Activity Synthesis
Ask several student to share which expressions they chose for the second question. Discuss until everyone is in agreement about the answer to the second question.
7.2: Phone Inventory (10 minutes)
- MLR8: Discussion Supports
Positive and negative numbers are often used to represent changes in a quantity. An increase in the quantity is positive, and a decrease in the quantity is negative. In this activity, students see an example of this convention and are asked to make sense of it in the given context.
Arrange students in groups of 2. Give students 30 seconds of quiet work time followed by 1 minute of partner discussion for the first two problems. Briefly, ensure everyone agrees on the interpretation of positive and negative numbers in this context, and then invite students to finish the rest of the questions individually. Follow with whole-class discussion.
A store tracks the number of cell phones it has in stock and how many phones it sells.
The table shows the inventory for one phone model at the beginning of each day last week. The inventory changes when they sell phones or get shipments of phones into the store.
- What do you think it means when the change is positive? Negative?
- What do you think it means when the inventory is positive? Negative?
- Based on the information in the table, what do you think the inventory will be at on Saturday morning? Explain your reasoning.
- What is the difference between the greatest inventory and the least inventory?
Tell students that we often use positive and negative to represent changes in a quantity. Typically, an increase in the quantity is positive, and a decrease in the quantity is negative.
Ask students what they answered for the second question and record their responses. Highlight one or two that describe the situation clearly.
Ask a few students to share their answer to the third question, and discuss any differences. Then discuss the answer to the last question.
7.3: Solar Power (15 minutes)
- Anticipate, Monitor, Select, Sequence, Connect
- MLR6: Three Reads
It is common to use positive numbers to represent credit and negative numbers to represent debts on a bill. This task introduces students to this convention and asks them to solve addition and subtraction questions in that context. Note that whether a number should be positive or negative is often a choice, which means one must be very clear about explaining the interpretation of a signed number in a particular context (MP6).
For the second question, monitor for students who find the amount each week and sum those, and students who sum the value of the electricity used and the value of the electricity generated separately, and then find the sum of those.
Arrange students in groups of 2. Give students 4 minutes of quiet work time followed by partner discussion. Follow with a whole-class discussion.
Han's family got a solar panel. Each month they get a credit to their account for the electricity that is generated by the solar panel. The credit they receive varies based on how sunny it is.

Ask one or more students to share their answer to the first question and resolve any discrepancies.
Ask selected students to share their reasoning for the second questions. Discuss the relative merits of different approaches to solving the problem.
Finish by going over the solution to the third question. Point out that the bill will reflect a negative number in the amount due section, but we can interpret this to mean that the family receives a credit, and it will be applied to their next bill.
7.4: Differences and Distances (15 minutes)
Optional activity.
In grade 6, students practiced finding the horizontal or vertical distance between points on a coordinate plane. In this activity, students see that this can be done by subtracting the \(x\) or \(y\) -coordinates for the points (MP7). Students continue to work with the distinction between distance (which is unsigned) and difference (which is signed) (MP6). This prepares them finding the slope of a line and the diagonal distance between points in grade 8.
Arrange students in groups of 2. Give students 3 minutes of quiet work time followed by partner discussion. Follow with a whole-class discussion.
Plot these points on the coordinate grid: \(A= (5, 4), B= (5, \text-2), C= (\text-3, \text-2), D= (\text-3, 4)\)
- What shape is made if you connect the dots in order?
- What are the side lengths of figure \(ABCD\) ?
- What is the difference between the \(x\) -coordinates of \(B\) and \(C\) ?
- What is the difference between the \(x\) -coordinates of \(C\) and \(B\) ?
How do the differences of the coordinates relate to the distances between the points?
Plot these points on the coordinate grid: \(A= (5, 4), B= (5, \text-2), C= (\text-3, \text-2), D= (\text-3, 4)\)

Main learning points:
When two points in the coordinate plane lie on a horizontal line, you can find the distance between them by subtracting their \(x\) -coordinates.
When two points in the coordinate plane lie on a vertical line, you can find the distance between them by subtracting their \(y\) -coordinates.
- The distance between two numbers is independent of the order, but the difference depends on the order.
Discussion questions:
- Explain what makes the distance between two points and the difference between two points distinct.
- Explain how you would find the vertical or horizontal distance between two points.
- Explain how you would find the vertical or horizontal difference between two points.
Lesson Synthesis
What are some situations where adding and subtracting rational numbers can help us solve problems?

