Which pair of numbers adds to 9?

4 + 5 — 4 + 5 = 9, while 3 + 5, 2 + 6, and 1 + 7 each equal 8.

Which pair of numbers makes 10?

7 + 3 — 7 + 3 = 10, while 3 + 6, 5 + 4, and 2 + 7 each equal 9.

6 + 2 — 6 + 2 = 8, while 2 + 5, 3 + 4, and 4 + 3 each equal 7.

6 + 2 — 6 + 2 = 8, not 7, while 3 + 4, 5 + 2, and 1 + 6 all equal 7.

6 + 4 — 6 + 4 = 10, while 4 + 5, 3 + 6, and 5 + 4 each equal 9.

Part A: Trace the Words

Trace each word carefully by following the dotted lines.

1. total

2. plus

3. add

4. sum

5. equal

6. more

Part B: Fill in the Blank

Write the missing word or number on each line.

1. 3 + 4 = 7

3 + 4 = 7. Start at 3 and count up four: 4, 5, 6, 7.

2. 5 + 2 = 7

5 + 2 = 7. Keep 5 in your head and take two jumps forward: 6, 7.

3. 1 + 8 = 9

1 + 8 = 9. It is easier to flip it to 8 + 1 — the number right after 8 is 9.

4. 6 + 4 = 10

6 + 4 = 10. Six and four are number-bond partners that make a full ten.

Part C: True or False?

Read each statement. Circle True or False.

1. 2 + 3 is the same as 5.

True False

True — 2 fingers on one hand and 3 on the other make exactly 5 fingers in all.

2. 4 + 4 equals 9.

True False

False — 4 and 4 are a double that makes 8, not 9. The sentence is off by one.

3. 0 + 7 equals 7.

True False

True — adding zero means nothing is added, so 7 stays as 7.
