An array is a rectangular arrangement of items into rows (each with an equal number of items) and columns (each with an equal number of columns)This is a great video that you can show your students or use as a teaching resource.
Here's a helpful worksheet
This is a fun game that I might use to teach students about using an array to solve multiplication equations.
Array Arrangement: Multiplication
Using a pair of dice, the students are to draw the product on graph paper as a rectangular array.
For example, if a 4 and a 3 are rolled, that means 4 x 3 = 12. The array is drawn as 4 rows and 3 columns, to make a rectangle. Each time a square number is drawn, let the students color it in red. Label each array with the number sentence it goes with.
