MGSE7.G.3 Describe the two-dimensional figures (cross sections) that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres.

Unit 4 : Students will learn to draw geometric figures using rulers and protractors with emphasis on triangles. Students will explore two-dimensional cross sections of cylinders, cones, pyramids, and prisms.

Draw these geometric shapes: cones cylinders pyramids spheres right rectangular prisms right rectangular pyramids right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres

Draw these geometric shapes: cones cylinders pyramids spheres right rectangular pyramids right rectangular prisms right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres

Learning goal #1: Students will learn how to identify and draw three-dimensional figures; right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres.

Review Geometric Shapes

Students will work in small groups and practice circling a given geometric shape.

Instructional Activities: Teacher will review the basic 2D and 3D geometric shapes. Students will practice identifying, labeling, and drawing the main geometric shapes for standard G3. right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres c) Students will create a graphic organizer that will focus on the main geometric shapes and the three main cross-section cuts (horizontal, vertical, and diagonal).

Instructional Activities: Students will watch a video on cross sections of geometric shapes. Students will also make a matching cut-out shape and vocabulary word game. Students will take a 10 question Assessment. Math Shorts Episode 8 - Slicing Three Dimensional Figures
