when subtracting 288 from 506 how would thinking of 500 as 50 tens help you?

Round 288 t0 300 and Round 506 to 500.
BTW, the Subject is not 3rd grade but Math, if you wish a Math teacher to read your post.

506 - 288 = ?
If you have 50 tens, then borrowing one ten for the ones column (to give you 16 - 8) leaves you 49 tens remaining. Then you can subtract 8 from the 9 remaining in the tens column and the 2 from the 4 in the hundreds column.
Does that help you understand?
