Make arrays to model multiplication
key notes :
Arrays are made up of rows. All the rows have the same length.
This array of squares has 3 rows with 4 squares in each row.
Learn with an example
Make a rectangular array of squares to model 2 × 3 = 6.
An array that models 2 × 3 = 6 has 2 rows with 3 squares in each row.
There are 6 squares in the array.
Make a rectangular array of squares to model 4 × 3 = 12.
An array that models 4 × 3 = 12 has 4 rows with 3 squares in each row.
There are 12 squares in the array.
Make a rectangular array of squares to model 3 × 3 = 9.
An array that models 3 × 3 = 9 has 3 rows with 3 squares in each row.
There are 9 squares in the array.
