New ReviewHow well do your classes understand scale? You'll certainly know after they answer the set of eight questions from an informative and helpful presentation. Questions include items from coordinate geometry, similar triangles, and scale...

New ReviewThe view depends upon location. A short video introduces the idea of views and elevations of 3-D figures. Using figures composed of cubes, the presenter creates their front, side, and plan views. The last figure requires the viewer to...

Calculate one hypotenuse then repeat. The resource provides a variety of ways for finding the length of the diagonal in a prism. Using the Pythagorean Theorem, pupils find a variety of distances in 3-D figures. The distances range from...

Do the math before you do something crazy—like filling a pool full of Coca-Cola. A video shows a pool owner filling a large backyard pool with bottles of Coke. Scholars use the dimensions of the pool to determine the number of bottles...

You've netted a great resource! Young mathematicians learn about the nets of three-dimensional solids by watching a brief video. The resource includes some test-taking tips on the topic for those studying for the GCSE.

Quick, name that shape! Scholars learn the names and common properties of three-dimensional solids. They watch a short video that shows an example of each shape and identifies the two-dimensional faces that make up its surfaces.

Who knew there were so many parts to a geometric solid?! Well, you probably did, and your pupils will, too, after watching a video lesson on three-dimensional figures. Instruction includes a description of the parts of solids, naming...

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Investigate the volume of irregular figures in an inquiry-based exercise. Presented with an irregularly shaped box filled with water, learners must predict the level of water when it is tipped on its side. The class can divide the figure...

Combine the formulas to arrive at one volume. Using the formulas for different solids, the video introduces finding the volume of composite solids. The portion of an extensive playlist on geometry works a couple of problems, one with an...

Slice up solids. A portion of a geometry playlist introduces two conventional ways to visualize 3-D figures in 2-D. The resource defines cross-sections and nets and provides examples of both.

Blow up a solid by a scale factor. A section of a larger playlist on basic geometry introduces the ratios of the surface areas and volumes of similar solids. Using the ratios, the video works several examples involving similar figures.

Imagine a poly-what? With the aid of pictures, the segment of an extensive geometry playlist introduces specific polyhedrons and their parts. The presentation uses Euler's Theorem to explain the relationship between the number of faces,...

Drawing in three dimensions gives scholars some perspective. The first lesson plan in a six-part unit on isometric drawings encourages pupils to use paper and pencil to draw in three dimensions. They then explore an online interactive...

How is a molecule's shape determined? Explore bond angles, lone pairs, and VSEPR theory through a logic-based activity. Chemists pull together information about the major molecular shapes, then use it to solve puzzles.

Everyone's heard of the Lone Ranger ... but what about the Lone Pair? Part two in a mini-series from a JFR Science playlist explains the geometry of molecules with unbonded pairs of electrons. The narrator explains each family of...

Bring molecules to life! Show science scholars how atoms around a central atom arrange themselves using a video from JFR Science, the first in a two-part series on VSEPR theory. The narrator explains the basics of the theory, then...

Ready to take molecules out of the two dimensional world and into 3-D? Chemistry scholars explore molecular geometry through a well-written video from the JFR Science series. Topics include the effects of bonding and non-bonding...

Geometry welcomes you. A short video in the Socratica Geometry playlist provides an overview of geometry. It explains some concepts and gives a brief history of geometry.
