A clear way to visualise doubling 2 digit numbers to help children calculate doubles mentally. Children are asked to double the tens number, double the units then add the results together.
This pack provides 6 worksheets with 3 levels of differention (2 worksheets for each level).
a) Doubling numbers where the tens and units numbers do not exceed 4
b) Doubling numbers where the tens number does not exceed 4
c) Doubling random 2-digit numbers
The last double on each sheet gives a 'taste' of the next level to judge easily whether the child is ready to proceed.
