How do you know it is equivalent? What is the same? How do you know? Give the Formative Assessment on a day prior to the lesson. Provide review and remediation as needed. Please see the Further Recommendations for worksheets to practice writing math expressions that represent verbal phrases. Bellwork Warmup activity : Post the following situation on the board or document camera and ask the students to represent it mathematically. You are going to purchase a gift for each of four friends. Each gift will cost the same amount of money. Represent this situation as an inequality, an equation or as an expression. Hopefully, you will get multiple correct solutions from your students. Observe their answers and ask several with different solutions to post them on the board. Do not comment on whether the students are correct or not. You will start the lesson by establishing that there are different ways to represent a math situation. Encouraging the students to be flexible in their thinking will promote reasoning. Pause to allow thinking. Let the students debate the answer but come to the conclusion that they are all different representations of the same situation. Point out to the students that being able to represent a math situation in different ways can be very useful. There will be many times when it can make the math easier or simpler to compute. In order for students to meet this standard, they need to reason about the quantities in equations and how they are related. Some experts call this Relational Thinking. With a bit of drama, tell the students there is magic in the air in math today. Post this equation on the board and tell the students you can figure out the missing number without having to find the sum of 4. You are looking for students who think about the whole equation and the relationship between the parts. If a student does this, be sure to point it out to all students. If no student can do this, you can give the following explanation: You are adding, so both totals must be the same. This is a part to whole relationship. You can take from one part and give it to the other part and the total will not change property of equality. This allows you to find the missing number. So, 5 is the missing number. No, it's being strategic. It's thinking about the relationships within the complete equation before doing anything. ÷ 4 Use the Guiding Questions to help students think about the complete equation. Allow students to fill in what number is the question mark. Ask the students to find the answer without finding the answer to 12. No, just reasoning mathematically by looking for relationships in the equation. Use the Illustrative Mathematics task as the Guided Practice. You will want to click on the PDF link, then copy each part onto separate PowerPoint slides and project each part separately on your computer and projector. You could also print out the PDF and show each part under the document camera. Or, you could print the task for the students. I prefer working then discussing each part at a time. Ask the students to answer one part then discuss this as a class. After about 2 minutes of independent thinking, you could have partners discuss and solve each part together. Please read the commentary section on the PDF for possible solutions and discussion. Use the Guiding Questions to facilitate a discussion about each part of this task. Students will receive a worksheet. This worksheet could be completed in class or just started in class to ensure that students are confident enough to complete it. Students might then complete this at home. Beginning the worksheet in class will allow those students that require assistance to receive individual attention. Be sure to ask those relational questions, such as how expressions are the same and different. I, often, walk the classroom with a clipboard that has questions to be asked on it so I remember what questions to ask. I also use the clipboard to make notes on student performances. Discuss the answers to the worksheet. Since you are trying to build the ability to reason, constantly use the Guiding Questions to deepen this conversation. Summarize by asking students what key ideas they should have learned from this lesson. Administer the Summative Assessment when you believe the students are ready. Please see the Summative Assessment section. First, you will find review worksheets for students who need more help with the ability to translate verbal phrases into algebraic expressions. Many of our students need this practice even though it is a 6th grade standard. These worksheets are found in the Further Recommendations section. Second, the heart of this lesson will focus on the intent of this standard to help students develop relational thinking using equivalent expressions. Please consider the ability of your students and use the materials best suited for them. On a day prior to the lesson, give the students the attached Formative Assessment. If any student does not show mastery of this prior knowledge, you will want to work with them in small groups before this lesson. The Guiding Questions are good examples for these questions. Students should be able to identify and utilize the commutative, associative and distributive properties as well as identify equivalent expressions. Feedback should be ongoing as you respond to the students' questions and answers. Encourage students to answer all questions that are presented and redirect questions when applicable to ensure students understand equivalencies. If students begin to solve equations without looking at the complete equation and searching for a way to make equivalence, strongly encourage them to stop sit on their hands, if needed and reason first. Tell them this is being strategic. Find another maybe simpler or easier way to solve the challenge without doing all of the calculations. Help them understand we are trying to build their ability to reason, not just do calculations. Circulate as students are doing individual work, ensuring all work is scanned for accuracy. This is a great time for individual attention if needed. Use the Guiding Questions to probe and clarify student thinking.

Students will review utilizing an activity with five different colors of cardstock. Remind students that this lesson will continue to build on what was learned during their 6th grade year. Have a set of volunteers come to the front of the classroom. Ask students if this can be expressed in a different way. Students should recognize that this problem can be expressed as -6x + 9. Here are worksheets to practice the skill of representing verbal phrases with algebraic expressions.
What are variables, expressions, and equations?
Key to Geometry workbooks introduce students to a wide range of geometric discoveries as they do pan-by-step constructions. Simplifying Variables Worksheets This Simplifying Variables Worksheet will create algebraic statements for the student to simplify. Help them understand we are trying to build their ability to reason, not just do calculations. Feedback should be ongoing as you respond to the students' questions and answers. They can then prime the equations to determine the sea level change for a specified number of years in those areas. Have pairs discuss and then share their thoughts with the class.

Then have them discuss in pairs why the number of bags used is the independent variable and why the total tax charged is the dependent variable. ÷ 4 Use the Guiding Questions to help students think about the complete equation. Note: Unlike most resources on HelpingWithMath. You are piece to purchase a gift for each of four friends.
