Here are four great maths worksheets for those children who are confident with counting in ones and are ready to move on to counting up in tens from a teen number and then any 2-digit number.
Whilst the four pages concentrate on the same skill, they are all very different.
Don't be surprised if your child uses fingers to help them with this. For example, counting on 3 tens from 21, many children will start at 21, hold one finger up for 31, 2 for 41 etc.
