Geometry Lab

Free Year 3 geometry practice — compare angles with a right angle, recognise line types and find perimeter from supplied side lengths. No account needed.

About Geometry Lab

Compare generated angles with a right angle, connect right angles with turns, recognise supplied line descriptions and add supplied side lengths to find perimeter. The default practice mode is untimed, so the learner can think before choosing. Correct answers build a gentle celebration; mistakes receive corrective feedback and return later rather than causing a penalty spiral.

Curriculum purpose

Learning objective: Recognise angles and compare them with a right angle, identify line relationships and find perimeter from supplied side lengths.

Curriculum anchor: England mathematics programme of study: Year 3 geometry and measurement.

This game is designed as short independent practice after an idea has been introduced. It does not replace direct teaching, mathematical or scientific discussion, or an adult checking whether the learner can explain the idea away from the screen.

For parents and carers

Follow the screen practice with drawing, turning and measuring real shapes. The game does not assess physical angle hunts, drawing accuracy or ruler use. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.

Frequently asked questions

Does it need an account? No. The game runs in the browser and asks for no name, email address, school or location.

Is it timed? Practice is untimed. Where a sprint exists it is optional. Times Tables Sprint also includes MTC-style independent practice, not an expected-standard judgement.

Can it be used on a phone? Yes. Buttons support touch and keyboard use; sorting always has a tap alternative to dragging.
