Subtraction Within 10 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. take
2. fewer
3. minus
4. left
5. less
6. away
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 6 - 3 = 3
6 breaks into two equal groups of 3. Take one group of 3 out and exactly 3 are left.
2. 8 - 5 = 3
You know 5 + 3 = 8, so going the other way, 8 - 5 must equal 3.
3. 10 - 4 = 6
Think of 10 as 4 and 6. When you take the 4 away, the 6 is what stays.
4. 9 - 7 = 2
7 is just 2 away from 9. Take that 7 off and only 2 steps are left to reach zero.
Part C: True or False?
Read each statement. Circle True or False.
1. 7 - 2 = 5
True False
True — 5 and 2 put together make 7, so taking the 2 away leaves 5. The subtraction works.
2. 10 - 3 = 8
True False
False — from 10, hop back three: 9, 8, 7. You actually land on 7, not 8.
3. 6 - 6 = 0
True False
True — when the number you subtract is the same as what you started with, the group is emptied all the way to 0.
