Teaching guide

What students learn

Experiment with functions and relations using digital tools, making and testing conjectures and generalising the patterns.

How to teach it

Build algebra from arithmetic: use a variable to stand for an unknown, write the situation as an expression or equation, then keep both sides balanced when solving and check by substituting the answer back in.

Worked example

3x = 21

Answer: x = 7

Why: Divide both sides by 3: x = 21 ÷ 3 = 7

Generated and checked in code, so it is correct.

Watch out for

Treating the equals sign as 'work it out' rather than 'both sides are equal', dropping negative signs, and not applying an operation to every term.
