Year 6 Maths Starters/plenaries

These are aimed at Year 6 in term 1 and perhaps to a top set Year 5 maths class (as I intend to use them). I have pinched the questions off a recent resource (cannot remember from where) but I have added them all onto separate PowerPoint slides followed by my own answers and explanations. All are relevant to the current curriculum. The answers are all revealed slowly to allow time for discussions. I will be using these for lesson starters or plenaries and they are aimed at all levels within the classroom. Would love to hear what you think and how the children got on.
