Step-by-step solution for: Second Grade Assessment Worksheets | edHelper.com
Here are the solutions to the problems on the worksheet, step by step.
1. Write the numbers
* nine: The number is 9.
* sixteen: The number is 16.
* twenty-three: The number is 23.
2. Circle all the ways to make 10
We need to find which addition problems equal 10.
* $5 + 5 = 10$ (Yes)
* $4 + 6 = 10$ (Yes)
* $7 + 3 = 10$ (Yes)
* $8 + 1 = 9$ (No)
* $8 + 1 = 9$ (No)
* Answer: You should circle $5+5$, $4+6$, and $7+3$.
3. Subtraction: $3 - 3$
If you have 3 items and take away 3 items, you have nothing left.
* $3 - 3 =$ 0
4. Addition: $27 + 10$
Add the ones column: $7 + 0 = 7$.
Add the tens column: $2 + 1 = 3$.
* $27 + 10 =$ 37
5. How much is this? (Coins)
There are 3 coins shown. They look like quarters (25 cents each).
* $25 + 25 + 25 = 75$
* Answer: 75 cents (or $\$0.75$)
6. Subtraction: $22 - 15$
* Look at the ones place: You cannot take 5 from 2. So, borrow 1 ten from the tens place.
* The 2 in the tens place becomes a 1. The 2 in the ones place becomes 12.
* Now subtract the ones: $12 - 5 = 7$.
* Subtract the tens: $1 - 1 = 0$.
* $22 - 15 =$ 7
7. Place Value
* 1 ten + 4 ones: This makes the number 14.
* 8 tens + 1 one: This makes the number 81.
8. Missing Numbers
The pattern counts up by ones: 4, __, __, __, 22.
Wait, looking closely at the image, it says `4, __, __, __, 22`. That is a very big jump for single blanks if it's counting by 1s. Let's re-read carefully.
Ah, usually these are simple sequences. Let's look at the spacing. It might be asking for numbers between 4 and something else, or perhaps it's two separate questions?
Let's look at the structure again: `4, __, __, __, 22`.
If it is counting by a specific interval to get from 4 to 22 in 4 steps (including the start):
$22 - 4 = 18$. There are 4 gaps. $18 / 4 = 4.5$. That doesn't work for whole numbers.
Let's look closer at the prompt layout. It might be `4, __, __, __` and then `__ , 22`? No, they are on one line.
Let's assume it's a typo in my reading or the sheet. Let's look at standard 1st/2nd grade patterns.
Maybe it is `14, __, __, __, 22`? No, it clearly starts with 4.
Maybe it is `4, 8, 12, 16, 20`? No, ends in 22.
Maybe it is `2, 4, 6...`? No.
Let's look at the previous question above it: "8 tens + 1 one = ___". The answer is 81.
The question below is `4, __, __, __, 22`.
Is it possible the last number is not 22? It looks like 22.
Is it possible the first number is not 4? It looks like 4.
Let's try counting by fives?
4, 9, 14, 19, 24. No.
Counting by twos?
4, 6, 8, 10, 12... no.
Let's reconsider the visual. Is it possible it is two separate problems?
Problem A: `4, __, __, __` (Count by 1s: 5, 6, 7)
Problem B: `__, 22` (Previous number: 21?)
But they are on the same line.
Let's look at the possibility of a typo in the worksheet itself or a specific skip-counting rule.
What if it is counting by 6s?
$4 + 6 = 10$
$10 + 6 = 16$
$16 + 6 = 22$
So the sequence would be: 4, 10, 16, 22.
There are three blanks.
Blank 1: 10
Blank 2: 16
Blank 3: (Wait, the 22 is printed).
So the blanks are between 4 and 22.
If the sequence is 4, [blank], [blank], [blank], 22.
That means there are 4 intervals.
Interval = $(22-4)/4 = 4.5$. Not an integer.
Let's look really closely at the image again.
It says: `4, __, __, __, 22`.
Actually, looking at the spacing, the "22" might be the answer to a different part? No, it's aligned.
Let's try another common pattern: Place Value decomposition? No.
Let's look at the coin problem again. 3 quarters = 75.
Let's look at the subtraction $22-15=7$.
Let's go back to the number line.
Could it be 4, 10, 16, 22?
If the blanks are just 3 slots, and the end number is 22.
If we fill in 10, 16, that's only two numbers.
The line has three underscores. `__ , __ , __`.
So we need 3 numbers between 4 and 22.
This implies 4 intervals.
As calculated, 18 divided by 4 is 4.5.
Is it possible the first number is 2?
$22 - 2 = 20$. $20 / 4 = 5$.
Sequence: 2, 7, 12, 17, 22.
Does the first digit look like a 2? It looks very much like a 4.
Is it possible the last number is 24?
$24 - 4 = 20$. $20 / 4 = 5$.
Sequence: 4, 9, 14, 19, 24.
Does the last number look like 24? It looks like 22.
Is it possible the last number is 20?
$20 - 4 = 16$. $16 / 4 = 4$.
Sequence: 4, 8, 12, 16, 20.
Does the last number look like 20? It looks like 22.
Let's assume the question is simply asking to count by 1s but there is a typo in the final number "22" (maybe it should be 8?), OR the first number is a typo.
However, in many worksheets, if the math doesn't result in whole numbers, I should look for a simpler explanation.
What if it is not a sequence?
What if it is `4` ones and `__` tens? No.
Let's look at the prompt again: `4, __, __, __, 22`.
There is a slight chance it is counting by 6s and the student is expected to realize the pattern fits mostly?
4, 10, 16, 22.
If I put 10, 16 in the first two blanks, what goes in the third?
Maybe the comma after the third blank is actually separating a new problem?
"4, __, __, __" AND "__, 22"?
If so:
4, 5, 6, 7
21, 22
This seems the most likely intended answer for a lower-grade worksheet where patterns are usually "count by 1". The layout is just confusing. It likely represents two short sequences.
Sequence 1: Start at 4, count up 3 times. -> 5, 6, 7.
Sequence 2: End at 22, count back 1 time. -> 21.
Let's provide the answers based on the clear calculations first, and note the ambiguity on the last one, but provide the most logical "count by 1" fill-in.
Final Check of Calculations:
* Nine: 9
* Sixteen: 16
* Twenty-three: 23
* Ways to make 10: $5+5$, $4+6$, $7+3$.
* $3-3 = 0$.
* $27+10 = 37$.
* Coins: 3 Quarters = 75 cents.
* $22-15 = 7$.
* 1 ten 4 ones = 14.
* 8 tens 1 one = 81.
* Sequence: Given the likelihood of simple counting, filling in 5, 6, 7 for the first part and 21 before the 22 is the safest bet for a young student, assuming the line contains two distinct small tasks.
Final Answer:
Write the numbers:
* nine: 9
* sixteen: 16
* twenty-three: 23
Circle ways to make 10:
* Circle: $5 + 5$, $4 + 6$, and $7 + 3$
Subtraction Box (Top Right):
* $3 - 3 =$ 0
Addition Box ($27 + 10$):
* $27 + 10 =$ 37
How much is this? (Coins):
* 75 cents (assuming they are quarters)
Subtraction Box ($22 - 15$):
* $22 - 15 =$ 7
Place Value:
* 1 ten + 4 ones = 14
* 8 tens + 1 one = 81
Number Pattern:
* 4, 5, 6, 7
* 21, 22
*(Note: The pattern appears to be counting by 1s. The blanks between 4 and the next section are 5, 6, 7. The blank before 22 is 21.)*
