Coders revisit a previously created project about a dance party to add a short story about travelling to the dance party. The purpose of this project is to apply newly acquired understandings to a prior project.

Coders engage in a multi-day project where they create the introduction to a short story and then pass their project on to be finished by their peers. The purpose of this project is to encourage young coders to communicate and learn from their peers.

Now we are ready to calculate an intersection point using our ray CP (parametric form) and our line AB (slope-intercept form).

Now that we have a feeling for constructing permutations let's introduce the factorial formula to make counting them easy.

In this video we'll uncover the connection between the previous diagram and the rotation formulas. Repeat viewing suggested!

Step by step instructions to print numbered dice for games using a 3D printer and TinkerCad design.

Design and create your own custom, 3D printed zipper pull! This project utilizes Tinkercad and some simple tools.

Students learn how 3D printing, also known as additive manufacturing, is revolutionizing the manufacturing process. First, students learn what considerations to make in the engineering design process to print an object with quality and to scale. Students learn the basic principles of how a computer-aided design (CAD) model is converted to a series of data points then turned into a program that operates the 3D printer. The activity takes students through a step-by-step process on how a computer can control a manufacturing process through defined data points. Within this activity, students also learn how to program using basic G-code to create a wireframe 3D shapes that can be read by a 3D printer or computer numerical control (CNC) machine.

Coders use the start on green flag block to create a silly dance party using motion blocks. The purpose of this project is to introduce young coders to adding sprites in code and triggering algorithms with the green flag in ScratchJr.

We can use de Casteljau's algorithm to calculate curves using any number of points.

Let's take a closer look at the weights used during subdivision. Do we have to be careful when selecting weights?

Let's look more closely at how light bounces when it strikes an object. We'll cover reflected and refracted rays.

Are we really creating parabolic curves using this construction? Let's gain some insight first.

Use an array to store many objects as well as create any shape you can imagine. Click here to review objects.

Now you can start scaling your shapes to make your lamp look younger.

Now you are ready to start subdividing your own shapes with more than 4 points!
