*This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 5 and 6 in year 1. Specifically this quiz is aimed at the section dealing with counting in tens. *

Counting forward and back in tens is a really useful skill. It is one of the first kinds of number patterns children encounter and a good understanding will help with lots of other areas of development, including recognising sequences, counting forward and back quickly, and ten times table recall.
