2 Key Ideas and Details Section I: Alignment to the Standards for Mathematical Practice Algebra I Standard for Mathematical Practice 1: Make sense of problems and persevere in solving them. The PowerTeaching curriculum consistently encourages students to ask questions, plan for solutions, assess their reasoning and the reasonableness of their answers, and to check their work. The students focus on these good habits as a part of the daily PowerTeaching lesson routine as well as specific strategy lessons throughout the curriculum. Team Huddle During daily Team Huddle activities, students work with their teammates to discuss, plan for, and solve math problems. Within the team, they must work through disagreements, ensure that each teammate understands and can explain the solution, and encourage each other when problems seem difficult. Problem Solving Strategies Students practice the various problem-solving strategies at multiple points. Specific lessons introduce and have students practice the strategies: identify extraneous data, make a model, find a pattern, guess and check, work backwards, and solve a simpler problem. Extended Response Many PowerTeaching learning cycles culminate in an extended response lesson. The math problems in these lessons are complex and combine multiple math topics. The teacher modeling, teamwork activities, and individual practice are all centered on solving these real-world problems in steps: understand the problem, find the parts, make a plan, estimate the answer, find the solution, and assess the reasonableness and correctness of the solution. Standard for Mathematical Practice 2: Reason abstractedly and quantitatively. Throughout PowerTeaching students will routinely approach math concepts using both concrete and abstract tools and methods. Problem Solving Strategies The problem solving strategies that students learn help them break apart word problems and real-world math scenarios into the important information, then represent this information as numeric and algebraic models. Problem Solving Practice In each cycle, students will apply the problem solving strategies they have learned. Many lessons include real-world math problems. The students learn to represent the solutions to these problems concretely and abstractly. Students are also routinely asked to design a math story for a numeric or algebraic model. Project-Based Learning The PowerTeaching curriculum includes quarterly project-based learning opportunities. These activities will be multi-day cycles of learning that include planning, research, modeling, reporting, and presenting. Students will be required to represent their project topic mathematically, use the math to find a solution to the problem they researched or an answer to the question they asked, and then explain how the mathematical model relates back to their original problem or question. Standard for Mathematical Practice 3: Construct viable arguments and critique the reasoning of others. Students will support their arguments with sound reasoning as well as critique or support the reasoning of others. They will construct their supports and critiques both in writing as well as verbally. Get the Goof Each lesson includes a Get the Goof activity. Students will discuss a completed problem related to recently studied math topics. They will work with their teams to identify the
3 error in think that led to a mistake in the math work. The students will explain the error and correct the math. Random Reporter A part of the daily PowerTeaching routine includes teamwork and team discussion to solve problems. At various points during each lesson, the teacher will use Random Reporter to have a student from each team share their answer and support that answer with their team s reasoning. Extended Response One type of extended response math problem will have students critique the math reasoning presented in the problem, correctly solve the problem, and construct a viable argument to support their reasoning. These types of extended response situations will represent about one third of the PowerTeaching extended response experiences. Standard for Mathematical Practice 4: Model with mathematics. Students will use tables, graphs, charts and diagrams to represent mathematical information. They will also use number sentences, expressions, and equations to describe a situation. Students will also use the information they gather in tables, graphs, charts, and diagrams to identify patterns, determine relationships, and draw conclusion. Problem Solving Strategy: Modeling Students will receive specific and targeted instruction on modeling as a strategy to solve math problems. Problem Solving Practice The ongoing problem solving experiences, word problems, real-world scenarios, and extended response, often require students to represent the data as a model. Students must determine which model would best help them find the solution or answer the question. Standard for Mathematical Practice 5: Use appropriate tools strategically. Throughout the PowerTeaching curriculum, students will be guided to use various tools to solve math problems and answer math questions. They will also be faced with opportunities to choose which tool would best help them solve more complex math problems or real-world scenarios. The students will more often be faced with choices when completing extended response and project-based learning activities. Standard for Mathematical Practice 6: Attend to precision. Students will use symbols, math vocabulary, and clear explanations in their team discussions and written and oral explanations. Students will also make choices to best represent their solution and reasoning clearly and efficiently. Rubrics Students will use rubrics to assess the completeness and clarity of their oral and written explanations. They will also use the rubrics to critique the explanations of their peers. Complete explanations include the correct answer stated as a complete sentence that identifies the question and a clear explanation in words, as a diagram, using symbols. Vocabulary PowerTeaching key vocabulary is highlighted in each lesson. The definition is built into the lesson instead of only existing in a separate glossary. Students will see the vocabulary used correctly within the teacher modeling and be expected to use key vocabulary to support their mathematical thinking. Standard for Mathematical Practice 7: Look for and make use of structure. Specific targeted skills in the PowerTeaching curriculum address the topics of structure and patterns. Problem Solving Strategy: Look for a Pattern Students will learn to identify problems that can be solved by finding and describing a pattern. They will learn how to represent the data to most efficiently identify the pattern. In later lessons, students will apply this strategy to new and more
4 complex problem solving situations. Expressions and Equations Within the Expressions and Equations content area students will consistently work to make sense of data by defining any patterns they notice and translating those patterns into expressions, equations, and graphs. Formulas and Mathematical Rules In the PowerTeaching curriculum, students will be guided through instruction, modeling, teamwork, and individual practice, to define rules and formulas based on work with multiple examples. Instead of being given the rule, they will have to write the rule, and then prove it by applying it to new situations. Standard for Mathematical Practice 8: Look for and express regularity in repeated reasoning. Specific targeted skills in the PowerTeaching curriculum address the topic of repeated reasoning to find shortcuts, processes, and formulas. Expressions and equations Within the Expressions and Equations content area, students will prove expressions equivalent, prove or disprove solutions to equations and inequalities, and use the properties of addition and multiplication. Geometry Within the Geometry content area of PowerTeaching, students will apply their knowledge of expressions and equations to geometry and derive formulas for area, volume, and surface area.
