Numberblocks is a great programme to embed maths skills. You can watch it on BBC iplayer https://www.bbc.co.uk/iplayer/episodes/b08bzfnh/numberblocks
Practise counting to 100. Make sure you know what comes after 29, 39, 49 etc. That's the tricky bit. Once you've mastered it, try counting backwards across these boundaries. For example, can you count backwards from 63 to 53?
Ask a grown up for some coins. Can you recognise them all? Set up a shop and practise buying items with the correct coin. Find lots of different ways of making the same amount of money. For example, how many ways can you make 10p. Remember there is no 3p or 6p coin!
Tell the time to the hour and half past.
