Reflection: Real World Applications Proportional Reasoning and Percent - Can you apply the concepts? (3 Day Lesson) - Section 2: Explore


I decided to do this type of lesson because I have seen how my students perform on multiple choice tests, but what I wasn't able to determine was whether they could take that knowledge and apply it to a real world situation.  These performance tasks allowed me to do just that.  Since I used the tasks as an assessment of their knowledge, I did not help students at all.  I utilized a mixed homogeneous pairing to form my table groups, thus I knew that everyone at the table could do something, and at least one person could explain everything.  This allowed for multiple entry points for students, and every child felt like they could contribute.

In terms of presentations, once the two groups formed to a larger group, I chose 3-4 people to present.  I made this choice based on the discussions that took place over the two days.  For example, in one group a student was adamant that the two men could mow the lawn in 24 minutes, but it took him almost 15 minutes to explain that to his group.  However, over time he was able to break down his work enough that his group mates bought in to his solution.  I chose him to speak because I knew he would be able to answer questions that arose from the class, if there were any.

Proportional Reasoning and Percent - Can you apply the concepts? (3 Day Lesson)

Unit 3: Percents
Lesson 21 of 21

Objective: Students will apply concepts learned within the proportional reasoning and percent units to solve real world problems.

Big Idea: What's the point of learning it if you can't apply it in the real world? Students will apply concepts learned in the RP strand of the common core to real world problems.
