Instructions
Play through this interactive game to learn about Arithmetic of Rational Numbers on a Number Line. 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.
Use situations to describe why p + (-p) = 0 for any rational number p is true (ex: An elevator goes up three floors then down three floors).
Interpret negative number addition and subtraction expressions that describe real-world contexts.
Discussion Questions
Before the Game
In a football game, if someone loses yards, how do we represent that with a number? What are rational numbers? How do we add a positive number to a negative number?
After the Game
Why might we use a football field to demonstrate positive and negative numbers? What is the additive inverse and why might we want to use that?
