What is an example of an array in math?
One such relationship, the inverse relationship between division and multiplication, can be effectively illustrated using arrays. For example; 3×5=15 or 3 rows of 5 make 15, can be represented by the following array. 15÷3=5 or 15 put into 3 rows makes 5 columns – or 5 in each row.

- Example. a) 7 468 -1 235.
- Subtract the Thousands. 6 468 – 200= 6 268.
- Subtract the Hundreds. 6 268 – 30= 6 238.
- Subtract the Tens. 6 238 – 5 = 6 233.

How do you teach an array in math?
Graphing an Array: Give students graph paper and cards with multiplication problems for 2’s and 3’s times tables.
