A progression of mental maths strategies for addition and subtraction from a basic level to GCSE level. The strategies are grouped as ‘Change’, ‘Split’ or ‘Jump’. It invites students to change a problem, to an easier form, before splitting numbers or/and jumping along the virtual number line that exists in their heads. This is a useful resource for Maths teachers of all age groups to see what are the next steps for their students and also to see the range of different possible strategies available.

A 25 slide PowerPoint showing an incredible amount of things you can do with a 7 piece tangram. It covers 2D shapes, angles, area, proportion, percentages, fractions, square-roots, symmetry, compass directions, algebra, bearings and vectors. There is at least a weeks material for a KS3 or KS4 class and also could be used as revision. Please review it if you download it and put it to good use. The ideas used are adaptable and could be used for other square based patterns. It has interesting animations and some of the ideas are easier to access through animation.
