's skip and do given ones]
Actually, upon second thought, in many such worksheets, the "Number" column has the numeral, and other columns have representations, but here some rows have words or expanded form given.

To resolve this, I'll solve for each unique number mentioned:

Numbers to solve for: 42, 59, 24, 78, 83

And for each, fill all four columns.

But the table has specific rows, so let's map:

Assume the rows are:

Row 1: Number = 42 → fill Words, Exp, Pic (Pic given)

Row 2: Words = "___ tens ___ ones" — but no info, so perhaps it's for 42 again? Or maybe it's a general row. This is ambiguous.

Looking back at the user's input: "Fill in the chart with the different ways to write each number." and the chart has "Number" column with 42 and 78 specified, and other rows have partial info.

Perhaps the intended interpretation is:

- For the row with Number=42, fill the other columns.
- For the row with Words="2 tens 4 ones", fill Number, Exp, Pic.
- For the row with Exp="50 • 9 = __", assume it's 50+9=59, fill Number, Words, Pic.
- For the row with Picture showing 7 tens and 8 ones, that's 78, fill Number, Words, Exp.
- For the row with Number=78, fill Words, Exp, Pic.
- For the row with Words="8 tens 3 ones", fill Number, Exp, Pic.

And the first row after 42 might be a duplicate or error, but to be practical, let's solve for the following numbers based on what's given in each row:

Let's define 6 rows as per common layout:

Row 1:
Number: 42
Words: 4 tens 2 ones
Expanded: 40 + 2 = 42
Picture: given (4 tens, 2 ones)

Row 2:
This row has nothing given except blanks. Perhaps it's for students to create their own, but since the instruction is to fill for "each number", and no number is specified, maybe it's a mistake. In many worksheets, this might be for 42 again, but let's skip and come back.

Row 3:
Expanded Form: 50 • 9 = ___ → likely typo, should be 50 + 9 = 59
So Number: 59
Words: 5 tens 9 ones
Picture: draw 5 tens and 9 ones (5 bundles, 9 singles)

Row 4:
Words: 2 tens 4 ones → Number: 24
Expanded: 20 + 4 = 24
Picture: 2 tens, 4 ones

Row 5:
Picture: shows 7 tens and 8 ones (7 longs, 8 dots) → Number: 78
Words: 7 tens 8 ones
Expanded: 70 + 8 = 78

Row 6:
Number: 78
Words: 7 tens 8 ones
Expanded: 70 + 8 = 78
Picture: draw 7 tens and 8 ones (but in row 5 it's already drawn, so perhaps repeat or leave, but usually they want it filled)

Row 7:
Words: 8 tens 3 ones → Number: 83
Expanded: 80 + 3 = 83
Picture: 8 tens, 3 ones

But the table might have only 6 rows. To simplify, I'll provide answers for the numbers that are clearly indicated:

- 42
- 59 (from 50+9)
- 24 (from 2 tens 4 ones)
- 78 (from picture and given)
- 83 (from 8 tens 3 ones)

And for the row with Number=78, it's the same as above.

Now, for the very first row after 42, if it's blank, perhaps it's for 42 again, but that doesn't make sense. Another possibility: in some worksheets, the "Words" column for the first row is "4 tens 2 ones", and the next row is for a different representation, but I think it's safer to assume that each row with partial information is for a specific number.

Let's finalize by solving for each distinct number mentioned in the chart:

1. 42:
- Words: 4 tens 2 ones
- Expanded: 40 + 2 = 42
- Picture: 4 tens, 2 ones (given)

2. 59 (from "50 • 9 = __" assuming +):
- Number: 59
- Words: 5 tens 9 ones
- Expanded: 50 + 9 = 59
- Picture: 5 tens, 9 ones

3. 24 (from "2 tens 4 ones"):
- Number: 24
- Words: 2 tens 4 ones (given)
- Expanded: 20 + 4 = 24
- Picture: 2 tens, 4 ones

4. 78 (from picture in one row and number in another):
- Number: 78
- Words: 7 tens 8 ones
- Expanded: 70 + 8 = 78
- Picture: 7 tens, 8 ones

5. 83 (from "8 tens 3 ones"):
- Number: 83
- Words: 8 tens 3 ones (given)
- Expanded: 80 + 3 = 83
- Picture: 8 tens, 3 ones

For the row that has only "___ tens ___ ones" with no other info, it might be a placeholder, but since the instruction is to fill for each number, and those are the numbers present, I'll proceed.

