HAPG Survey

The purpose of this cover page is to provide support for understanding the Horizontal Alignment Planning Guide fields in order to effectively plan instruction. The HISD philosophy for Horizontal Alignment Planning Guides (HAPG) is to serve as the district guide that outlines the nonnegotiable curriculum objectives, supports meaningful instruction based on promising practices, and serves as the springboard for effective instructional planning. Therefore, HAPGs serve as a framework to support the development of units of instruction. Learning Focus: This field provides a unit title with a brief description of the main idea for a unit of study. Each Learning Focus is numbered indicating the grading cycle followed by the unit of instruction within the learning cycle. Ex. Learning Focus 1.1. Key Concepts: This field provides ideas that assist students with transfer of knowledge from the factual level to the conceptual level and may be used by teachers to write essential understandings. Concepts meet the following criteria: common attributes, timeless, universal, abstract, and broad. In English Language Arts, information under this field may also include words that represent Readers or Writers Craft. One or more concepts will be underlined in the Learning focus to assist teachers in planning a concept-based unit of study. Key Skills: This field identifies processes that represent the ability of the student to use knowledge effectively or to execute a performance.

Instructional Strategies

Resources

Use multiple-choice questions as formative assessments by having students explain not only the correct answers but also the incorrect answers. Using the graphic organizer provided in the formative assessment attachment, students first answer the question as indicated as if it is an open-ended question. Then students will look at all the possible answer choices. For the correct answer, the student adds justifications for the answer given. For the distracters, students must give reasons for why the answer is incorrect: word clues, process mistakes, or concept mistakes. Students may prove the mistake mathematically or in a written statement.

Formative Assessment 2.1 – Assessment for Multiple Choice Questions contains a Multiple-Choice Item Analysis graphic organizer as well as rubrics for evaluation purposes: • Teacher rubric • 6 – 8 Student rubric

If the formative assessment is given after a multiple choice test has been administered, students may use this process to check and correct their work. Even if the student has the question correct in the original testing, he/she must also prove why the incorrect answers are not possible. Region IV Rubrics are provided for evaluation purposes (Formative Assessment 2.1 – Assessment for Multiple Choice Questions – see Resources column).

Nonlinguistic Representations Geoboard or Grid Paper Activity To begin, illustrate a square placed at right angles with the dots or pins. Students have no problem with finding the area or side length of a construction that is “square” with the grid. However, when the square is “tilted” as shown below, the counting strategy students often use is ineffective (Activities: Teaching Math with Manipulatives, Lab activity in the textbook – see Resources column).

Primary Textbook Resource: Glencoe, Texas Mathematics, Course 3 • TWE/SE, 3-1, 3-2 & 3-4, pp. 144 – 151, 162 – 171; • Lab Activity, p. 161; • Ch. 3 resource masters, pp. 9 – 22, 27 – 45; • Teaching Math with Manipulatives, pp. 43 – 44, 46 – 47; • Mathscape: Roads and Ramps, pp. 236 – 239.

Connections to Future Objectives/ Assessments Students will use the Pythagorean Theorem in algebraic and geometric contexts in this grade and beyond. Essential Understandings/Guiding Questions The Pythagorean Theorem can be used to solve problems involving right triangle relationships. 1. How can the area of a “tilted” square be determined? 2. How is the measure of the hypotenuse of a right triangle related to the measures of the other two sides (legs)? 3. How can models be used to demonstrate the Pythagorean Theorem? Background Knowledge for Teacher Critical Content: • Explore Pythagorean Theorem using models.

MATH.7.15A/ MATH.8.16A Make conjectures from patterns or sets of examples and nonexamples.

Instructional Strategies

The Pythagorean Theorem should be demonstrated using models, both concrete and pictorial. In hands-on activities, be sure that students discover or experience: • that the hypotenuse is always the longest side and its relationship to the placement of the right angle; • that the Pythagorean Theorem is only true of right triangles; • the use of letters other than a, b, and c in examples; • identification of models of examples and nonexamples of the Pythagorean Theorem.

