I've uploaded a sheet of matchstick problems to do as a bit of a starter (the children in school have really enjoyed doing them). There's one easy, one medium and one hard. Just see what you can do in about 15-20 minutes.
The other sheets are independent tasks based on the learning from the guided sheets. They get progressively more challenging as you work through both pages just so you are aware.
For those of you that are confident with this maths, there are some challenge questions for you to do as well. There is a video walkthrough of the worksheets, but the challenge stuff (if you've managed to get that far) I would like you to attempt without my help for now.