Now, to present the answer as per the chart rows, let's assume the chart has 6 rows, and we fill them as follows:

- Row 1: Number=42 → Words: 4 tens 2 ones; Exp: 40+2=42; Pic: given
- Row 2: Let's say it's for 59, but in the chart, row 3 has the expanded form for 59. Perhaps row 2 is for 42 again? To avoid guesswork, I'll provide the solutions for the numbers that are unambiguously given.

Since the user expects the final answer, and to be accurate, I'll list the completed chart based on standard interpretation.

After careful analysis, here's how to fill each row:

Row 1 (Number: 42):
- Words: 4 tens 2 ones
- Expanded Form: 40 + 2 = 42
- Picture: already provided (4 tens, 2 ones)

Row 2: This row has no given information in any column except blanks. In many worksheets, this might be an error or for student choice, but since the task is to fill for "each number", and no number is specified, perhaps it's intended to be another representation of 42. However, to be consistent, let's assume it's for the next number. But looking at row 3, it has "50 • 9 = __", so likely row 2 is skipped or is for 42. I think it's best to move to row 3.

Row 3 (Expanded Form: 50 • 9 = __):
Assuming "•" is a typo for "+", so 50 + 9 = 59
- Number: 59
- Words: 5 tens 9 ones
- Expanded Form: 50 + 9 = 59
- Picture: draw 5 tens and 9 ones

Row 4 (Words: 2 tens 4 ones):
- Number: 24
- Words: 2 tens 4 ones (given)
- Expanded Form: 20 + 4 = 24
- Picture: draw 2 tens and 4 ones

Row 5 (Picture: 7 tens and 8 ones):
- Number: 78
- Words: 7 tens 8 ones
- Expanded Form: 70 + 8 = 78
- Picture: given (7 tens, 8 ones)

Row 6 (Number: 78):
- Number: 78 (given)
- Words: 7 tens 8 ones
- Expanded Form: 70 + 8 = 78
- Picture: draw 7 tens and 8 ones (or leave if already done, but typically fill)

Row 7 (Words: 8 tens 3 ones):
- Number: 83
- Words: 8 tens 3 ones (given)
- Expanded Form: 80 + 3 = 83
- Picture: draw 8 tens and 3 ones

But since the table might have only 6 rows, and row 6 is Number=78, row 7 might not exist. In the initial description, it's likely 6 rows.

To resolve, I'll provide the answers for the rows as per the most logical assignment:

Final decision: The chart has 6 rows, corresponding to:

1. 42
2. 59 (from expanded form in row 3, but let's assign row 2 to 59? No)

Perhaps the rows are:

- Row 1: 42
- Row 2: [blank, but perhaps for 42's word form, but it's already in row 1]
I think there's a misalignment.

Another approach: in the user's image, the "Number" column has "42" in the first row, then empty, then empty, then empty, then empty, then "78". And in the "Words" column, first row is "___ tens ___ ones", second row "___ tens ___ ones", third row "___ tens ___ ones", fourth row "2 tens 4 ones", fifth row "___ tens ___ ones", sixth row "___ tens ___ ones", seventh row "8 tens 3 ones" — but that's 7 rows.

To cut through, I'll solve for the numbers that are explicitly or implicitly given:

- When Number is 42: Words = 4 tens 2 ones, Exp = 40+2=42
- When Expanded is 50+9=59: Number=59, Words=5 tens 9 ones
- When Words are 2 tens 4 ones: Number=24, Exp=20+4=24
- When Picture shows 7 tens 8 ones: Number=78, Words=7 tens 8 ones, Exp=70+8=78
- When Number is 78: same as above
- When Words are 8 tens 3 ones: Number=83, Exp=80+3=83

For the final answer, since the user wants the solution, I'll provide the filled chart as per standard completion.

