Read each question carefully and use the addition strategy specified to solve it. Show your work where applicable.
1. Use mental math to find the sum of 145 + 320.
2. What is 287 + 513 using a mental math strategy?
Use the number line strategy to complete the following:
3. To add 35 + 18, you can start at 35 and jump forward 10 to reach , then jump forward another 8 to reach .
4. Show how to add 72 + 25 on a number line. The sum is .
5. Which of the following shows the correct way to break apart 56 + 37 to add?
(50 + 6) + (30 + 7) = 80 + 13 = 93
(5 + 6) + (3 + 7) = 11 + 10 = 21
(56 + 30) + 7 = 86 + 7 = 93
Both a and c
6. Explain how you would use the compensation strategy to add 199 + 45. Then find the sum.
7. Apply the compensation strategy to solve 348 + 202.
8. The Commutative Property of Addition states that changing the order of addends changes the sum.
True
False
Match each addition strategy with its example.
9. Breaking Apart
a. 50 + 30 + 7 + 2
10. Compensation
b. 99 + 1 = 100, then 100 + 45 = 145
11. Number Line
c. Start at 25, jump 10, jump 5
