My third grader brought home this math problem:

Here are five arrays for 36.
1. Lable the dimension for each array.
2. Write a multiplicatiuon sentence for each arrray.

 


Hi,

Here is one array of 36 items.

Its dimensions are 4 and 9, or you might say this is a 4 by 9 array. We always mention the rows first and then the columns. The multiplication sentence is

4 9 = 36
