Arrays

Did you know that arrays are wonderful ways for our grade ones to begin to develop an understanding of multiplication (groups of) and division (shared between or how many)? Well, they are! 

For example, the first slide of cute kittens shows 3 groups of 4 make 12, and 4 groups of 3 make 12. It also shows that 12 how many 3s are 4, and 12 how many 4s are 3. 

There are 36 slides in all - can you tell 'groups of' and 'how many' stories from the pictures?
