Maths Quiz - Year 1 Numbers - Order of Numbers (Answers)
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 recognising one more or one less than a given number.
Finding one more or one less than is all about understanding the order of numbers and knowing where they are in relation to each other. It's about being able to confidently count forwards or backwards and being able to add or subtract one from a number by counting up or down and knowing what is one more or one less than a given number.
