Using Simple Formulae
Use simple formulae expressed in words or symbols to calculate values (e.g. perimeter = 2 × (length + width))
Suggested ages 10–11
Learning journey
Your child is beginning to work with algebra — using letters to represent unknown numbers, creating and following rules for number patterns, and translating word problems into mathematical equations.
Evidence of understanding
- Substitute values into P = 2(l + w) to find the perimeter of a rectangle
- Use the formula for area of a triangle (A = 1/2 × b × h) given base and height values
- Interpret a formula expressed in words and use it to compute an output
Assessment prompt
If Using Simple Formulae is told that the perimeter of a rectangle uses the formula perimeter = 2 × (length + width), can they plug in the measurements and work out the answer?
