Reflection: Data Analysis Problem Solving Connections - Can you apply what you know about proportional reasoning? - Section 2: Explore


For some very odd reason, the biggest misconception I encountered was students deciding to calculate the unit rate and then multiply it by ten?!  I sat with one group, and when I asked why they multiplied by ten, they said because 4 miles per hour didn't sound fast - well, then it hit me, they were trying to make the unit rate into miles per hour - but really it was given to them in miles per minute! I was concerned going into the lesson that I was going to have to walk them through it, but I was pleasantly surprised.  I partnered the kids homogeneously and they were able to dive right in. 


I have stuck with the kids not being able to use calculators, and it has been really helpful I think in tweaking their skills with rational numbers.  Instead of freaking out that the table consisted of fractions, they just got to work :)

Problem Solving Connections - Can you apply what you know about proportional reasoning?

Unit 2: Proportional Reasoning
Lesson 10 of 14

Objective: Students will be able to apply aspects of proportional reasoning including unit rates, graphs, tables, and equations to work a real world problem.

Big Idea: If it doesn't apply, I don't care - heard that before? Well, this lesson applies what students have learned about proportional reasoning!
