Changing Pen Color (Lesson 4)

Introduction

New Code Blocks

Objectives

• Use Pen commands to create projects
• Create an Etch A Sketch©-style project

Activities (45 minutes)

1. Race Car Example (Example)

• This module is an example of a completed Race Car project. you create your own version of this project in the next module!
• How to turn the race car: Tell students to use the arrow keys (web) or tilt your device (mobile).
• you need to click or tap on the Stage to stamp the Actor.

• In this DIY (do-it-yourself) project, you program a racer to move forward and respond when the left and right arrow keys are pressed (web) or when your device is tilted left and right (mobile).
• Did students finish early? Direct your attention to the bonus activity in “Step 4" of the tutorial, which encourages them to modify your code and make the racer move faster or slower!

• you view a completed Doodle Racer project. you’ll create your own version of this project in the next module!
• Optional: Ask students how the doodle racer is different from the race car from the previous module. (The doodle racer leaves behind a colorful trail.)

• In this DIY project, you program a racer to leave a pen trail of different colors!
• Optional: Encourage students to create fun, colorful geometric shapes using your doodle racer!

• To solve this puzzle module, you need to use the “set pen color” and “broadcast” blocks together.
• Give a hint: Tell students that the pen color must be set to the correct color before using a “broadcast” block.

• In this module, you watch a project of two racers drawing an ice cream cone. you’ll create your own version of this project in the next module!

• In this DIY project, you follow the tutorial to program a racer to draw a circle and a square using pen drawing. Note: If you complete the code exactly as suggested, the circle and the square drawn by the racer will overlap.
• Bonus: Encourage students to modify your code and create more geometric drawings using simple shapes!

• you watch a completed Etch A Sketch© project where a spaceship draws on the Stage! you’ll create your own version of this project in the next module!
• Check that students are pressing the arrow keys (for web) or tilting your device (mobile) to draw on the Stage.

• In this DIY project, you program a racer that you can control using arrow keys (web) or tilt controls (mobile). The racer will draw a lined trail where it travels, similar to an Etch A Sketch©! Additionally, you program the racer to change the sketch color.
• How to play:
• On web: Control the racer using the arrow keys. Use the spacebar to change the pen color.
• On mobile: Control the racer using the tilt sensors. Tap on the screen to change the pen color.

Extended Activities (10 minutes)

• Choose an object (e.g., Tetris pieces, city skyline) that you can draw using your Etch A Sketch© project.
• Share your drawings with the class.
• What cool works of art did you create?
• Did you modify your project or experiment with your code?
