Mixed numbers – pictures, number line and practice game

MathematicsNumbers & ArithmeticAges 11–12

The Intro screen uses two spinners to set the numerator and denominator and shows the improper fraction or the matching mixed number on circles or rectangles split into equal parts and on a number line. The Game screen has 3 levels × 6 questions mixing three types: read a mixed number from a picture, convert an improper fraction to a mixed number and convert a mixed number to an improper fraction, with up to 2 attempts per question and scoring. On the Lab screen, tap to shade parts across several shapes, then work out the total as a fraction and as a mixed number. Based on the "Fractions: Mixed Numbers" simulation by PhET Interactive Simulations, University of Colorado Boulder (CC BY 4.0); rewritten.
