Build arrays
Concept:
Description:
Number Range:
Materials Needed:
Players:
Players use counters to build arrays when they roll a dice.
Purpose
Practice multiplication by building arrays
Materials
- 1 Dice per pair
- Counters (bottle tops)
- Scrap paper
- Pencils
How to play:
- One player rolls the dice twice
- The first number rolled tells how many rows to make in an array.
The second number rolled tells how many counters to put in each row of your array (to make up the columns) FOR EXAMPLE: If a learner rolls a 2 and then a 5, they might make an array like the example in the photo- Players must first make the array with their counters and then draw each array made, recording how many rows, how many columns, and how many counters altogether. Encourage them to write either a repeated addition sum or a multiplication sum for each array FOR EXAMPLE 2 x 5 = 10; 5 x 2 = 10; 2 + 2 + 2 + 2 + 2 + 2 = 10; 5 + 5 = 10
