Arrays in Math - Are You Teaching It Correctly?


This array represents 7 x 6 = 42
It's SEVEN rows of SIX columns.

I checked with a Math Facilitator at D.E.S.E. over Christmas Break, and she said to teach it this way too.

5 x 4 = 20 would be FIVE rows of FOUR columns.
4 x 5 = 20 would be FOUR rows of FIVE columns.

Consider asking your students to form arrays when seated on the carpet. You could ask for six rows of four columns (if you have 24 students) which would represent 6 x 4 = 24.

If your numbers won't divide evenly ... consider teaching remainders.
