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. Take a break when you need one.
