Using 3-D Models for Code Validation with FoilSim

Nothing like sitting on the porch enjoying a big slice of watermelon, unless it's square and then how do we cut it? This lesson plan starts with the cube and the shape possibilities when we make cuts in different locations. The activity...

Slice and dice like a master mathematician. Scholars determine and draw three possible cross-sections of a cube. Given a solid shape removed from a three-dimensional figure, they describe two viable original figures.

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Turn 2-D into 3-D using a simple rotation. The resource contains two questions concerning the rotation of a rectangle about the x-axis and the y-axis. Pupils identify the resulting solid and provide information about the dimensions.

Apply the Pythagorean Theorem in three-dimensional shapes. Young mathematicians watch a video that takes them through several examples of using the Pythagorean Theorem to solve problems involving lengths in three-dimensional figures. A...

Bring it all to three dimensions. The short video points out that the discussion in the previous presentations in two dimensions also holds true for three dimensions. The sixth video in the series of 15 specifically makes the connections...

It's about to get 3-D! The video shows your class how to expand the midpoint formula to find the midpoint of a three-dimensional segment. The example shown calculates the midpoint using the x-, y-, and z-coordinates.

Building on prior knowledge about defining variables, the second video in this series on coding explains how to perform simple operations with data in JavaScript. Introducing first the concept of statements, the video goes on to...

Tired of printing in 2-D?. An informative video explains the basics of printing in three dimensions. It goes on to point out some of the fun and practical applications the new technology offers. 

Let's move into the third dimension! Learners explore the vocabulary and notation related to three-dimensional figures. The video covers examples of pyramids, but the vocabulary is universal to all 3-D objects.
