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 units will remain the same as the number gets ten less. This is good practice at understanding place value, so important later on.

How many tens did you count?

An abacus is an excellent resource for helping your child understand 2-digit numbers up to 99. It shows clearly the two columns, the units and the tens. In other words the 2 yellow balls in the tens column have a value of 20 whilst the two balls in the units column have a value of 2. This will also help later when multiplying by 10 as they can see each digit moving one place to the left.
