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 with 3 and count up 4 more: 4, 5, 6, 7. So 3 + 4 = 7.
2. 1 + 6 = 7
Begin at 1 and count on 6 more to land on 7. So 1 + 6 = 7.
3. 5 + 2 = 7
Putting 5 things and 2 things together makes a group of 7, so 5 + 2 = 7.
4. 4 + 4 = 8
Two equal groups of 4 make a doubles fact: 4 + 4 = 8.
Part C: True or False?
Read each statement. Circle True or False.
1. 2 + 5 = 7
True False
True. 2 + 5 = 7, so the number sentence is correct.
2. 4 + 3 = 6
True False
False. 4 + 3 actually makes 7, not 6. You can check by counting 4 fingers and then 3 more.
3. 1 + 8 = 9
True False
True. 1 + 8 = 9 because adding 8 onto 1 gives a total of 9.
