Introduce how a fact you already know can help you multiply by a multiple of 10, for example using 3 x 4 to solve 3 x 40, since 40 is ten times as much as 4. Students then practise using known facts to solve multiplication problems involving multiples of 10.
What's included:
Teaching slides introducing how a known fact relates to multiplying by a multiple of 10
8 practice slides using a known fact to solve a related multiplication by a multiple of 10
