Time to recap multiplication arrays. You may have forgotten what an array is - make sure you watch this clip:
We're going to use them to figure out multiplication and division facts. For example, if I had this array:
It's 3 across and 5 down, so it shows 3 x 5. How many dots are there? 1, 2, 3...15.
So this shows us 3 x 5 = 15, and 5 x 3 = 15.
How does it show us division? Well, if I were to take 15 and shared it into 3 equal groups (aka division by 3!) how many dots would be in each group?
3 boxes with the same amount - 5 in each box. So the division sum we get is -
15 ÷ 3 = 5.
But wait, there's more! If I shared it into 5 equal groups (divide by 5), how many do you think each group would have?
If you said 3, congrats!
So the other division sum this array shows is
15 ÷ 5 = 3.
See if you can have a go at working out what multiplication and division sums you can get from the arrays on the sheet below.
