3-D Objects and 2-D Shapes
This tool lets you to transform a plus sign in eight different ways: rotate it ¼, ½, ¾, or a full turn, or flip it vertically, horizontally, or diagonally.
Take a look at these nets (two-dimensional figure that can be folded into a three-dimensional object). Which ones will form a cube?
You can play with various geometric solids and their properties by manipulating the colors and shape to explore the number of faces, edges, and vertices.
Isometric Drawing Tool
Create dynamic drawings on isometric dot paper. Draw shapes using edges, faces, or cubes. Shift, rotate, color, and view in 2‑D or 3‑D. Start by clicking on the cube along the left side; then, place cubes on the grid where you would like them.
LearnAlberta: Exploring Angles and Parallel Lines
Explore the angle relationships created by a transversal intersecting with parallel lines. The angle terms adjacent, opposite, complementary, corresponding and alternate are defined and explained.
Math Playground: Alien Angles
This activity will let you see how well you estimate angles. You will be given an angle to aim for. Drag the blue ball along the line to set your angle.
Use the animation on this site to explore the properties of four prisms. Follow the instructions to change the direction and speed of the prism's rotation and to highlight the faces, vertices, and edges for each prism.
Shape & Space (Grade 7)
Resources and lesson plans from Blackgold school district that are focused on calculating spaces. If you click the links, there is a sign-in prompt -- but you can bypass the sign-in by clicking the image instead and will be able to access all the Google slides associated with that image
Shape and Space (Grade 8)
Resources and lesson plans from Blackgold school district that are focused on polygons. If you click the links, there is a sign-in prompt -- but you can bypass the sign-in by clicking the image instead and will be able to access all the Google slides associated with that image
This activity lets students experiment with different tools: Patch Tool, Cutting Corners, and Mirror Tool. Use it to create many kinds of shapes.
TED: The mathematics of sidewalk illusions
Learn about the technique involved with sidewalk illusions where artists represent 3D views on 2D surfaces. This video describes perspective, with specific reference to 3D street art.
Students can explore the tessellations they can make out of regular polygons.
