Multiplication Magic

We have been learning to use skip counting to help us to multiply. We have learnt to skip count in twos and tens. We have also learnt that we need to make 'groups of' when we work out a multiplication problem.
The videos below show that we have learnt to make 'groups of' and use skip counting to work out the correct answer.
We are also learning to divide. This is a bit more difficult to understand.
