What students learn in AC9M10A01
This unit helps students build a clear, usable understanding of Expand, factorise and simplify expressions and solve equations algebraically, applying.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: expand, factorise and simplify expressions and solve equations algebraically, applying exponent laws involving products, quotients and powers of variables, and the distributive property.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- explaining the relationship between factorisation and expansion, including the completed square form for quadratic expressions applying knowledge of exponent laws to algebraic terms and using both positive and negative integral exponents to simplifying algebraic expressions and solve equations algebraically
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
