7th Math Unit 1 Day 6 - 9/6 - Admin Espinoza | Library

Objective and Summary:
SWBAT decide whether two quantities are proportional by graphing on a coordinate plane and observing for a straight line through the origin

1

Refresh--What are the two traits that we look for in a graph to tell if it represents a proportional relationship?

Select all that apply.

Sale—The school library receives money for every book sold at the school’s book fair.

Is there a proportional relationship between number of books and the total cost? Graph, then explain using evidence from your graph.

CFS
#1: Accurately graphs ordered pairs
#2: Justifies using appropriate evidence and vocabulary from graph

Ice Cream--At Cold Stone, you get the first two toppings for your ice cream cone-free. The rest of the prices are in the table below:

Is there a proportional relationship between number of toppings and the total cost? Graph, then explain using evidence from your graph.

Roadtrip--Mr. Pham has a hybrid car and is going camping with his family. The hours they spend driving and the gallons of gas left in the tank are shown in the table.

Is there a proportional relationship? Graph, then explain using evidence from your graph.

Pick and Choose--Using only the shape of the graphs, decide if you agree with the following statement:

"The two graphs pictured represent proportional relationships."

Mix and Match--Three graphs are shown below. Click and drag the blue arrows of each graph into either the "Proportional" or "Non-proportional" labels.

Graph 1
Graph 2
Graph 3
Graph 4

Proportional
Non-proportional

Justify--How do you know the graphs are proportional or non-proportional? Explain for EACH graph and refer to them as Graph 1, Graph 2, Graph 3, or Graph 4.

"I know Graph 1 is (proportional / not proportional) because..."
