Subtraction Within 10 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. take
2. away
3. minus
4. fewer
5. left
6. less
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 8 - 5 = 3
8 - 5 = 3. If you have 8 crayons and give away 5, only 3 crayons stay with you.
2. 3 - 1 = 2
3 - 1 = 2. Take one finger down from three fingers and two fingers are still up.
3. 9 - 6 = 3
9 - 6 = 3. Count back 6 from 9: 8, 7, 6, 5, 4, 3. The answer is 3.
4. 10 - 7 = 3
10 - 7 = 3. Since 7 + 3 = 10, we know 10 take away 7 leaves 3.
Part C: True or False?
Read each statement. Circle True or False.
1. 7 - 4 = 3
True False
True. Counting back 4 from 7 lands on 3, and 3 + 4 = 7 proves the subtraction is right.
2. 5 - 1 = 3
True False
False. One less than 5 is 4, not 3, so the correct answer is 5 - 1 = 4.
3. 10 - 5 = 5
True False
True. Five and five make ten, so when you take 5 away from 10 you have 5 left.
