Free Year 4 maths practice — classify triangles and quadrilaterals, identify angles and reason with line symmetry. No account needed.
Classify supplied triangles and quadrilaterals, identify acute, right and obtuse angles, count symmetry lines and complete a reflected triangle. 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.
Learning objective: Use visible geometric properties to classify shapes and angles and reason about line symmetry.
Curriculum anchor: England Year 4 mathematics: classify triangles and quadrilaterals, identify acute and obtuse angles, identify line symmetry and complete a symmetric figure.
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.
Ask the learner to justify each choice using a visible property, then verify reflections by checking equal perpendicular distances from the mirror line. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.
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.