After double-checking calculations:

- 4 tens 2 ones = 40 + 2 = 42 ✓
- 50 + 9 = 59 ✓
- 2 tens 4 ones = 20 + 4 = 24 ✓
- 7 tens 8 ones = 70 + 8 = 78 ✓
- 8 tens 3 ones = 80 + 3 = 83 ✓

All correct.

Now, for the response, since the options are false, I only need to provide the Final Answer, which should be the completed chart or the values.

But the instruction is to provide the final correct answer after reasoning.

Since it's a chart, I'll list the answers for each row as per the most reasonable interpretation.

Assume the chart has 6 rows, and we fill them as:

Row 1: Number=42
- Words: 4 tens 2 ones
- Expanded: 40 + 2 = 42
- Picture: given

Row 2: Let's say it's for 59, but in the chart, the expanded form for 59 is in a later row. Perhaps row 2 is for the word form of 42, but it's already done.

I recall that in some versions of this worksheet, the first few rows are for the same number, but here it's mixed.

To be practical, I'll provide the answers for the numbers that are clearly defined in the chart:

For the row with "50 • 9 = __", it's 59, so:
- Number: 59
- Words: 5 tens 9 ones
- Expanded: 50 + 9 = 59
- Picture: 5 tens, 9 ones

For "2 tens 4 ones":
- Number: 24
- Words: 2 tens 4 ones
- Expanded: 20 + 4 = 24
- Picture: 2 tens, 4 ones

For the picture with 7 tens and 8 ones:
- Number: 78
- Words: 7 tens 8 ones
- Expanded: 70 + 8 = 78
- Picture: given

For Number=78:
- Same as above

For "8 tens 3 ones":
- Number: 83
- Words: 8 tens 3 ones
- Expanded: 80 + 3 = 83
- Picture: 8 tens, 3 ones

And for the first row with Number=42:
- Words: 4 tens 2 ones
- Expanded: 40 + 2 = 42
- Picture: given

The row with only "___ tens ___ ones" might be for 42, so we can put 4 tens 2 ones there, but it's redundant.

For the sake of completing the task, I'll assume that each row corresponds to a number, and the given information defines it, and fill accordingly.

Final Answer will be the values for each missing part.

Since the user may expect the chart filled, but in text, I'll list the completions.

After careful consideration, here is the accurate completion for each row based on standard educational practice:

- For the row where Number is 42: Words are "4 tens 2 ones", Expanded Form is "40 + 2 = 42"
- For the row where Expanded Form is "50 + 9 = 59" (correcting • to +): Number is 59, Words are "5 tens 9 ones"
- For the row where Words are "2 tens 4 ones": Number is 24, Expanded Form is "20 + 4 = 24"
- For the row where Picture shows 7 tens and 8 ones: Number is 78, Words are "7 tens 8 ones", Expanded Form is "70 + 8 = 78"
- For the row where Number is 78: Words are "7 tens 8 ones", Expanded Form is "70 + 8 = 78"
- For the row where Words are "8 tens 3 ones": Number is 83, Expanded Form is "80 + 3 = 83"

The row with only "___ tens ___ ones" and no other info is likely a mistake or for 42, so we can omit or fill as 4 tens 2 ones, but to avoid error, I'll include only the definite ones.

For the Final Answer, since the task is to solve the problem, and the problem is to fill the chart, I'll provide the key answers.

But to comply with the format, and since the options are false, I'll box the final numerical answers or the completions.

Perhaps the expected final answer is the values for the blanks.

Let's extract the specific blanks to fill:

From the chart description:

- First row (Number=42): Words: __ tens __ ones → 4, 2; Expanded: _ + _ = _ → 40 + 2 = 42
- Second row: all blank — skip or assume for 42, but let's say it's for 59? No.
- Third row: Expanded: 50 • 9 = __ → 59; so Number: 59; Words: 5 tens 9 ones
- Fourth row: Words: 2 tens 4 ones → Number: 24; Expanded: 20 + 4 = 24
- Fifth row: Picture given (7 tens 8 ones) → Number: 78; Words: 7 tens 8 ones; Expanded: 70 + 8 = 78
- Sixth row: Number: 78 → Words: 7 tens 8 ones; Expanded: 70 + 8 = 78
- Seventh row: Words: 8 tens 3 ones → Number: 83; Expanded: 80 + 3 = 83

But to match the likely 6-row chart, and since row 6 is Number=78, row 7 might not be there.

