Get ready to explore numbers in lots of exciting ways! In these Christmas themed worksheets, children will practise finding 1 more, 1 less, 10 more and 10 less than a given number. They’ll solve true or false challenges, use colouring activities to show their answers, and think carefully about how numbers change. The activities are designed to strengthen place value knowledge, encourage mathematical reasoning, and help identify common misconceptions (such as confusing 1 more with 10 more).
