Free Year 5 Maths practice — use supplied rectangle properties and aligned lengths to find missing sides. No account needed.
Use invariant rectangle properties and aligned total lengths to find selected missing horizontal sides in split and composite rectilinear shapes. 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: Recognise supplied rectangle properties and calculate selected missing aligned horizontal lengths. Independent drawing, measuring, proof, perimeter and area are not assessed.
Curriculum anchor: England Year 5 mathematics: use the properties of rectangles to deduce related facts and find missing lengths and angles.
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.
Mark equal opposite sides and check which horizontal parts combine to make the full width. 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.
