Describe 2-Dimensional Cross Sections of Right Rectangular Prisms
5 mins 7th - 10th CCSS: Designed
Help your learners visualize the resulting shape when a right rectangular prism is sliced with a two-dimensional plane in this first video in a series of two. Start by going over the key vocabulary shown at the beginning of the core...
Representing Three-Dimensional Figures Using Nets
6th CCSS: Designed
Unfold the faces of a three-dimensional figure. Scholars define a net and determine whether drawings are nets or not. They compare nets with their associated 3-D figures and identify the various faces to finish the 16th segment in a...
Use Nets to Represent Three-Dimensional Figures and Find Surface Area (6.G.A.4)
6th - 8th CCSS: Adaptable
The nine resources in this collection model how to explore surface area with different shapes and how to use nets to help visualize these shapes. The last two videos in the series are application-based and test the skills developed by the prior videos.
Using Linear Equations to Define Geometric Solids
9th - 12th CCSS: Designed
Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive Common Core lesson plan starts with writing and graphing linear equations to define a bounded...
How Do You Identify a Three-Dimensional Figure from a Net?
8 mins 6th - 8th
Learn how to use two-dimensional nets to identify their corresponding three-dimensional figure. The instructor uses diagrams to illustrate the two-dimensional nets and talks about the characteristics of each one to identify its...
Surface Area of Three-Dimensional Figures
8th - 11th CCSS: Adaptable
Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...
