My son is working with grid paper, the question asks:
tell if each is greater than, less than or equal to 1,000.
10 rows of 10 squares
10 rows of 10 hundreds
100 rows of 10 hundreds
1 row of 10 hundreds

10 rows of 10 hundreds is one thousand.

100 rows of 10 hundreds is 100 x 1000 or one hundred thousand;
1 row of 10 hundreds, 1 x 1000 is a thousand.
