Changing Size (Lesson 3)

Introduction

New Code Blocks

Objectives

• Use Pen commands to create a jumping game
• Use code blocks to change the size of Actors

Warm-Up (15 minutes)

• You’re going to learn two different ways to change the size of an Actor using Tynker!
• Think about video or computer games where a character or object changes its size.
  * For example, perhaps an object increases in size during a boss scene, or maybe an object increases in size as it gets closer to a character.
• What other scenarios can you think of where a character or object in a video or computer game changes its size?

Activities (45 minutes)

• A space alien introduces the “change size by” code block. Emphasize to students that p
  ***positive values will make the Actor bigger
  ** while negative values will make the Actor smaller
• Click the different “change size by” blocks to see how different values affect Codey.

• In this module, you will play a completed Jump Enemy Lines project, where you’ll need to avoid touching the purple laser! You’ll create your own version of this project in the next module.
• Click the red stop button to move on to the next module.

• In this DIY (do-it-yourself) module, follow step-by-step directions to program a racer to jump over the line of another racer.
• How to play:
• On Web: Control the racer by holding down the mouse button, and make the racer jump by pressing the spacebar.

• To solve this puzzle module, need to program the racer to jump over enemy lines. Collect three orbs and avoid the enemy lines to win!
• Give a hint: Tell students to attach a “forever if” block below the “on start” block.
• Optional: Ask students, “Which pen block makes the racer start drawing?” (“pen down”)

• In this module, watch a completed Change Size project. you’ll create their own version of this project in the next module!
• Tell students to click (web) or tap (mobile) the cars and watch how the size changes.

• In this DIY project, program car Actors to grow or shrink when clicked on (web) or tapped (mobile). you will also learn two different ways to use the “change size by” and “set size to” code blocks.
• Describe the cars’ size differences as you grew or shrunk.

• answer 5 multiple-choice questions to review concepts from this lesson.

Extended Activities (10 minutes)

• What are two different code blocks we can use to change the size of an Actor
  (“change size by” and “set size to”)
• What pen block makes an Actor draw?
  (“pen down”)
• Describe a situation when we could use the “pen down” code block
• What pen block makes an Actor stop drawing?
  (“pen up”)
• Describe a situation when we could use the “pen up” code block
• Give an example of positive values?
• True or false: Using a positive value inside a “change size by” code block will make the Actor bigger.
• Give an example of negative values.
• True or false: Using a negative value inside a “change size by” code block will make the Actor smaller.
