X 4


We have been looking at using our doubles and halves knowledge to multiplying and divide numbers. Did you know that four is the same as 2x2? Well if you double a number (x2) then double again you get the same answer as times 4. If you half a number and half again it is the same as dividing by 4.

Check out our show me to see what we mean.
