__7.EE.B.3 Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 110 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 934 inches long in the center of a door that is 2712inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.__

**Objective:**__: What are the main differences between the types of equations?__

**Essential Question****I Can**understand the similarities and differences between the two main types of equations we are studying in this unit. When I have a situation or a tape diagram, I can represent it with an equation.

Today's Agenda:

- Quiz
- More Open Middle Tasks

## Tuesday: 3/6/18

__7.EE.B.4.a Solve word problems leading to equations of the form px+q=rand p(x+q)=r, where p, q, and rare specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?__

**Objective:**__: How does a hanger diagram relate to an equation?__

**Essential Question****I Can**find an unknown weight on a hanger diagram and solve an equation that represents the diagram. I can write an equation that describes the weights on a balanced hanger. I can explain how a balanced hanger and an equation represent the same situation.

**Objective:**__: How can we used balanced hangers to solve equations?__

**Essential Question****I Can**explain why some balanced hangers can be described by two different equations, one with parentheses and one without. I can explain how a balanced hanger and an equation represent the same situation. I can write an equation that describes the weights on a balanced hanger.

I can find an unknown weight on a hanger diagram and solve an equation that represents the diagram.

Today's Agenda:

- Reasoning about solving equations (part 2)
- Practice Problems - video

## Thursday: 3/8/18

__7.EE.B.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. 7.EE.B.4.a Solve word problems leading to equations of the form px+q=rand p(x+q)=r, where p, q, and rare specific rational numbers.

**Objective:**__: How do we solve equations with negative numbers__

**Essential Question****I Can**I can use the idea of doing the same to each side to solve equations that have negative numbers or solutions.

Today's Agenda:

- Add the lesson summary from yesterday's lesson - video
- Dealing with negative numbers
- Modeling more equations with tape diagrams or hangar balances (with the file linked below)

Dear CC7 Students,

Hello! Unfortunately, I cannot be with you today. You are expected to get started RIGHT away when the bell rings at the beginning of the period . Remember, I expect you to be working and not socializing during this time. This is an academic setting, one in which I am holding you accountable for. Please be sure you have chosen your seats where you will work best.

Please be sure you have chosen your seats where you will work best.

- Go to today’s daily agenda. Watch the video I have made explaining the project you are to complete. You will have a LIMITED amount of time to work on it on Monday.
- IF you have remaining time, work on IXL 7th grade R1- R6. Completing with a minimum of 80% accuracy on a section before moving on.
