Fractions – a visual introduction

MathematicsNumbers & ArithmeticAges 11–12

Build a fraction with circles, bars, cups of water, cakes or a number line: drag pieces from the bucket into a shape or tap to shade and unshade, change the numerator and denominator with counters, and see the matching mixed number and decimal straight away. There is a Game screen with 4 levels (read the picture, build the picture, equivalent fractions, mixed numbers) and a free Lab screen with a wider range of denominators. Based on the "Fractions: Intro" simulation by PhET Interactive Simulations, University of Colorado Boulder (CC BY 4.0); rewritten.
