LET’S BREAK IT DOWN!
Add 3 numbers together.
To add 5 + 4 + 8, first add the first two numbers together. 5 + 4 = 9. Then add in the third number, 8. 9 + 8 = 17.
Add 3 numbers together. To add 5 + 4 + 8, first add the first two numbers together. 5 + 4 = 9. Then add in the third number, 8. 9 + 8 = 17.
Add in a different order.
You can add those same numbers in a different order. 4 + 8 = 12. Then add the 5. 5 + 12 = 17. The answer is the same.
Add in a different order. You can add those same numbers in a different order. 4 + 8 = 12. Then add the 5. 5 + 12 = 17. The answer is the same.
You can break apart numbers to add.
To add 11 + 18 + 50, break the numbers into tens and ones. 11 = 10 + 1 and 18 = 10 + 8.
Add the tens, then add the ones. 10 + 10 = 20. 1 + 8 = 9. The sum of the first two numbers is 20 + 9 = 29. Then add the 50. 29 + 50 = 79.

To add 3-digit numbers, you can break numbers apart into hundreds, tens, and ones.
To add 3-digit numbers, you can break numbers apart into hundreds, tens, and ones.
Add 532 + 120 + 127. 532 = 500 + 30 + 2. 120 = 100 + 20. 127 = 100 + 20 + 7. Add the hundreds, tens, and ones separately, and then combine the place values. The sum is 700 + 70 + 9 = 779.

ADD MORE THAN 2 NUMBERS DISCUSSION QUESTIONS
Add 6 + 5 + 7. What numbers did you add first?
Add 6 + 5 = 11. Then, add the third number. 11 + 7 = 18. The sum is 18.
Add 15 + 47 + 5. What two numbers could you add first to make the problem easier to solve?
Add 15 + 5 first. 15 + 5 = 20. Then, add the other number. 20 + 47 = 67. The sum is 67.
Add 13 + 19 + 7 + 21. What two pairs of numbers could you add first to make the problem easier to solve?
First, add 13 + 7 and 19 + 21. I know that 13 + 7 = 20. Add 19 + 21 = 19 + 1 + 20 = 20 + 20 = 40. Then, add 20 + 40 = 60. The sum is 60.
Add 14 + 13 + 21 + 10.
I can start with any two numbers. I start with 14 + 13 = 27. Then, add in the next number. 27 + 21 = 48. Then, add the last number. 48 + 10 = 58.
Add 212 + 214 + 330.
I can start with any two numbers. I start with 212 + 214 = 426. Then, add in the third number. 426 + 330 = 756.
