Geometric Figures Created by: Carol Sweat School Name: Kelly Elementary Subject: Math Grade Level: 4th State Standards and Indicators: (4) 3.1.A2 Identify, name, describe and solve real world problems using the properties of geometric figures and their component parts (sides, angles). Activity Instructions: Page 2 & 3 - Provide each student with a paper copy of a cube. On each face of the cube the students will create the various quadrilaterals. I used linguine or fettuccine noodles (they are easy to cut with a scissor and the flat side glues easier). Glue the cube together after the quadrilaterals have been created. Use the Smartboard lesson to model for the students. Have the students discover what component parts (sides, angles) are needed to create each quadrilateral. Page 4 & 5 - Provide each student with a paper copy of a pyramid. Repeat the steps you followed with the quadrilaterals to create triangles named by their sides. Page 6 & 7 - Provide each student with a paper copy of a pyramid. Repeat the steps you followed with the quadrilaterals to create triangles named by their angles. Page 8 & 9 - Compare the properties of geometric figures by completing the polygon tree. Each polygon can be cloned and placed throughout the polygon tree. Page 10 & 11 - Have students practice recognition of polygons as part of a composite figure. These are good to prepare for the state assessment.
