Happy Home Education

Week 2 builds straight on last week's arithmetic: factors, multiples, primes, and the two ideas that trip most people up first time round, HCF and LCM. Same tiered format as Week 1, warm-ups that recall what you already know, and a Friday consolidation before we move on to powers and roots.

This week, we’ll explore how factors and multiples lead to more powerful number tools: Lowest Common Multiple (LCM) and Highest Common Factor (HCF). We’ll also look at index notation for repeated multiplication and standard form, which helps us write very large and very small numbers simply.
