Number & Algebra

Chapter 7 | Expressions, formulae and equations

These are problem solving open-ended questions that require students use formulae. The tasks can be given at the start of a topic and done as the students gain enough knowledge to complete them, inserted into a topic at an appropriate place or given as homework or extension.

Explores how formulae can be written from rules written in words and how they are used to model situations.
Gives practice at using formulae to solve problems.

Explores writing equations for Cuisenaire rods and how these equations can be written in different ways.
Introduces solving equations using inverse operations using “I think of a number” problems.
