Turn a 3D model into a maths investigation

Ask learners to predict, build, compare and explain. A useful project makes the mathematical reasoning visible alongside the final artwork.

Choose one question

Keep the first activity small enough that students can inspect individual objects and repeat a calculation by hand. These prompts connect a visual change to a specific mathematical idea:

Symmetry: how does changing the number of repeated sectors change the angle between them?
Volume: why does doubling every dimension multiply a solid’s volume by eight?
Waves: what changes when amplitude changes but spacing stays fixed?
Spirals: how many steps complete a turn, and how does the radius grow?

A 40-minute lesson sequence

5 minutes — predict. Show a small model and ask students to sketch what one changed setting will do.
10 minutes — build. Reproduce the model, record its settings and inspect one object’s formula.
10 minutes — compare. Make two versions that differ in only one setting. Explain which measurements should stay the same.
10 minutes — explain. Connect a screenshot or diagram to a worked calculation.
5 minutes — reflect. Compare the prediction with the result and name one assumption or limitation.

Adjust timing for age, prior knowledge, device performance and accessibility needs. Pair work can help: one learner changes the model while another records settings and checks the prediction, then they swap roles.

Project: rotational symmetry

Start with one recognisable shape and repeat it around a centre. Six equally spaced copies have a turn of 360° ÷ 6 = 60°. Compare five, six and eight copies while keeping radius and shape size fixed.

Ask students to identify the centre, explain the rotation that maps one copy onto the next, and distinguish rotating a copy from moving its centre. A pattern can have rotational symmetry even if the individual source shape does not.

What students should submit

A question and prediction.
The original and changed settings, including units.
A screenshot, exported project sheet or other permitted evidence.
One calculation tied to a particular object or measurement.
An explanation of the result, including a limitation or further question.

Mark the reasoning as well as the picture. A reproducible project with a clear explanation is stronger evidence than an elaborate model with no record of how it was built.

Using Campus assignments

With an active Campus licence, a teacher can create an assignment, set a deadline and late-submission rule, and publish it to the class. Students submit a saved project snapshot. The teacher can grade it and return feedback. A resubmission replaces the submitted version and clears the previous grade so the new work can be assessed.

Check the class licence, available seats, sign-in and export allowances before the lesson. Use the Campus enquiry form for a school pilot, or contact info@almajeedgroup.in.

Prepare a fallback

Browser-saved work and cloud-saved work are different. Ask learners to save a local project copy when appropriate, and confirm that online saves show as complete before changing devices. If the geometry server is unavailable, a lesson about pattern coordinates can still use the browser’s model and formula views.
