Education Technology
Students solve problems involving the associative, commutative and distributive laws, investigate index notation and represent whole numbers as products of powers of prime numbers. They work with fractions including addition, subtraction, multiplication and division including those with unrelated denominators. Students are introduced to the concept of a variable. They create algebraic expressions and evaluate them by substitution, extend the laws of arithmetic to algebraic expressions and solve simple linear equations.

Year 7: Factors that Count image

Standard ACMNA149

Investigate index notation and represent whole numbers as products of powers of prime numbers

Activity: Factors that Count

Students use factor trees to determine the prime factorisation of a number and write the result as a product of its prime factors. Students then manipulate the prime factors to produce all the factors.  Using an inquiry based approach, students explore the relationship between the prime factorisation and the quantity of factors.
