Students learn about simplifying expressions by collecting like terms. As learning progresses they consider a mixture of unkowns and numbers. More able students also work with unknowns to a different power.
At the start of the lesson they recap forming expressions using shapes. In the main they learn how to simplify expressions by identifying like terms. At the end they are challenged to complete a magic square using algebraic terms.
Differentiated Learning Objectives
- All students should be able to simplify algebraic expressions involving a single unknown.
- Most students should be able to identify and collect like terms to simplify algebraic expressions.
- Some students should be able to simplify algebraic expressions with different powers.
