Here are some of the games that we have been using in the classroom to practise number facts. The children can also play these at home to reinforce and practise Mental Maths.
Addition and Subtraction Game; adding or taking numbers to reach a target. Some children may find a numberline useful for this game. http://www.eduplace.com/kids/mw/swfs/rockhopper_grade2.html
Doubles; Number Range – doubles to 10, doubles from 5 to 15, doubles from 10 to 20. https://www.topmarks.co.uk/maths-games/hit-the-button
Number Bonds; start off with any of the up to 10 games. Some children may then progress to games up to 20
