Introduce the concept of variables as a way of representing numbers using letters (ACMNA175)
Outcomes
-
Develop the concept that pronumerals (letters) can be used to represent numerical values
Examples
-
Recognise and use equivalent algebraic expressions, eg y + y + y + y = 4y
Examples
-
Use algebraic symbols to represent mathematical operations written in words and vice versa, eg the product of x and y is xy, x + y is the sum of x and y
