Sign in to playTwo points A and B can be dragged along a number line to read and compare integers. The Situations screen links integers to three familiar contexts: temperature (a thermometer), height above sea level and a bank account balance. The Number line screen offers ranges of ±10, ±30 or ±100 for practising opposites and absolute value on a plain number line. Adapted from the "Number Line: Integers" simulation by PhET Interactive Simulations, University of Colorado Boulder (CC BY 4.0); rewritten.
