The final week of Unit 2: algebraic fractions with multiplication and division, then two days pulling everything together — mixed problem solving and forming equations from real-life situations, before a self-directed review and the Unit 2 assessment.

Week 6 takes last week's multiplying skills and applies them to brackets — expanding by multiplying everything inside a bracket, then the reverse process, factorising. We finish by forming algebraic expressions from written descriptions, putting the whole week's skills to use.

Unit 2 begins: Algebra. This week covers the notation itself, simplifying expressions by collecting like terms, substitution, and multiplying/dividing terms — the same rules of arithmetic you already know, just written in a more general way. Same tiered format, warm-ups that build on what you already know.
