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.

To determine whether each of the given quantities is greater than, less than, or equal to 1,000, you need to compare them to the value of 1,000.

Let's go through each quantity one by one:

1. 10 rows of 10 squares: Since each row has 10 squares, the total number of squares would be 10 × 10 = 100. Since 100 is less than 1,000, we can say that it is less than 1,000.

2. 10 rows of 10 hundreds: In each row, there are 10 hundreds, so the total would be 10 × 10 = 100. Now, we have 100 hundreds. Since each hundred is equal to 1,000, the total value would be 100 × 1,000 = 100,000. As 100,000 is greater than 1,000, we can say that it is greater than 1,000.

3. 100 rows of 10 hundreds: In each row, there are 10 hundreds, so the total would be 10 × 100 = 1,000. Now, we have 100 rows, which means we have 100 × 1,000 = 100,000. As 100,000 is greater than 1,000, we can say that it is greater than 1,000.

4. 1 row of 10 hundreds: In this case, we have only one row with 10 hundreds, so the total would be 10 × 1,000 = 10,000. As 10,000 is greater than 1,000, we can say that it is greater than 1,000.

So, to summarize:

- 10 rows of 10 squares: Less than 1,000
- 10 rows of 10 hundreds: Greater than 1,000
- 100 rows of 10 hundreds: Greater than 1,000
- 1 row of 10 hundreds: Greater than 1,000
