Geometry By: Brittany Kelley

Introduction 10 Day Unit Teaches basic geometry terms and concepts to 8 th grade students Integrates technology in a fun way

Analyze Learners Taught in 8 th grade classroom Ages 13 to 14 Should be briefly introduced Review and advance knowledge Classroom includes wide range of learners

State Objectives M. O. 8. 3. 1 Justify the relationships among corresponding, alternate interior, alternate exterior and vertical angles when parallel lines are cut by a transversal using models, pencil/paper, and technology. M. O. 8. 3. 2 Classify polyhedrons according to the number and shape of faces; use inductive reasoning to determine the relationship between vertices, faces and edges (edges + 2 = faces + vertices). M. O. 8. 3. 3 Identify, apply, and construct perpendicular and angle bisectors with and without technology given a real-world situation. M. O. 8. 3. 4 Create geometric patterns including tiling, art design, tessellations and scaling using transformations (rotations, reflections, translations) and predict results of combining, subdividing, and changing shapes of plane figures and solids.

State Objectives (cont. ) M. O. 8. 3. 5 Create scale models of similar figures using ratio, proportion with pencil/paper and technology and determine scale factor M. O. 8. 3. 6 Make and test a conjecture concerning regular polygons, the cross section of a solid such as a cylinder, cone, and pyramid, the intersection of two or more geometric figures in the plane (e. g. , intersection of a circle and a line), and justify the results. 21 C. O. 5 -8. 2. TT 3 Student uses multiple technology tools for gathering information in order to solve problems, make informed decisions, and present and justify the solutions.

Utilize Media and Materials Day 1 • Review basic concepts & terms • Power. Point Presentation • Handout with Power. Point Day 2 • Lines & Angles • Geometer’s Sketchpad with Smartboard • Students construct object on board

Utilize Media and Materials (cont. ) Day 3 • Review angles with bulletin board • Worksheet on bulletin • Introduce 3 -D objects with classroom object • List objects for homework Day 4 • Student with most examples gets a prize • Introduce three day long project § Building project with group § Need to know how geometric factors are functional in project

Utilize Media and Materials (cont. ) Day 5 • Entire class time to work on building projects • Ask question while they work as a group Day 6 • Each group gives a 35 min. presentation about their building • Graded on Presentation and overall project

Utilize Media and Materials (cont. ) Day 7 • Classroom discussion on polyhedrons • Create own polyhedrons and turn in for a grade • Last 20 minutes doing internet activity Day 8 • Worksheet reviewing previous day • Discuss symmetry and transformations • Each students comes to board to draw line of symmetry

Utilize Media and Materials (cont. ) Day 9 • Watch movie – “The Standard Deviants – Geometry (pt. 1 & 2)” • Worksheet on video to keep students on task Day 10 • Instead of formal exam students participate in a variety of activities, including Geometry Simon Says.

Require Learner Participation Individual and group activities Wide range of learning styles Most work completed on their own Required handouts to be turned in for grades Hold attention with various forms of technology ranging from the interactive Smartboard, to online activities

Evaluate and Revise M. O. 8. 3. 1 – Presentation on building project M. O. 8. 3. 2 – Create own polyhedrons M. O. 8. 3. 3 – Construct building and give presentation M. O. 8. 3. 4 – Students come to board to demonstrate symmetry and create tessellations M. O. 8. 3. 5 – Unofficially evaluated while working on building project M. O. 8. 3. 6 – Evaluated by giving examples of 3 -D objects for homework 21 C. O. 5 -8. 2. TT 3 – Informally assess student’s basic understanding of symmetry by using the Smartboard on day 8
