7th Math Unit 1 Day 5 - 9/5

Mr. Espinoza does not like to go running. Instead, the table shows his walking pace.

a. Is this still proportional?

Check with the table and by graphing, then explain using 2 different strategies

Still Running--Mr. Hernandez loves to run, and his running pace is shown below.

Graph the coordinate pairs. Is this a proportional relationship? Use evidence from the table AND the graph.

#1: Accurately computes unit rates

#2: Explains using appropriate evidence from tables and graphs

Takis are Back!--Back at Ms. P's Place, Takis are sold for the following prices:

Graph the coordinate pairs.

Life Savings--Andrea is plotting how much money she has in her bank account over time. She starts with $30 and every week she saves $5 more.

Is the following statement true or false?

"Using only the graph, Student McStudentson can tell that this is a proportional relationship because it is a straight line."

BE CREATIVE--Create your own table and graph that shows a relationship that is NOT proportional.

Make sure to...

1) Write out a word problem

2) Complete the table

3) Complete the graph and explain why it is not proportional.

Berry Picking—The following table gives the number of people picking strawberries in a field and the corresponding number of hours worked by each person.
