Math Content Unit Plan Group 1 Christina Furchi Jocylinn Andrews Denise Andretta Catherine Miller Geometric Shapes & Tessellations GRADE LEVEL: 7 CONTENT AREA: Math LENGTH OF UNIT: 10 Days DESCRIPTION OF STUDENTS: This math lesson is geared towards SED (Severely Emotionally Disturbed) students in grade 7. They come from low socio-economic families. They are standard diploma but perform academically 2 to 4 grade levels behind. There FCAT scores put them at a Level 1 or Level 2. These students struggle in all academic areas and require much scaffolding. ABSTRACT: In this unit, students will work with two-dimensional and three-dimensional shapes as well as the spatial concepts of turning, sliding, and flipping figures. The properties of polygons will be reviewed, also. Students will connect tessellations to their everyday life after learning the history of this math and art form. M.C. Escher will be introduced as an artist who has incorporated these two disciplines well. Children will then practice simple sketches and eventually develop a final project. These will be used for a class discussion on their mathematical properties, and finally, written about. OBECTIVES: 1. Students will identify geometric shapes in the real-world. 2. Students will become familiar with math in history, art, science, reading and writing. 3. Students will identify various angles: acute, obtuse, right, and straight. 4. Students will design various angles: acute, obtuse, right, and straight. 5. Students will identify various triangles: equilateral, right, obtuse, acute, scalene, and isosceles. 6. Students will design various triangles: equilateral, right, obtuse, acute, scalene, and isosceles. 7. Students will identify properties and characteristics of polygons: triangle, square, rectangle, quadrilateral, pentagon, hexagon, octagon, parallelogram, trapezoid and rhombus. 8. Students will be able to differentiate two-dimensional and three-dimensional polygons. 9. Students will be able to turn, slide, and flip polygons. 10. Students will summarize in writing what they have learned from tessellating. 11. Students will construct a tessellation using geometric shapes learned.

Day #2-3 – Angles: Review real-world geometric shapes. Identify and construct angles such as acute, obtuse, right, and straight. Day #3-4 – Triangles: Review all types of angles. Identify and construct triangles such as equilateral, right, obtuse, acute, scalene. Day #5-6 - MIDDLE – Polygons: Review real-world geometric shapes, angles, and triangles. Classify and construct shapes which are and are not polygons. Students will make a foldable to help differentiate polygons. Day #7 – Quadrilaterals: Review polygons. Identify and construct quadrilaterals such as parallelogram, trapezoid, and rhombus. Day #8 – Transformations & Reflections: Review all polygons and geometric shapes including angles. Duplicate geometric shapes by flipping and turning objects on graph paper. Beginning introduction of tessellations. Write the word “tessellation” on the blackboard. Tell students the word derives from the Latin language and represents the small square tiles used in Roman mosaics. Day #9 – Art & History: Introduce M.C. Escher as a brilliant Dutch artist who preferred to tessellate life forms rather than geometric shapes. Students will read the Biography of M.C. Escher and view his artwork. Day # 10 - END: Review M.C. Escher’s work and polygons and geometric shapes covered. Final Project – Completed tessellation and rubric. ASSESSMENT & EVALUATION: Tessellation Project (with Rubric) Polygon or NOT!!! Pre & Post Tests Verbal/Individual Shapes Naming Response Cards Tessellation or NOT!!! BEGINNING LESSON: Objective: Students will identify geometric shapes in the real-world. Essential question: Is the world constructed of geometric shapes? Warm-up: Students enter the class with the essential question on the board. Students are then instructed of the Geometry Walk Race. Procedure: The class will begin with a Geometry Walk (Interest Activity). Student will be split into 2 groups and given a pack of sticky notes (both teams will have a different color). Students will race to tag the most geometric shapes as they can locate throughout the classroom. A chart of geometric shapes will be posted to help in the search. Wrap-up: When time is up we will tally the findings. Students will summarize in their own words their findings. I will tell the students the shapes I have found if different from their own. Students will also take a pretest to check for content knowledge of Geometric Shapes. Students will be given homework. Homework: Students will need to make a list of things they find at home or in their environment that are constructed out of geometric shapes. MIDDLE LESSON: Warm-up: Students will play the Geometry Walk Race again for review. Students will be split in teams as before only this time they will be timed and have only 10 minutes. After this race is done we will look at a list of polygons. Procedure: Students will look at the lesson in their math books. We will work through this lesson and draw polygons as we go. Students will need to make a foldable which includes picture cards which contain the polygon and the numbers of sides that make up the shape as well as the name of each polygon. Wrap-up: The foldable will be review for accuracy. Student assessment is based on the foldable. Review of homework assignment for tonight. Homework: Students will complete lesson sheets out of the student supplement book for the polygon lesson. END LESSON: Objective: Students will summarize in writing what they have learned from tessellating. Students will construct a tessellation using geometric shapes learned. Warm-up: Students will review M.C. Escher’s work and polygons and geometric shapes covered. Students will come to the board and construct their favorite polygon/geometric shapes. Procedure: Students will read about tessellations and discus what constitutes a tessellation design. Key points of the reading are: Tessellation: a covering of a plane, without any gaps or overlays, by a pattern of one or more congruent shapes. Tessellations are designs made up by shapes that completely cover a surface without any gaps or overlays. There is repetition in the pattern. Students will create and construct a tessellation of their own. Scoring will be based on the rubric criteria. Wrap-up: Students will examine another student’s tessellation and examine if all criteria was covered and whether or not a tessellation was successfully created.
