Area of Quadrilaterals Guided
A guided Year 8 investigation where students derive area formulas by rearranging parallelograms, duplicating trapeziums, using diagonals for rhombuses and kites, and…
Area Units Visualiser
Predict how many small squares fit in a larger one and fill it row by row, practise conversions on a km² → mm² ladder, and compare real objects with 1 m², 1 ha and 1 km².
Circle Area Investigation
Investigate where the formula A = πr² comes from by progressively slicing a circle into sectors and rearranging them into a rectangle-like shape. Students work through a…
Circle Circumference & Pi Guided
A guided investigation where students connect radius, diameter and circumference, measure how many diameters fit around a circle, discover π as the…
Design the Festival Site
A story-driven capstone challenge where students design a festival site by solving connected problems involving percentages, linear equations, circumference, circle…
Inverse Trigonometry Active Lab
An active lab using geological drillhole data to reconstruct underground drilling angles with inverse trigonometry, then inspect the selected drillhole within its local…
Mission: Mars Base
A story-driven capstone challenge where students stabilise a Mars research base by solving connected problems involving scientific notation, rates, percentages, linear…
Park Site Designer
Place and resize rectangles and right-angled triangles on a scaled site to meet minimum areas and a fence budget, then calculate and check every area and perimeter.
Perimeter Area Investigation
An investigation where students compare perimeter and area across rectangles, triangles, parallelograms, trapeziums, rhombuses, kites, circles and composite shapes,…
Swimming Pool Volume Investigation
Investigate how to determine the volume of a swimming pool using a rotatable 3D model. Students identify the key measurements required, determine an appropriate method…
The Coastline Paradox — How Long Is Australia's Coastline?
Why do official sources disagree about the length of Australia's coastline? Students walk rulers of different lengths around the real mainland coast, measure maps at…
