Maths KS3: Mental add and subtraction game Got it!

From the set of 15 problems, originally created by NRICH, which link to a strand of mathematical processes and applications and to the sub-strands of content. This is a motivating context in which learners can use their mental addition and subtraction skills. However, the real challenge is not the More…calculation but the search for a winning strategy that will always work. This involves conjecturing, refining ideas, generalising and using knowledge of factors and multiples to aid efficiency.
