Codey Rocky - Loops D4: All Shapes and Sizes

Description

In this lesson, students will use loops drive in multiple shapes and patterns of their choosing. While driving, Codey Rocky will draw the shape on it's screen.

Objectives

• students will be able to describe what a loop is

• students will be able to program a loop using Codey Rocky

• students will be able to program their Codey Rocky to drive

Sequences and Loops

Review sequences and loops by having student replicate the previous activity. Create a square on Codey Rocky's screen and have Codey Rocky drive in a square at the same time using a loop, like the code below:

Connecting to mBlock 5

Introduction to mBlock 5

Project your computer screen and open the mBlock 5 program. Point out the icon and how it can be found in your specific system or device. Discuss the wireless dongle and how it is used to connect a specific Codey Rocky to a computer. The dongle is required for the Codey Rocky to be connected to the computer, so keeping that dongle safe and with the proper Codey Rocky is very important.

(Optional) Work with the class to label their dongle and device if they are not labelled already. These can be permanent device identifiers using a label maker (i.e Codey Rocky 1) or have the class temporarily name their Codey Rocky and label it with a sticky note or piece of paper and tape. (even if a device has a permanent label, it is always fun to allow students to name their devices)

Model connecting Codey Rocky to mBlock 5 by performing the following steps:

• Turn on Codey Rocky

• Open mBlock 5 if it is not open already

• In the area where it says "Connect your Device" click the BLUE connect button.

• Plug in the USB dongle.

• Select the USB dongle from the drop down. It will be listed as "/dev/tty.wchusbserial14xx" with the last two number being different depending on the port the USB is plugged in to (ex. 1410, 1420)

• You will know the device is connected when the window in mBlock 5 changes, indicating a proper connection and your ability to now upload code to Codey Rocky.

(Optional) Have students connect and disconnect their Codey Rocky from mBlock 5 a number of times to practice the process so they can do it independently going forward when instructed.

All Shapes and Sizes

Say "Now that we have done a square, let's see what other shapes you can draw and drive with your Codey Rocky. What other shapes do you think you might be able to create using a loop?"

Shapes they could come up with include:

• Triangles

• Octagon

(Optional) A circle can also be driven using a loop. If there are students who seem to be excelling, challenge them further by having them try to draw and drive in a circle using a loop.

Move around the room observing and assisting as needed with their code and mapping out the dots.

Wrap Up

Say "By far the two most important concepts in programming are sequences and loops. Now that we have a handle on how Codey Rocky can draw and move, and how we can use loops to repeat sequences over and over, we will build on that to do other things! In the next few lessons, we are going to learn how to make Codey Rocky sing!"
