1Creating a Transition CCSSM Unit Example of a unit on expressions and equationsSVMI
2Think in Terms of UnitsPhil Daro has suggested that it is not the lesson or activity, but rather the unit that is the “optimal grain-size for the learning of mathematics”. Hence that was the starting point for our Scope and Sequence.Developers of High School: Patrick Callahan, Dick Stanley, David Foster, Brad Findell,Phil Daro, and Marge Cappo
3New K-12 Math Curriculum Inspired by The Common Core State Standards The Gates Foundation and the Pearson Foundation are funding a large scale project to create a system of courses to support the ELA and Mathematics CCSS. These will be a modular, electronic curriculum spanning all grade levels. A Santa Cruz based company, Learning In Motion, is working to write the lessons.

7The Big Idea of the UnitThe seventh grade unit “Expressions and Equations” addresses the mathematical concepts of variables, expressions and equations. Students learn that variables can represent unknown quantities. An algebraic expression is a generalization of number(s), operation(s) and/or variable(s) that represents one or more quantities. An algebraic equation is a statement that indicates two expressions are equal. Students represent real situations or mathematical relationships with expressions and equations. Students solve equations using mathematical methods such as, guess and check, using tables, graphs, deductive reasoning, and algebraic methods. Student use properties of operations to change expressions and equations into different forms. They model real life situations with expressions and equations. Algebraic methods of solving equations are learned and applied to everyday and mathematical situations.

13Math Talks Math Talks are used to: • A daily ritual with the entire class for the purpose of developing conceptual understanding of and efficiency with numbers, operations and other mathematics such as geometry and algebra. (no more than 10 minutes per day)Math Talks are used to:• Support active student engagement through signaling• Review and practice procedures and concepts• Introduce a concept before diving into the lesson of the day• Support students in deepening their understanding of the Properties of Arithmetic and our Place Value System• Explore mathematical connections and relationships• Encourage students to construct viable arguments and critique the reasoning of others• Support students in using precise mathematical language in sharing their different strategies and approaches
14Math TalkIf the lime and cherries are single digits, what are their values?
15Math TalkIf the grape is a single digit, what values could the grape be?
16Math TalkIf the plum and orange are single digits What are their values?

18Problems of the MonthA program to foster school-wide participation in math and problem solving.
19CCSS Mathematical Practices REASONING AND EXPLAINING2. Reason abstractly and quantitatively3. Construct viable arguments and critique the reasoning of othersOVERARCHING HABITS OF MIND1. Make sense of problems and persevere in solving them6. Attend to precisionMODELING AND USING TOOLS4. Model with mathematics5. Use appropriate tools strategicallySEEING STRUCTURE AND GENERALIZING7. Look for and make use of structure8. Look for and express regularity in repeated reasoning
20How are the POM be used?The POM are used school wide to promote problem solving.Each problem is divided into five levels, A-E, to meet the learning development needs of all students.A great tool for Differentiated Instruction.Students, teachers and parents learn to ask questions and persevere in solving non-routine problems.The whole school celebrates doing mathematics at school.
21It’s better to solve one problem five different ways than to solve five different problems. George Polya
27“A problem is not a problem if you can solve it in 24 hours.” George Polya
28Creating a PosterYour concluding thoughts on an explanation poster for a level you feel you have completedANDYour current thoughts on a status poster for a level you are still exploring.
29Explanation Poster: The focus of your poster should be on how your findings can be justified mathematically and how your findings make sense. Include words and visuals (such as drawings) as a part of your justification.Status Poster: The focus of your poster should be on your processes so far and where you think you want to go next and/or questions/wonderings you have about this level. Include words and visuals as a part of your justification.*Remember to justify or explain your processes you have used so far and why they make mathematical sense as clearly as you can.
30Gallery Walk Each group will display their poster. Each group selects a group member to be the docent to answer questions or provide clarifications/explanations.The other group members examines, explores, reviews the other groups’ posters.There will be time for your group to re-assemble and discuss the information shared in the groups’ posters.Please mind gallery walk norms and be respectful of the work and information shared.Share the organizing schemes in a gallery walk (whole group gallery walk – 10 minutes)Whole group reflecting on findings from gallery walk (whole group – 8 minutes)

38Writing Algebraic Expressions Which two expressions are equivalent?
39Which Equations Describe The Story? A pencil costs $2 less than a notebook.A pen costs 3 times as much as a pencil.The pen costs $9Which of the four equations opposite describe this story?Let x represent the cost of notebook.
40Writing Equations To Describe A Story? Write an equation for Story 1 (S-1).Let x represent the number you are trying to find.(Solo, Partner, Class)
41Writing Equations To Describe A Story? Write equations for Stories 2-6 (S-2S-6).Let x represent the number you are trying to find.Individual Think TimePartner Talk
42Matching Stories and Equations Work together to match each story with an equation.Be sure to check to see whether any of the equations you and your partner have written down “match” the equations on the cards.
43Sharing Matched Stories and Equations Docent/Data Collector Protocol Before we begin sharing our work, have one partner write down the agreed upon matches on the dry/erase board.Docent (Remains)Data Collectors (Visits)Discuss, revise, edit, and extend your mathematical thinking to create a Presentation Poster.
45Showing Steps to Solving Equations Material ManagementDivide your construction paper into four quadrants.Glue cards E1 to E4 on the front of your posterGlue cards E5 and E6 on the back of your poster
46Showing Steps to Solving Equations Matching “E1-E4” with “Steps to Solving”Select the steps needed to solve each of the equation cards E1-E4.Write a description of the process involved for each step in solving; e.g., “divide both sides by 2” or “add 6 to both sides”.Do this for each step in the solving process.If you find that there is more than one method for solving an equation, glue the two solutions side-by-side in the appropriate quadrant.Write an explanation to show how you arrived at the equation match to your story situation.
47Showing Steps to Solving Equations Once you’ve finished matching E1-E4, begin showing the steps and justifications for E5 and E6.Write a description of the process involved for each step in solving; e.g., “divide both sides by 2” or “add 6 to both sides”.Do this for each step in the solving process.If you find that there is more than one method for solving an equation, glue the two solutions side-by-side in the appropriate quadrant.Write an explanation to show how you arrived at the equation match to your story situation.
48Follow-Up Lesson Original pre-assessment, “Express Yourself” Carefully look over your original work.Please write about what you have learned since you did this task.“Express Yourself (Re-visited)”Please use what you have learned to answer these questions.
