WOODLAND HILLS HIGH SCHOOL LESSON PLAN SAS and Understanding By Design Template Name Broadwater Date Nov 21-Dec 13 Edline was updated this week: Length of Lesson 14 days Content Area Geometry My Class website was updated this week: STAGE I – DESIRED RESULTS LESSON TOPIC: Circles BIG IDEAS: (Content standards, assessment anchors, eligible content) objectives, and skill focus) 2.2.11 B Use estimation to solve problems for which an exact answer is not needed. 2.2.11 D Describe and explain the amount of error that may exist in a computation using estimates. 2.3.11.A Select and use appropriate units and tools to measure to the degree of accuracy required in particular measurement situations. 2.3.11.B Measure and compare angles in degrees and radians. 2.3.8.E Describe how a change in linear dimension of an object affects its perimeter, area and volume. 2.9.11.F Use the properties of angles, arcs, chords, tangents and secants to solve problems involving circles UNDERSTANDING GOALS (CONCEPTS): Students will understand: Find angle measures of central, inscribed, interior, and exterior angles; find arc measure and length of circles. Special properties of circles are explored including the fact that a circle is a unique geometric shape in which the angles, arcs, and segments intersecting that circle have special relationships.. ESSENTIAL QUESTIONS: Can you…? 1.Determine parts of a circle and find circumference 2.Determine the measure of central angles and their arcs, identifying and name major and minor arcs 3.Use the relationships between arcs and chords to solve problems 4.Draw, label, and find measures of inscribed, interior, exterior, and circumscribed angles 5.Identify a tangent and use the properties to solve a problem 6.Determine how to solve real life problems using circles and segments VOCABULARY: Chord, circumference, arc, tangent, secant, center, central angle, circumscribed, diameter, inscribed, intercepted, major and minor arcs, point of tangency STUDENT OBJECTIVES (COMPETENCIES/OUTCOMES): Students will be able to: 1.Identify and use parts of circles. Solve problems involving the circumference of a circle. 2.Recognize major arcs, minor arcs, semicircles, and central angles and their measures. Find arc length. 3.Recognize and use relationships between arcs and chords, and between chords and themselves. 4.Find measures of inscribed angles. Find measures of angles of inscribed polygons. 5.Use properties of tangents, solve problems involving circumscribed polygons 6.Find measures of angles formed by lines intersecting on or inside, or outside a circle. 7.Find measures of segments that were in the interior or exterior of a circle. STAGE II – ASSESSMENT EVIDENCE PERFORMANCE TASK: Students will actively participate in class examples, discussion, classwork, group discussion, and activities FORMATIVE ASSESSMENTS: #1. Exit Tickets #2. Pre-Assessment #3. Graphic Organizers Others: Summarizing Main Idea, Open-Ended Questions, Think-Pair-Share STAGE III: LEARNING PLAN INSTRUCTIONAL PROCEDURES: MATERIALS AND RESOURCES: Active Engagements used: #1. Note-Taking #2. Compare Contrast Others: Graphic Organziers, Summarizing, Cooperative Education, Partnering, ThinkPair-Share Unit 8 Quadrialterals (Glencoe Geometry text) Describe usage: See below for Compare/Contrast, Graphic Organizers, Cooperative Education, Partnering, NoteTaking, Think-Pair-Share. Check for understanding and summarizing using warm up, homework, formative assessment questioning or exit tickets to determine whether to continue lesson or do interventions as needed. (model, spiral scaffolding, instruct/ reteach as needed) Scaffolding used: #1. Guided Notes #2 . Build on Prior Knowledge Others: Graphic Organizers, Build Vocabulary, KWL Describe usage: Warm up to Warm ups (daily) Homework (daily) “Grab & Go” worksheets/ activities Unit Test Additional materials as needed (rulers, compass, grid paper, etc) Teach made packets to enhance the material in the unit. CONTENT AREA READING: Guided Notes INTERVENTIONS: ASSIGNMENTS: Struggling students will be referred to RTII and Math Lab Small group/flexible grouping will occur. Various computer programs. *10.1 - p. 526-527 #32-54 even *10.2 Day 1 - p. 533-535 #1431, 32-42 even, 58 *10.2 Day 2 - Practice WS *10.3 Day 1 - p. 540 #11-20 and 23-35 odd *10.3 Day 2 - Practice WS *10.4 Day 1 - p. 549 - 550 #810, 13-16, 22, 25 *10.4 Day 2 - Practice WS *10.5 Day 1 - p. 556-557 #818, 23 *10.5 Day 2 - Practice WS *10.6 Day 1 - p. 564 -565 #1232 even *10.6 Day 2 - Practice WS *Chapter 10 Review include spiraling review of prior knowledge to include upcoming lesson. All notes are guided notes to build vocabulary, interspersed with group activities. Graphic organizers utilized when appropriate to compare/contrast vocabulary. KWL used with chapter vocabulary at beginning and end of each chapter. Other techniques used: MINI LESSON: Based on daily assessments (formative and summative), additional modeling, instruction, homework, review, interventions, group work, computer or teacher guided practice will be done.
