Algebraic Techniques 1
Outcomes

Introduce the concept of variables as a way of representing numbers using letters (ACMNA175)

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
Examples

 Extend and apply the laws and properties of arithmetic to algebraic terms and expressions (ACMNA177)
 Simplify algebraic expressions involving the four operations (ACMNA192)
