Class 5 maths is the bridge to secondary school. Numbers rise to ten million, the child meets HCF and LCM, learns to add, subtract, multiply and divide unlike fractions and mixed numbers, and then moves to ratio, decimals, percentage, averages and the unitary method. The Course Book handles that load in its familiar Oxford pattern: chapter opener, In Focus questions, Let’s Learn, Activity Time and Practice.
