Maths Without Limits
Opening Young Minds to Endless Possibilities

This unit explores the idea that carrying out certain calculations mentally (eg doubling, halving, multiplying and dividing by ten) is relatively easy and that these operations can then be combined to perform other calculations such as multiplying and dividing by 4, 8, 5, 20 etc.
We begin with three different visualisations (double number bond diagram, place value chart and function machines).
We then explore the effect of combining operations.
Once the concept is understood, we consolidate with a talking game and pair challenge game.
