Slippery Slope - Unit Plan

Slippery Slope - Unit Plan

View full details

Grades 6-8 | 10 (45 min) Classes

In this unit students will answer the question: How is slope represented in a model rocket launch?

Students will learn about the different types of slope and practice calculation methods to find slope from a graph. Students will then analyze launch data to identify and calculate where a rocket has a positive, negative and/or neutral slope on its flight path.

For their final assessment students will be creating a visual of the four types of slope that shows how slope is seen on a model rocket’s flight path.


Common Core Standards - Math



Recognize and represent proportional relationships between quantities.


Decide whether two quantities are in a proportional relationship.


Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. 



Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).


Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.


Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

High School


For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship


Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
