Arrays

​We use arrays to show equal groups.

​

​We can multiply ROWS x COLUMNS

​

​OR

​

​ROWS x SIZE OF EACH ROW

​

​to find the total.

Multiple Choice

What multiplication expression does this array show?

• 5 + 3

• 3 x 5

• 3 + 5 

• 15 ÷ 3

​Multiply with CUBES

​When we multiply, we know the...

​NUMBER OF GROUPS (G)

​and

​SIZE OF GROUPS (S)

​

​We need to find the total!

​

​Remember...to multiply (x) we always have equal groups!

Multiple Choice

Look at the array! What number goes into the blank to make the number sentence true?

8 x 3 = ( ____ x 3) + (3 x 3 )

• 5

​Division

​When we divide, we know the TOTAL (or big boss number) and we are splitting it up into smaller parts.

​

​To divide, we can FAIR SHARE (if we know the number of groups) OR we can use the "GROUPS OF" strategy!
