What children learn in Level 16

A stadium has 124 rows with 38 seats in each. To find every seat, think of equal groups. There are 124 groups of 38.
Estimate first. 100 times 40 is 4,000, so the answer should be somewhere around there.
Now pick your method. With the standard algorithm, the lines are 992 and 3,720, and the total is 4,712.
Check it against the estimate. 4,712 is near 4,000, so it makes sense. Then answer with the words of the story: 4,712 seats.
