Let’s solve each of the four word problems step by step, using place value (Tens and Ones) as shown in the worksheet.

🔺 Problem 1: Cassy has 23 red ribbons and 14 green ribbons. How many ribbons does she have in all?
This is an
addition problem:
23 + 14 = ?
Break it down by place value:
-
Tens: 2 tens + 1 ten =
3 tens
-
Ones: 3 ones + 4 ones =
7 ones
So,
23 + 14 = 37
✔ Answer: 37 ribbons
> In the grid:
> - Tens column: write
3
> - Ones column: write
7
> - Bottom box (total):
37

⭐ Problem 2: There are 35 bugs on a leaf. 10 more joined them. How many bugs are there altogether?
This is also
addition:
35 + 10 = ?
Break it down:
-
Tens: 3 tens + 1 ten =
4 tens
-
Ones: 5 ones + 0 ones =
5 ones
So,
35 + 10 = 45
✔ Answer: 45 bugs
> In the grid:
> - Tens column: write
4
> - Ones column: write
5
> - Bottom box (total):
45

🟥 Problem 3: Cassy has 44 ribbons. She gives 23 away. How many ribbons does she have left?
This is a
subtraction problem:
44 – 23 = ?
Break it down:
-
Tens: 4 tens – 2 tens =
2 tens
-
Ones: 4 ones – 3 ones =
1 one
So,
44 – 23 = 21
✔ Answer: 21 ribbons left
> In the grid:
> - Tens column: write
2
> - Ones column: write
1
> - Bottom box (difference):
21

⭐ Problem 4: There are 76 bugs on a leaf. 35 bugs fly away. How many bugs are left?
This is
subtraction:
76 – 35 = ?
Break it down:
-
Tens: 7 tens – 3 tens =
4 tens
-
Ones: 6 ones – 5 ones =
1 one
So,
76 – 35 = 41
✔ Answer: 41 bugs left
> In the grid:
> - Tens column: write
4
> - Ones column: write
1
> - Bottom box (difference):
41

✔ Final Answers Summary:
| Problem | Operation | Answer |
|---------|-----------|--------|
| 1 | Addition | 37 |
| 2 | Addition | 45 |
| 3 | Subtraction | 21 |
| 4 | Subtraction | 41 |
You can now fill in each grid with the correct digits in the Tens and Ones columns, and write the total/difference in the bottom box.