Objective Code Key: Elementary – Content Area.GradeLevel.Objective Secondary – Course.Objective

T - TAKS (Obj) = TAKS objective tested *(x) - Grade level Assessed on TAKS

Cooperative Learning Students work in pairs or small groups to discover a “system” for finding the area of such a tilted square.

Nonlinguistic Representations Think-Aloud Students collect information about the area of squares on the sides of right triangles drawn on dot paper or illustrated on a geoboard. Use a Think-Aloud strategy to relate the information they discovered previously to find the area of the “tilted” square on the hypotenuse of a right triangle as well as those on the legs of the triangle (Activities: Modeling the Pythagorean Theorem, “Pythagorean Theorem Investigation” (LTF activity) – see Resources column).

Clarifying Activity: Modeling the Pythagorean Theorem is a manipulativesbased activity that includes student activity masters and extensive teacher notes.

Print Resource: “Pythagorean Theorem Investigation” is an application problem found in the Laying the Foundation, Resource and Strategy Guide, Advanced Placement Strategies, Inc, 2004, pp. 220 – 224.

Time Allocation

Assessment Connections

Instructional Considerations There are two common solutions for finding the area of a tilted square: • Enclosing the square in a large square and subtracting the “outside” triangular area. • Subdividing the square into small regions and combining their area.

After students have found the area of the squares, they should see how area relates to the side length and how that is connected to the concepts of square root and irrational numbers. For example, the connection between a square 2 of area 5, the formula A = 5 , and the side length of

5 should be made.

A statement of the relationship between the lengths of the sides of a right triangle should be the ultimate goal of an investigation of the model of the squares on those sides. This observation leads to the verbalization of the Pythagorean Theorem.

Instructional Strategies Summarizing and Note Taking Graphic Organizers As students gather data from various right triangles and the squares on their sides, they should be recording their notes and observations using some form of an organizing grid such as a t-chart or table (Activities: Pythagorean Squares and Activity 8.7C in the Mathematics Toolkit – see Resources column).

Nonlinguistic Representations A non-linguistic representation or visual explanation linking the discoveries from the previous activity will help some students understand the essence of the Pythagorean Theorem. 1(A)

Instructional Considerations Prerequisites/Background Knowledge for Students This is the first formal work with the Pythagorean Theorem. Previously, students identified right triangles and their properties. Connections to Future Objectives/ Assessments In Geometry, students will derive, extend, and use the Pythagorean Theorem. Essential Understandings/Guiding Questions The Pythagorean Theorem can be used to solve problems involving right triangle relationships. 1. How can the Pythagorean Theorem be used to find a missing side of a right triangle? 2. How is the Pythagorean Theorem used to determine if a triangle is a right triangle? 3. What kinds of real-world problems can be solved using the Pythagorean Theorem? Background Knowledge for Teacher Critical Content: • Apply the Pythagorean Theorem

After discovering the Pythagorean Theorem through exploration, students should apply it in numerous application situations (Power Objective 8.9A). Vocabulary Academic Models

Content-Specific Right triangle relationships Legs Hypotenuse Pythagorean Theorem Pythagorean Triples

TAKS Tips Illustrate the power of the Pythagorean Theorem using contextual problems that apply the theorem in various situations. For example, a common application used in testing situations is finding distances on maps or in illustrated situations. In working with the Pythagorean Theorem, students should: • use a calculator (Obj. 8.1E) • estimate solutions; • solve application problems that: o include fields such as art and architecture; o involve finding a leg when given the length of a leg and the hypotenuse of the triangle; o include multi-step solutions; and • evaluate solutions for reasonableness.

Instructional Considerations Prerequisites/Background Knowledge for Students Sixth-grade Pre-AP students used words and symbols to describe the terms in an arithmetic sequence (with a constant rate of change) and their positions in a sequence; and represented those sequences using a variety of strategies (including concrete models, tables, algebraic rules, and graphs).

