We are working on multiplication in class!

An array is a rectangular pattern of items arranged in columns and rows.

When we describe arrays, we write the number of columns first.

Therefore, this array would read 6 x 3!

Try the array activities posted here for additional practice.

A Game to Print and Try at Home: Racing Rectangles….click link below to print out the grid for playing.

Racing Rectangles is a game that can help reinforce arrays and multiplication. Students, working in pairs, take turns rolling two dice. Each student must choose a different colored marker or crayon to use. The student outlines and fills in a rectangle that matches what they rolled.

For example, if the student rolled a 4 and 3, that student would fill in a 4×3 rectangle on the grid. The player then writes the total number of squares inside the rectangle.

A player loses a turn when his or her rectangle cannot fit on the game board. Play continues back and forth until neither player can’t draw a rectangle.

Students count up their total of squares they colored.

The winner is the one with the highest number of squares filled in.

Here is an example of what a game board might look like…
