Frequently asked
What is the fraction playground?
An interactive page where you build fractions by tapping or dragging to colour in pieces of a shape, then add, subtract, multiply or divide them and watch the answer appear.
Is it good for the classroom?
Yes. The shapes are large and high-contrast for projector or whiteboard display, and work by tap or click, so they suit both a child playing and a teacher demonstrating.
Do I need to install anything?
No. It runs in any modern browser on a phone, tablet, laptop or interactive whiteboard, with nothing to install and no sign-up.
Can I switch between bars and pies?
Yes. Use the Shape buttons to swap between fraction bars and pie shapes, whichever helps the concept click.
