Maths Challenge Mastery Cards. (set 2)

This is another set of Math Mastery Challenge Cards. I have used these successfully with Year 5 and Year 6 children. They are useful for SATs revision, particularly in developing children's reasoning.
There are 8 challenge cards in this set. Each card gives children a problem to solve and asks them to explain or justify their answer.
These could be used as an additional challenge or as a whole lesson. I have given children the whole set and asked them to select one card. They then stick the card in their maths book and then write their solution next to it, explaining their reasoning. The children loved the activity!
