https://home.oxfordowl.co.uk/kids-activities/fun-maths-games-and-activities/ Oxford Owl games are for children aged 3-5, 5-7 and 7-9 years old. There are printable worksheets to reinforce the skills practised in the games.
https://www.bbc.co.uk/bitesize/subjects/z826n39 This is more of an interactive learning experience than a set of maths games. Children click on a skill they would like to learn which takes them to a learning page. There they find a video teaching them the skill beneath which are step-by-step written instructions. Each written instruction is accompanied by an interactive activity so children can practise what they have learnt at each stage. If children are having difficulty mastering a particular mathematical concept at school then this is a particularly useful website to explore.
