Interactive Integers from TicTacTech

Interactive Integers – Addition and Subtraction

 Perfect for learning how to add and subtract positive and negative numbers!

This app provides two fun interactive methods for learning and understanding addition and subtraction of positive and negative numbers. The color tile model and number line model are two of the most common classroom methods for teaching integers. These methods help students visually understand integer concepts instead of relying only on memorization of rules.

★ Color Tiles:

  • Allows students to drag yellow positive tiles and red negative tiles around the screen to solve addition problems.
  • Problems are guided with step-by-step directions
  • Information screen provides detailed explanations and examples

When a positive and a negative tile are dragged on top of each other they will disappear because one negative and one positive makes zero!

 ★ Number Line:

  • The touch functionality of the device allows students to bring the number line model to life.
  • Problems are guided with step-by-step directions
  • Information screen provides detailed explanations and examples

★ Practice:

  • Allows students to practice adding and subtracting integers. Problems are guided with step-by-step directions
  • Flexible options – choose number of problems, problem difficulty and choose add/subtract/both