Instructional Strategies Nonlinguistic Representations

Engage students by using manipulatives such as geoboards, color tiles, pattern blocks, or graph paper to create concrete and pictorial representations of visual patterns that are then “translated” into the other representations (Activities: Borders, Cutting a Pizza, Graphs of a Sequence – see Resources column). 4(F)

Connections to Future Objectives/ Assessments In this course and in Algebra I, students write and solve equations given other representations of data.

Essential Understandings/Guiding Questions Patterns and sequences help to discover, analyze, describe, extend, and formulate understandings of mathematical relationships and real-world phenomena. 1. How do patterns and sequences occur in the real world? 2. How can we use patterns and sequences to solve real-world problems? Patterns and algebraic relationships can be represented with multiple representations (e.g. tables, graphs, symbols, and verbal descriptions). 1. How can patterns, represented either concretely or pictorially, be described with words and symbols? with tables and graphs? 2. Why are patterns and relationships represented in multiple ways? Expressions and equations are algebraic representations of patterns or sequences. 1. How can a pattern in a table or chart be recognized? 2. How can an expression or equation represent a relationship from the everyday world?

Performance Expectations By the end of this learning focus, students will generate and use multiple representations of the same data, solve equations that model real – world problems involving patterns and algebraic representations and predict, find, and justify solutions to application problems involving data displayed in various ways.

Summarizing and Note-Taking Two-Column Notes Function machines are a logical extension of patterning activities. Interactive virtual function machines are very helpful visual representations that allow students to make connections between “input” and “output” and relate these to other vocabulary such as “independent” and “dependent.” The actions that function machines simulate also help students formalize the use of function rules. Use a two-column note-taking strategy to create t-charts for the input and output values of the function machines with a summary box used for recording the formula rule in both verbal and symbolic forms.(Virtual Activities: Function Machine, Introduction to Functions, Introduction to Linear Functions, Understanding Math 2008 – see Resources column).

Technology Resources: • Function Machine at National Library of Virtual Manipulatives • Interactivate, The Shodor Education Foundation, Inc.) • Introduction to Functions • Introduction to Linear Functions • Patterns and sequences are found in Topics 1 and 3 of Understanding Algebra in Understanding Math 2008, Neufeld Learning Systems

Background Knowledge for Teacher Critical Content: • Write a rule for an informal pattern represented concretely or pictorially; and • Write a rule (expression) for function relationships presented in tables or as verbal descriptions.

Objectives 8.4A and 8.5B involve informal patterns and the multiple representations of the functions behind them. Power Objectives 7.14A and 8.15A references the use of these multiple representations at the application level. Begin by introducing familiar arithmetic sequences of numbers (constant rate of change) in t-charts and relating them back to concepts previously covered on proportionality (e.g. independent and dependent relationships, proportional vs. non-proportional relationships, ordered pairs, linear relationships).

Cooperative Learning In small groups, students elaborate on and apply the knowledge and skills acquired by completing rigorous applications and tasks within real-world contextual problems (Laying the Foundation Activity: “The Best Payment Plan” – see Resources column).

Print Resource: “The Best Payment Plan – Using Sequences” is an application problem found in the Laying the Foundation, Resource and Strategy Guide, pp. 182 – 188.

Move to formalizing relationships observed in the t-charts using finite differences and introduce the function rule for the relationship observed. Vocabulary Academic Models Patterns Input Output Function

Content-Specific Sequences Rate of change Finite Differences Function machines Independent variables Dependent variables

TAKS Tips At the seventh grade level, students are expected to be able to: • write an expression to find the nth term where n represents the position of the term in the arithmetic sequence; and • identify the expression when given terms in and arithmetic sequence, and vice versa. What is it we want all students to learn?

Instructional Strategies

Prerequisites/Background Knowledge for Students Sixth-grade grade Pre-AP students wrote problem situations when given a simple equation and wrote equations when given a problem situation.

