Learners complete the 'challenge' by completing activities on 3 out of 5 topics: Estimation, Puzzles/Games, Value for money, Maths facts and Practical numbers (maths used in everyday life. In addition to this set of Challenge Cards there are four more sets, 3 out of 5 maths scheme Guidance Notes and a marketing flyer.
