Addition Within 10 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. equal
2. total
3. sum
4. plus
5. more
6. add
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 2 + 6 = 8
2 + 6 = 8. Swap it to 6 + 2 and count on from 6: 7, 8.
2. 4 + 3 = 7
4 + 3 = 7. Hold 4 in your head, then count three more: 5, 6, 7.
3. 5 + 5 = 10
5 + 5 = 10. Both of your hands have 5 fingers — put them together for a full 10.
4. 1 + 6 = 7
1 + 6 = 7. Adding one is just moving to the next counting number after 6, which is 7.
Part C: True or False?
Read each statement. Circle True or False.
1. 3 + 6 equals 9.
True False
True — 3 and 6 are partners that make 9, like 3 pennies plus 6 more makes 9 pennies.
2. 5 + 4 equals 10.
True False
False — 5 + 4 is really 9. You'd need 5 + 5 to reach 10, so the sentence is one short.
3. 1 + 0 equals 1.
True False
True — adding zero doesn't change anything, so 1 with nothing extra is still 1.
