Here we have a tricky set of maths worksheets on counting back in tens, starting from any 2-digit number. An important thing to point out to children is that the ones/units will remain the same as the number gets ten less. This is good practice at understanding place value, so important later on.

Counting back is the preliminary stage before subtracting 'in your head'. These worksheets ask your child to count back from numbers up to 20. At first they will probably use fingers or other maths material to count back, but as they gain confidence they will begin to use other mental methods and begin to know the answers ' off by heart'.
