Tuesda y MGSE7.G.3 Describe the twodimensional figures (cross sections) that result from slicing threedimensional 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 twodimensional cross sections of cylinders, cones, pyramids, and prisms. Draw these geometric shapes: cones

cylinders right rectangular pyramids pyramids

spheres right rectangular prisms right rectangular prisms, right rectangular pyramids, cones, cylinders, and spheres

Draw these geometric shapes: cones cylinders

right rectangular pyramids pyramids spheres

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 geometri c shape.

Instructional Activities: a) Teacher will review the basic 2D and 3D geometric shapes. b) 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: d) Students will watch a video on cross sections of geometric shapes. Math Shorts

Episode 8 - Slicing Three Dimensional Figures e) Students will also make a matching cut-out shape and vocabulary word game. f) Students will take a 10 question Assessment. Cross Sections
