Year 4 maths worksheet: Multiply multiples of 10

This page is an excellent illustration of how knowing ‘tables’ and understanding place value can make other maths much simpler. These questions are all multiplying multiples of ten by a single digit.

If you know that 7 x 8 = 56 then 70 x 8 can be done ‘in your head’ very quickly.

probably the hardest questions on this sheet are those set out like this:

490 x 7 = ??

The best way to approach this is to ask what times 7 makes 49? and work from there.
