Percent Models Test - Section 3: Summary

In each of my blocks, I had students work right up to the end of class, so I did not have time for the summary activity. (Before I start a test I always ask if there are any more questions or problems they want to try before we take the test, and in all classes students asked for a couple more examples before the test - so that ate into my summary time.)

That being said, since I had ample time to correct while students tested, I was able to give out scores before students went home. The kids did awesome! My class averages for the three blocks were 96.1, 94, and 98.3. As I mentioned before, I have never approached percents this way - but I ALWAYS will from now on. One of the biggest issues I have had in the past is kids not knowing when to add or subtract (tax or discount) - but using the models that did not seem to cause an issue at all. The few mistakes that students did make were not on the mark up/down part, but rather breaking up the number into ten parts and counting them up correctly. I am so excited to move to problems next week using the calculator because I really think kids have a good foundation of what percent looks like.

# Percent Models Test

Lesson 5 of 21

## Objective: Students will be able to solve a variety of percent application problems using a percent bar model.

## Big Idea: See the fruits of your labor! Do they get it? This short 8 question assessment will give you insight into your students' understanding.

**Opener: **As students enter the room, they will immediately pick up and begin working on the opener – Instructional Strategy - Process for openers. This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is **mathematical practice 3**.

**Learning Target: **After completion of the opener, I will address the day’s learning targets to the students. For today’s lesson, the intended target is, “I can solve a variety of percent problems using a percent bar model.” Students will jot the learning target down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

**Thoughts from Me! **As a way to dive into percents and create a conceptual understanding, students will utilize a bar model (**mathematical practice 5**). They will use the model to represent scenarios conceptually (**mathematical practice 4**) instead of just punching numbers. Students will also reason abstractly and quantitatively by analyzing what each model represents (**mathematical practice 2**). Students will look for repeated reasoning to make connections within percents (**mathematical practice 8**).

#### Summary

*5 min*

**Instructional Strategy - Table Discussion: **To summarize this lesson, I will have students have a table discussion on: How are we going to solve harder problems like finding 18.75% of 53. Up until now, I have used all examples where students could easily breakdown the numbers and use a model, moving forward, students are going to need to come up with mathematical operations that will allow them to do the same thing that as a model. I am simply going to have students discuss this problem, I am not going to share right or wrong answers – I want them to leave my class thinking!
