Addition & Subtraction Word Problems Within 20 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. total
2. minus
3. solve
4. plus
5. left
6. fewer
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Sam has 8 stickers. He gives away 5. How many left? 3
Giving away means we subtract: 8 - 5 = 3 stickers left with Sam.
2. There are 6 frogs. 7 more hop in. How many now? 13
More frogs hop in, so we add the two groups: 6 + 7 = 13 frogs now.
3. A plate has 12 grapes. You eat 4. How many remain? 8
Eating grapes takes them away, so we subtract: 12 - 4 = 8 grapes remain.
4. Lily picks 9 flowers. She picks 5 more. How many total? 14
Lily picks more flowers, so we add both groups: 9 + 5 = 14 flowers total.
Part C: True or False?
Read each statement. Circle True or False.
1. 15 - 8 = 7
True False
True. Count back 8 from 15: 14, 13, 12, 11, 10, 9, 8, 7. So 15 - 8 does equal 7.
2. 7 + 6 = 12
True False
False. 7 + 6 = 13, not 12. Count on 6 from 7: 8, 9, 10, 11, 12, 13.
3. 11 - 3 = 8
True False
True. Count back 3 from 11: 10, 9, 8. So 11 - 3 does equal 8.