Cues, Questions, and Advance Organizers KWL To help students recall the order of operations, use an acronym such as GEMDAS (Grouping Symbol – Exponent – Multiplication – Division – Addition – Subtraction). This cue is different from that which most students are familiar in that the G stands for “grouping symbols.” Use a KWL graphic organizer to help students connect to their prior knowledge.

Connections to Future Objectives/ Assessments In this course, students write and solve equations given other representations of data. Essential Understandings/Guiding Questions Equations express relationships between two algebraic representations or expressions. 1. How are expressions simplified? 2. How is an equation different from an expression? 3. What does the “=” in an equation mean? Background Knowledge for Teacher Critical Content: • Order of operations; • Evaluate expressions; and • Write equations.

Objectives 8.4A and 8.5B involve informal patterns and the multiple representations of the functions behind them. Power Objective 8.15A references the use of these multiple representations at the application level. If students have had little or no previous exposure to algebraic models (e.g. Algebra Tiles), spend time discussing what each type of tile represents when introducing the models. Provide time for the students to practice using the models, both determining what a given tile arrangement represents and using the tiles to model a given expression.

As an important step in transitioning to the abstract level, students should be “recording” their steps first in pictorial form as they use the concrete manipulatives and then move to the symbolic recording process (Power Objectives 7.14A and 8.15A). 1(E) Vocabulary Academic Evaluate Patterns Models

Nonlinguistic Representations Write an algebraic expression such as 2 (4 + 1) – 6 – 3 + 5 on the board and ask the students to create index cards with each symbol and number. They then rearrange the cards to create new expressions that: • changes the numbers in order to have a greater or lesser value; • changes the grouping symbols in order to have a greater or lesser value; • change the operations in order to have a greater or lesser value; • change a combination of the grouping and operations to have a greater or lesser value.

Have students also (using their cards) model the largest and smallest value (Activity 7.2E in the Mathematics Toolkit – see Resources column). Cooperative Learning Group students in pairs or small groups to explore algebraic models such as Algebra Tiles or cups and counters to model representing expressions and equations concretely (Textbook, Teaching Mathematics with Manipulatives, pp. 36 – 37). Homework and Practice Use interactive virtual videos/activities to assist students in their conceptual understanding (Activities: BrainPOP movie “Order of Operations” and Understanding Math 2008 – see Resources column).

Essential Understandings/Guiding Questions Inverse operations and the property of equality are used to solve algebraic equations. 1. How are inverse operations used to solve equations? 2. How are mathematical properties used to solve equations? Graphs of equations are visual representations of the algebraic relationships involved in real-world problems. 1. How does a graph of an equation relate to the equation? 2. What are the advantages of using a graph to represent an algebraic equation? Background Knowledge for Teacher Critical Content: • Solve addition and subtraction equations; • Solve multiplication and division equations; • Solve equations with rational numbers; • Simplify algebraic expressions; • Solve two-step equations; • Write two-step equations; and • Solve equations with variables on each side.

Instructional Strategies Nonlinguistic Representation Students begin their explorations with algebraic reasoning on the concrete and pictorial levels and move to the abstract only after they have an understanding of the processes involved in solving equations (Activities: Texas Mathematics, Course 2: Algebra Lab: Solving Equations using Models, pp. 182 – 183 or Activity 7.5A in the Mathematics Toolkit). 2(E)

Cues, Questions, and Advance Organizers Graphic Organizers When students move to the abstract level in application problems, help students relate the step-by-step process back to the concrete or pictorial level. Students explain their reasoning by creating a chart with columns entitled “verbal description,” “equation,” and “picture.” Give students information in one column and ask them to generate the corresponding information in the other two columns.

Cooperative Learning Students work with a partner in a concentration-style activity to explain their understanding of the multiple representations of algebraic situations (tabular, graphic, and symbolic) (Activity: Algebraic Concentration – see Resources column). 3(E), 4(I) Cooperative Learning In small groups, students apply the knowledge and skills acquired by completing rigorous applications and tasks within realworld contextual problems (Laying the Foundation Activities – see Resources column).
