LESSON OVERVIEW Summary of the task, challenge, investigation, career-related scenario, problem, or community link.

The main focus of these lessons will be for students to work in small groups and take turns in a leadership role practicing leadership skills learned in all content areas. Students will review two pre-algebra skills: combining like terms and order of operations. Then they will solve equations from one-step to multi-step, often involving STEM applications. The unit concludes with students learning to solve multi-step inequalities and compound inequalities.

Students will use inequalities on the Solar Oven Project by staying within the given budget for purchasing materials and by cooking the food in solar oven design # 2 in a time less than the cooking time of the first prototype. In the Dock the Rock project students will set up a compound inequality showing the distance their vessel sails falls between the sailing times of two other teams’ vessels (of course, min/max times will not be written as compound inequalities).

MOTIVATOR Hook for the week unit or supplemental resources used throughout the week. (PBL scenarios, video clips, websites, literature)

Appendix B

“Teacher

Notes,”

Appendix C

Large sheets of paper titled with the different sets of numbers: integers, real numbers, natural numbers, whole numbers,

Essential Question: How do I Classify numbers by type?

Activating Strategy: Teacher will show the comic with pi and i. Pi says

“get real” and I says “be rational”. This is just a lead in to a discussion on types or sets of numbers.

Teaching Strategy: Talk to students about how people are classified.

“The president might also be a father, husband, and lawyer but he will be a called the president. This is the most specific way to describe him.”

Use other examples from sports or pop culture.

Show students the “Number sets diagram.” Using the “Teacher

Scripted Notes” discuss the different number sets with the class. Using

Frayer diagrams is suggested to give definitions, characteristics, examples, and non-examples of each type of number.

Summarizing Strategy: Give students index cards with various numbers on them. Students will walk around the room writing the number on their index card on each and every sheet titled with a set to which the number belongs. For example, if the square root of two is written on the index card, the student will write the square root of two on the sheets of paper titled “Real” and “Irrational.” The sheets of large paper

The numbers students will be classifying can be varied for enrichment or remediation:

Remediation

Use 0, 46, -213, 4/5, and 8.9.

These are classic examples and do not require more than the basic understanding so that students can experience success and gain confidence.

Enrichment

Use the square root of four,

8.161161116…, 5-7i. These require critical thinking to classify.

Appendix B can be used to initiate review on the following day.

Essential Question: How do I simplify an expression using the order of operations?

Activating Strategy: Put a complex numerical problem on the board that is commonly confused using order of operations. Ask students to simplify the expression. Students should get several different answers.

Have several students explain how they arrived at an answer. Talk about

Laws and how they create order (order of operations) and leadership.

Teaching Strategy: Teacher will use the acronym PEMDAS as a memory tool for the correct order of operations. Make sure that students understand the multiply and divide must be done at the same time from the left to the right. Add and subtract must be done at the same time from left to right. Use examples (See Appendix A) that illustrate that it does matter! Many students will have been taught incorrectly somewhere along the way (multiply, then divide, add, then subtract). It takes really stressing this point for students to unlearn the incorrect procedure. Some whole group examples, partner problems, and individual practice will be included in the lesson.

Students will then work in groups to create and solve expressions from real-world examples. For example, students could say that the football team gained 6 yards, then lost 5, then gained twice as much as they gained on the first play. Students will be assigned groups and group roles. They will take turns as the leader of the group to practice writing and simplifying expressions. Because the real-world examples may be more simplistic in nature, students should also create some more challenging problems that do not need to be tied to an application.

Essential Question: How do I communicate my mathematical reasoning through tables, pictures, and words?

Activating Strategy:

Students will be given a couple of word problems to solve on their own,

“Examples for Lesson Motivator.”

Teaching Strategy:

Hand out “Building with Square Tiles” sheet and square tiles. Read through the scenario and clarify any uncertainties. Model for students how to use the T-Chart for problem solving (what I know/ what I need to know).

Let students start the problem individually. After allowing students to answer the questions on their own for a few minutes, bring the class together to discuss how things are going. Remind students during this time NOT TO GIVE AWAY THE ANSWER. This is a time students to hear each other’s ideas on how to solve the problem.

After this discussion, students will work in their table groups to complete the task. Rolls will be assigned. They will work to task completion.

Summarizing Strategy:

Teaching Strategy: Start with a discussion about “undoing” things, like apologizing “undoes” being sassy. Putting money in the checking account “undoes” being overdrawn. Discuss specific mathematical operations that “undo” other mathematical operations. Subtraction

“undoes” addition, etc.

Do some whole class practice, small group or partner practice and individual practice problems (see Appendix A for “Examples for Lesson with Answer Key”).

Summarize: Ticket Out the Door—Write an equation to fit a word problem and explain in several sentences how you created this equation and the step you would take to solve the problem.

Activating Strategy: Bring to class a small safe or cage containing a ball, collector card, or piece of candy (something in which the students will have an interest). Put the safe inside a bag or put a brick on top of the locking mechanism. This is to illustrate that you must eliminate the outer obstacle first, then the obstacle closest to the object of desire.

Teaching Strategy: Talk about getting dressed versus getting undressed.

Whatever you put on last must come off first, etc. Choose sample equations that require division by -1 and multiplication by the reciprocal of a fraction, amongst other two-step equations.

Do some whole class practice, small group or partner practice and individual practice problems using “Two-Step Equations with Answer

Key.”

Continue working in groups and stress the importance of leadership.

Use Properties Labels (Distributive, Commutative, reflexive, addition, multiplication, etc.) at the board when solving equations. Pass out student sets so that students can give reasons for steps when solving equations.

Achieved by allowing students extra practice with one-step equations. They should complete “One-Step

Equations.”

Enrichment

Can be given through problems with fractions and decimals.

Lesson: There will be no new notes today. We will go immediately into the example problems. Choose problems that are different from one another from “Solving Multi Step Equations 2.”

Do some whole class practice, small group or partner practice and individual practice problems with the remaining problems on “Solving

Multi Step Equations 2.”

Summarize: Have partners begin working on the assignment “Solving

Multi Step Equations 1” (homework). One partner will solve the equation and the other will label with the appropriate property. Finish overnight.

Remediation
