We've seen how multiplying by 2 helps us 4, and then by 8. Let's try this problem to help us remember.
Find 6 \times 8.
What if we could use things we already know to solve multiplication or division? We can. Let's see how.
If 2 \times 8 =16, what is 20 \times 8?
uses mental and informal written strategies for multiplication and division
generalises properties of odd and even numbers, generates number patterns, and completes simple number sentences by calculating missing values
