Let’s solve each word problem using
bar models (also called tape diagrams), which help visualize the parts and the whole in addition/subtraction problems.

Problem A:
> Annie had 14 apples in one basket and 10 apples in another. She ended with a total of 32 apples. How many apples did she have in the third basket?
Bar Model Idea:
Draw a long bar representing the total (32). Divide it into 3 parts: 14, 10, and ? (unknown).
Math:
Total = Part1 + Part2 + Part3
32 = 14 + 10 + ?
32 = 24 + ?
? = 32 - 24 =
8
✔ Answer: 8 apples

Problem B:
> Brooklyn grew 23 peaches on one tree and 23 peaches on another tree. How many peaches did she grow in all?
Bar Model Idea:
Two equal bars, each labeled 23. Combine them for total.
Math:
23 + 23 =
46
✔ Answer: 46 peaches
---
Problem C:
> Cam planted 13 pumpkin seeds, 12 watermelon seeds, and 4 lemon seeds. How many seeds did he plant in all?
Bar Model Idea:
Three bars: 13, 12, and 4. Add them together.
Math:
13 + 12 = 25
25 + 4 =
29
✔ Answer: 29 seeds

Problem D:
> Drake made 16 corn cobs. He ate 7 corn cobs. How many did his sister eat?
Bar Model Idea:
Total bar = 16. One part = 7 (Drake). The other part = ? (sister).
Math:
16 - 7 =
9
✔ Answer: 9 corn cobs
*(Note: This assumes only Drake and his sister ate them — implied by the question.)*
---
Problem E (partially visible):
> [She] gave her teacher a basket with 5 [apples?] and 6 bananas. How many fruit were there in all?
*(Assuming “5 apples” based on context.)*
Bar Model Idea:
Two bars: 5 and 6 → combine for total.
Math:
5 + 6 =
11
✔ Answer: 11 fruits
---
Problem F:
> Fiona made pineapple salsa using 9 pineapples, 2 cobs of corn, and 5 tomatoes. How many items did she use to make her salsa?
Bar Model Idea:
Three bars: 9, 2, and 5 → add them.
Math:
9 + 2 = 11
11 + 5 =
16
✔ Answer: 16 items

## 📌 Bar Model Tips:
- Draw a rectangle (bar) for the
total.
- Split it into sections for each
part.
- If you know the total and some parts, subtract to find the missing part.
- If you know all parts, add them to find the total.
This visual strategy helps students see the relationship between numbers and operations clearly!
