Addition Within 10 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. add
2. sum
3. more
4. plus
5. total
6. equal
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 3 + 4 = 7
Start at 3 and count up 4 more. You land on 7, so 3 + 4 = 7.
2. 1 + 6 = 7
Start at 5 and count up 2 more. You land on 7, so 5 + 2 = 7.
3. 5 + 2 = 7
Start at 1 and count up 8 more. You land on 9, so 1 + 8 = 9.
4. 4 + 4 = 8
Start at 6 and count up 4 more. You land on 10, so 6 + 4 = 10.
Part C: True or False?
Read each statement. Circle True or False.
1. 2 + 5 = 7
True False
True. 2 + 3 really does equal 5. You can check by counting up 3 from 2.
2. 4 + 3 = 6
True False
False. 4 + 4 equals 8, not 9. Count up 4 from 4 to check.
3. 1 + 8 = 9
True False
True. 0 + 7 really does equal 7. You can check by counting up 7 from 0.
