Instructions

Play through this interactive game to learn about Describe Why Opposites Sum Is 0. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

A fundamental fact about addition of rational numbers is that p + (-p) = 0 for any rational number p.

A number and its opposite are referred to as additive inverses and always are = 0 when added together.

Use situations to describe why this is true (An elevator goes up three floors then down three floors etc)