Student Lesson Summary
Sometimes we use positive and negative numbers to represent quantities in context. Here are some contexts we have studied that can be represented with positive and negative numbers:
- temperature
- an account balance
- electricity flowing in and flowing out
In these situations, using positive and negative numbers, and operations on positive and negative numbers, helps us understand and analyze them. To solve problems in these situations, we just have to understand what it means when the quantity is positive, when it is negative, and what it means to add and subtract them.

Scientists, engineers, and ordinary people use problem solving each day to work out solutions to various problems. Using a systematic and iterative procedure to solve a problem is efficient and provides a logical flow of knowledge and progress.
In this unit, we use what is called "The Technological Method of Problem Solving." This is a seven-step procedure that is highly iterative—you may go back and forth among the listed steps, and may not always follow them in order. Remember that in most engineering projects, more than one good answer exists. The goal is to get to the best solution for a given problem. Following the lesson conduct the associated activities Egg Drop and Solving Energy Problems for students to employ problem solving methods and techniques.
Lesson Background and Concepts for Teachers
The overall concept that is important in this lesson is: Using a standard method or procedure to solve problems makes the process easier and more effective.
![1) Describe the problem, 2) describe the results you want, 3) gather information, 4) think of solutions, 5) choose the best solution, 6) implement the solution, 7) evaluate results and make necessary changes. Reenter the design spiral at any step to revise as necessary. 1) Describe the problem, 2) describe the results you want, 3) gather information, 4) think of solutions, 5) choose the best solution, 6) implement the solution, 7) evaluate results and make necessary changes. Reenter the design spiral at any step to revise as necessary.](https://www.teachengineering.org/content/cla_/lessons/cla_lesson2_problem_solving/problem_spiral_lesson2_image1.jpg)
The specific process of problem solving used in this unit was adapted from an eighth-grade technology textbook written for New York State standard technology curriculum. The process is shown in Figure 1, with details included below. The spiral shape shows that this is an iterative, not linear, process. The process can skip ahead (for example, build a model early in the process to test a proof of concept) and go backwards (learn more about the problem or potential solutions if early ideas do not work well).
This process provides a reference that can be reiterated throughout the unit as students learn new material or ideas that are relevant to the completion of their unit projects.
Brainstorming about what we know about a problem or project and what we need to find out to move forward in a project is often a good starting point when faced with a new problem. This type of questioning provides a basis and relevance that is useful in other energy science and technology units. In this unit, the general problem that is addressed is the fact that Americans use a lot of energy, with the consequences that we have a dwindling supply of fossil fuels, and we are emitting a lot of carbon dioxide and other air pollutants. The specific project that students are assigned to address is an aspect of this problem that requires them to identify an action they can take in their own live to reduce their overall energy (or fossil fuel) consumption.
The Seven Steps of Problem Solving
1. Identify the problem
Clearly state the problem. (Short, sweet and to the point. This is the "big picture" problem, not the specific project you have been assigned.)
2. Establish what you want to achieve
- Completion of a specific project that will help to solve the overall problem.
- In one sentence answer the following question: How will I know I've completed this project?
- List criteria and constraints: Criteria are things you want the solution to have. Constraints are limitations, sometimes called specifications, or restrictions that should be part of the solution. They could be the type of materials, the size or weight the solution must meet, the specific tools or machines you have available, time you have to complete the task and cost of construction or materials.
3. Gather information and research
- Research is sometimes needed both to better understand the problem itself as well as possible solutions.
- Don't reinvent the wheel – looking at other solutions can lead to better solutions.
- Use past experiences.
4. Brainstorm possible solutions
List and/or sketch (as appropriate) as many solutions as you can think of.
5. Choose the best solution
Evaluate solution by: 1) Comparing possible solution against constraints and criteria 2) Making trade-offs to identify "best."
6. Implement the solution
- Develop plans that include (as required): drawings with measurements, details of construction, construction procedure.
- Define tasks and resources necessary for implementation.
- Implement actual plan as appropriate for your particular project.
7. Test and evaluate the solution
- Compare the solution against the criteria and constraints.
- Define how you might modify the solution for different or better results.
- Egg Drop - Use this demonstration or activity to introduce and use the problem solving method. Encourages creative design.
- Solving Energy Problems - Unit project is assigned and students begin with problem solving techniques to begin to address project. Mostly they learn that they do not know enough yet to solve the problem.
- Energy Projects - Students use what they learned about energy systems to create a project related to identifying and carrying out a personal change to reduce energy consumption.
The results of the problem solving activity provide a basis for the entire semester project. Collect and review the worksheets to make sure that students are started on the right track.
