GST Maths Unit - Year 5

Give Year 5 students a clear, practical pathway through Australian Goods and Services Tax (GST). This complete digital maths unit combines explicit teaching with worked examples, collaborative activities, money and decimal practice, budgeting, error analysis and assessment.

Students learn to distinguish pre-GST price, GST amount and GST-inclusive price; calculate 10% GST; calculate an inclusive price by multiplying by 1.1; recover a pre-GST price by dividing by 1.1; find the GST component of an inclusive amount by dividing by 11; choose an appropriate operation; and check that an answer is reasonable.
