Why not pick one episode a day and try the following:
- Can you form that number neatly?
- Can you make that number in lots of ways e.g. 3 bananas, 3 socks, 3 stickers.
- Can you make that number in different ways? e.g. 2 red stickers and 1 blue sticker makes 3 altogether.
In addition to this, lots and lots of practical opportunities to count and compare amounts are always very very helpful.
