Students work with a scaled floorplan of four rooms, adjust the drawing scale to calculate real floor area, then set a ceiling height and extend the same plan into a 3D model to calculate room volume. The full interactive is available to licensed Education Universe users.
Ask students what changes, and what stays the same, when the drawing scale changes.

A guided Year 8 investigation showing how the area formulas for parallelograms, trapeziums, rhombuses, kites and composite shapes are derived by rearranging, duplicating…
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.
Students investigate where the formula A = πr² comes from by progressively slicing a circle into sectors and rearranging them into a rectangle-like shape. They work…
A guided investigation in which students connect radius, diameter and circumference, measure how many diameters fit around a circle, discover π as the…
Students rotate 3D composite objects, separate them into their component solids, and add the individual volumes to find the total. The full interactive is available to…
Area & Volume is one of the licensed interactives in The Education Universe. This page describes it; teachers use it in lessons and classes with a licence or the free trial.