In the interest of time and accuracy, I'll provide the following as the final answer, focusing on the calculations:

The numbers and their representations are:

- 42 = 4 tens 2 ones = 40 + 2
- 59 = 5 tens 9 ones = 50 + 9
- 24 = 2 tens 4 ones = 20 + 4
- 78 = 7 tens 8 ones = 70 + 8
- 83 = 8 tens 3 ones = 80 + 3

All calculations verified.

For the Final Answer section, since it's a chart, but the instruction is to provide the final correct answer, I'll state the completed values for the blanks that require calculation.

Specifically, for the expanded form "50 • 9 = __", it is 59.

For "2 tens 4 ones", the number is 24.

For the picture with 7 tens 8 ones, the number is 78.

For "8 tens 3 ones", the number is 83.

And for 42, it's given.

So the key answers are 59, 24, 78, 83 for the respective rows.

But to be precise, let's output the final answer as the filled chart in text.

After all, the user said "solve the problem accurately", and the problem is to fill the chart.

I think the best way is to list the answers for each row as per the order.

Assume the rows are:

1. Number: 42 → Words: 4 tens 2 ones; Expanded: 40 + 2 = 42
2. [No given, but perhaps this is for the word form of 42, so same as above, but let's say it's for 59 based on next row] — no.

Upon reviewing online sources or standard worksheets, this type of chart usually has each row for a different number, and the given information varies.

For this response, I'll provide the following Final Answer as the solutions for the incomplete parts:

- For the row with Expanded Form "50 + 9 = ", the result is 59.
- For the row with Words "2 tens 4 ones", the number is 24, and Expanded Form is 20 + 4 = 24.
- For the row with Picture showing 7 tens and 8 ones, the number is 78, Words are "7 tens 8 ones", Expanded Form is 70 + 8 = 78.
- For the row with Number 78, Words are "7 tens 8 ones", Expanded Form is 70 + 8 = 78.
- For the row with Words "8 tens 3 ones", the number is 83, Expanded Form is 80 + 3 = 83.
- For the first row, with Number 42, Words are "4 tens 2 ones", Expanded Form is 40 + 2 = 42.

The row with only "___ tens ___ ones" and no other info is likely intended to be filled with 4 tens 2 ones for 42, but since it's the same as row 1, perhaps it's a duplicate.

To conclude, the critical calculations are correct, and for the Final Answer, I'll box the numerical results for the expanded form and the numbers derived.

But the instruction is to provide the final correct answer after reasoning, and since it's a chart, perhaps list the values.

I think for simplicity, the Final Answer can be the completed expanded forms and numbers.

Let's do this:

Final Answer:
- 42 = 4 tens 2 ones = 40 + 2
- 59 = 5 tens 9 ones = 50 + 9
- 24 = 2 tens 4 ones = 20 + 4
- 78 = 7 tens 8 ones = 70 + 8
- 83 = 8 tens 3 ones = 80 + 3

With the understanding that these fill the chart.

To match the format, and since the user may expect specific blanks filled, but in the absence of clear row mapping, I'll provide the above.

After verifying all:

40 + 2 = 42 ✓
50 + 9 = 59 ✓
20 + 4 = 24 ✓
70 + 8 = 78 ✓
80 + 3 = 83 ✓

All correct.

So the Final Answer is these equations and representations.

For the boxed answer, since it's multiple, I'll state it as:

The completed chart requires:
- For 42: words "4 tens 2 ones", expanded "40 + 2 = 42"
- For 59: number 59, words "5 tens 9 ones", expanded "50 + 9 = 59"
- For 24: number 24, expanded "20 + 4 = 24"
- For 78: words "7 tens 8 ones", expanded "70 + 8 = 78" (for both instances)
- For 83: number 83, expanded "80 + 3 = 83"

But to keep it concise for the Final Answer section:

Final Answer:
42 = 4 tens 2 ones = 40 + 2
59 = 5 tens 9 ones = 50 + 9
24 = 2 tens 4 ones = 20 + 4
78 = 7 tens 8 ones = 70 + 8
83 = 8 tens 3 ones = 80 + 3
