Number Compare



This manipulative provides opportunities to:

  • Compare two quantities using groups of objects

  • Select from different objects or use number cards, which can be combined

  • See an equation or inequality along with a verbal description

  • Observe changes and compare the two quantites using a bar graph or number line

  • Remove supports in the "lab" version where work is in a more free-form setting with the option to use ten-frames or create equations/inequalities with number tiles

PhET also provides translated versions of the simulation in multiple languages, teacher created activities, and with a free account you can access their teaching resources.
