Array Cards

Array Cards

This set of sixteen cards allows children to both visualise and count arrays of dots. An array helps with the commutative property of multiplication and with the development of effective mental strategies.

Arrays are also a powerful aid to understanding factors and multiples. For example, a four by three array for 12 can be fitted twice into a four by six array for 24.

Array Cards Without Numbers

These cards feature the same set of sixteen cards with rectangular arrays of coloured dots as those shown on the left. The only difference is that they have no numbers or calculations. They can be found by clicking here.
