|Math Lesson: 2- and 3-Dimensional Shapes |Grade Level: 6 |

|Lesson Summary: Students classify two-dimensional and three-dimensional shapes. Advanced learners make patterns from regular polygons that form figures, and |

|struggling learners identify polygons by their names. |

|Lesson Objectives: |

| |

|The students will know… |

|that there are many different two-dimensional and three-dimensional shapes, each with different properties. |

| |

|The students will be able to… |

|recognize two-dimensional shapes as polygons. |

|define and classify polygons. |

|analyze characteristics and properties of a three-dimensional shape. |

|Learning Styles Targeted: |

| |

| |

|Visual |

| |

|Auditory |

| |

|Kinesthetic/Tactile |

| |

|Pre-Assessment: |

|Before students arrive, check your classroom to be sure that there are a number of two-dimensional and three-dimensional objects in the room. If necessary, add |

|items or pictures of two-dimensional and three-dimensional shapes. |

| |

|Give students post-it notes that read either two-dimensional or three-dimensional. Direct students to walk around the room and place their post-it notes on items |

|that they identify as two-dimensional or three-dimensional. Tell students that items shown on posters or photographs in the room can also be tagged. |

| |

|Note students who do not know the difference between a two-dimensional and three-dimensional object. |

|Whole-Class Instruction |

|Materials Needed: PowerPoint presentation*, a computer connected to a projector, paper, ruler, and nets |

|Procedure: |

|Presentation: |

|Walk students through PowerPoint Slides 2 through 7 explaining polygons, how to classify them, polyhedrons, and prisms. |

| |

|Guided Practice: |

|Describe a figure and have students draw it. Divide students into pairs and have them take turns describing a figure’s characteristics while the other student |

|draws the figure as described. Use pentagons, hexagons, triangular prisms, etc. |

| |

|Independent Practice: |

|Provide students with the names of the figures on slides 8 and 9 and have students list their properties. |

| |

|Slide 8 answers: |

|1. An octagon is an eight-sided polygon. |

|2. An equilateral triangle is a triangle with all three sides congruent. |

|3. A square pyramid is a polyhedron with a square base and equilateral triangles as faces. |

| |

|Slide 9 answers: |

|4. A hexagonal prism is a prism with hexagonal bases. |

|5. A convex polygon is a polygon that has no diagonal with points outside the polygon. |

|6. A pentagon is a five-sided polygon. |

| |

| |

|Closing Activity: |

|Show students a design patterns on slides 10 and 11. Have them find specific shapes and list the properties of each type. |

|Advanced Learner |

|Materials Needed: grid paper, ruler, and colored pencils |

|Procedure: |

|Have students make a two-dimensional design on grid paper that consists of regular polygons. Tell students that you want them to color code the polygons and make a|

|key that explains the color-coding. After students have finished working, allow them to share their designs with the rest of the group. |

|Struggling Learner |

|Materials Needed: paper and ruler |

|Review all of the polygons and their properties. |

| |

|Have students draw polygons based on descriptions that you provide. |

| |

|Discuss the polygons that they drew to make sure that they are correct. If not, provide correct sketch. |

| |

|Have students work in pairs where one student draws a figure that the other describes. |
