Description

Play as a human pretending to be in a robot society, where humans are not allowed. Our brave player is fighting for their survival (to pass as a robot) by showing off skills constructing linear relationships from real-life examples!

Vocabulary Words

rate of change

linear function

slope

x-value

y-value

undefined slope

no slope

function

initial amount

graph

y-intercept

constant

linear function

y = mx + b

Instructions

Play through this interactive game to learn about Linear Relationships. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Interpret real world situations as functions (Interpret the situations for starting point, and rate of change) in context.

The starting point for a function is the first value of the input.

The rate of change is the slope of the interpreted function of the graph.

Construct functions to model real world situations.

Determine the y-intercept of a function.

Construct a function to model a linear relationship between two quantities.

The slope of a vertical line is undefined and the slope of a horizontal line is 0. Either of these cases might be considered “no slope.” Thus, the phrase “no slope” should be avoided because it is ambiguous and “non-existent slope” and “slope of 0” should be distinguished from each other.

Discussion Questions

Before the Game

What is a linear function? In the equation y = mx + b, what are do "m" and "b" stand for? How can you find the slope of a line? What is the slope of a horizontal or vertical line? What is meant by rate of change? What does the slope of a line tell us about the values and rate of change? How do we express the slope of a line that is completely vertical?

After the Game

How do we calculate the slope of a function? What is the y-intercept and what does it represent? What does a graph with a positive slope look like? What does a graph with a negative slope look like? What other real-life examples can be expressed by linear functions? CHALLENGE: The water level of a river is 34 feet, and is receding at a rate of 0.5 foot per day - in how many days will the water reach 26 feet?
