Review 6.EE.1, 6.EE.2, 6.EE.3, and 6.EE.4 - Section 3: Closure + Homework

Instead of giving this study guide out the day before the exam and in conjunction with some parent feedback, I decided to give this study guide out the week (5 days) before the test. Students were instructed to do the problems they could and hold off on any of the problems they were unable to do because they hadn't received the instruction yet. Now, you may think this is a bit crazy, but here's the good part. Students have time to work on the study guide. They have time to ask you about questions they don't understand. They are learning to budget their time by being responsible for their own learning and understanding. They no longer cram for the test the day before. It really does teach them good study skills. Kids ask for extra practice on problems they don't understand. Generally, I send them to Buzzmath. This website is free if you(teacher) set up an account. It is aligned to common core.

Furthermore, students need feedback on whether or not they are working out the problem correctly. So, I created a video tutorial that goes along with the study guide. I put this video on youtube and on Edmodo. Students can then watch the video to check to see that they are working out the problems correctly. Now, you may say that the students will just mark down answers. To that I say, in order for them to get the answers, they had to listen to the video. They heard something. It's still processing.

# Review 6.EE.1, 6.EE.2, 6.EE.3, and 6.EE.4

Lesson 12 of 14

## Objective: SWBAT write and evaluate expressions while reviewing for a test.

*90 minutes*

#### DO NOW

*20 min*

The do now is a problem that has the students determining values that grow in a square area relationship and then explaining how to find these values and extending the pattern. I liked this problem because the students will get to implement **SMP 3** by critiquing other’s work. It also supporst **SMP 4 **because the students will be modeling their solution with an expression.

In this problem, students will be looking at the triangles and making a generalization about the pattern. **(SMP 7 and 8)** They can make a table to help support their answer. Students should conclude that if you square the pattern number it will result in the amount of triangles in the pattern. The expression could look something like this T = p².

#### Problem Solving Review

*60 min*

The students will be working on 2 problem solving questions. The answers to these questions are not within reach. They will need to make sense of the problem (SMP 1) to understand what they are being asked to do . Students should work independently on each problem. I’m going to use 30 minutes for each problem. 15 minutes should be used for independent work and the other 15 minutes, students should share strategies with their table mates. After each problem, do a whole class discussion on solutions and strategies.

Problem 1

Digging Dinosaurs

The students will be looking at writing different expressions by determining the best rate plan to visit a museum when given a number of rate plans which have changed in both cost and time. The students will need to decide which is the plan that will save them the most money and consider whether another plan may be better depending on different criteria.

This problem supports 6.EE.2b where students identify parts of an expression using mathematical terms and 6.EE.2 evaluating expressions.

I chose this problem because this directly correlates with our unit of study. The problem is just beyond reach where an answer is not readily available. This problem supports **SMP 2** because the students need to find the important information to decide what the numbers are telling them. Additionally, it supports **SMP 4** because the students will be writing out the expressions to help them find a solution.

I love this problem because there are a lot of ways to solve and a lot of assumptions to be made. Let students play around with the numbers. It will be interesting to see their take on what they best value would be. The only parameters that are set by the problem is that it is for 2 people and they want to visit the museum 8 times over a 3 month period.

Problem 2: Boxes

Students will be looking at equivalent expressions in this activity. They have to determine which box is the heaviest by looking at scales. Some students may not have any background knowledge on how these scales work so it might be a good idea to explain what the scales are used for and how they measure items.

This problem supports 6.EE.4 identifying when 2 expressions are the same no matter what the value of the variable. It also supports **SMP 3** as students will need to justify their answers and **SMP 7** as students will be explain why it happens this way.

As students work through the problem, they should reason that box 4,5, or 6 is the heaviest box. As they move through more of the scales, students should see that box 6 is the heaviest and be able to explain that 4 and 5 weigh the same, therefore 6 is the heaviest.

#### Closure + Homework

*10 min*

The students will get their study guide to continue to prepare for tomorrow’s assessment. Hand out the study guide and allow students time to look over each problem. Ask students if there is anything on the study guide that they feel may give them difficulty? Give guidance to students as to where they can look for help or what notes section they should use to help them study. If time permits, let students get started on their study guide. Students should be well prepared for this assessment. They have taken notes in prior lessons and used problem solving strategies today to help them prepare. We will go over the study guide prior to the assessment.

Tools: Study guide expressions.
