Explain how understanding place value (tens and ones) can help you add the numbers 42 and 35.

Understanding place value allows you to add the tens (40 + 30) and the ones (2 + 5) separately, then combine the results.

I can represent two-digit numbers using tens and ones.

1
In the number 37, the 3 represents 3 tens, which has a value of 30, and the 7 represents 7 ones.
2
In the number 82, the digit 8 is in the tens place, representing 8 tens, or 80.
3
When adding 23 + 14, you can add the tens (20 + 10 = 30) and the ones (3 + 4 = 7) to get 37.
