Subtraction Within 10 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. minus
2. less
3. take
4. left
5. away
6. fewer
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 4 - 1 = 3
Imagine 4 fingers up and you put 1 down — now 3 fingers are still up, so 4 - 1 = 3.
2. 7 - 4 = 3
Hold up 7 fingers and hide 4 of them. Only 3 fingers are still showing, which is why 7 - 4 = 3.
3. 9 - 2 = 7
Start at 9 and hop backward twice: 9 → 8 → 7. You land on 7, so 9 - 2 = 7.
4. 10 - 6 = 4
Think of 10 fingers. Put 6 down and 4 are still up — that's why 10 - 6 = 4.
Part C: True or False?
Read each statement. Circle True or False.
1. 5 - 3 = 1
True False
False — hold up 5 fingers and put 3 down. You will see 2 still up, not 1. So 5 - 3 equals 2.
2. 8 - 4 = 4
True False
True — 8 splits evenly into two groups of 4. Take one group of 4 away and exactly 4 are left.
3. 10 - 10 = 0
True False
True — if you start with 10 and take all 10 away, the group is empty. An empty group has 0.
