Lesson Plan

Lesson: Keyboard Interaction
Time: 60+ mins

Introduction

In this lesson, students will program input controls to move Actors.

Code Blocks

  • : Run code attached to this block when you press a specified key.
  • : Change the x-coordinate of an Actor by the specified number of pixels.

Vocabulary

  • None

Objectives

Students will...
  • Use keyboard (web) or tilt controls (mobile) to move characters
  • Create unique controls to move Actors

Materials

  • Computers, laptops, or mobile devices (1 per student) with student account access to Tynker.com

Warm-Up (15 minutes)

Review the following terms with your students. They will use these in today’s lesson:
  • Horizontal axis (x-axis): The line on a graph or coordinate plane that runs horizontally (left-right)
  • Vertical axis (y-axis): The line on a graph or coordinate plane that runs vertically (up-down)
  • x-value: Horizontal (left-right) value along a coordinate plane
  • y-value: Vertical (up-down) value along a coordinate plane
Ask your students...
  • Have we seen these terms before? (Yes, in the "Jumping Over Obstacles" lesson)
  • Who remembers which code block we used to make the Actor move in the up-down direction? ("change y by" block)
  • Does the "x-value" move in the left-right or up-down direction? (left-right)
  • If we wanted to make an Actor move left or right, would we use a "change x by" block or a "change y by" block? ("change x by" block)

Activities (45 minutes)

Facilitate as students complete all Keyboard Interaction modules on their own:
1. Move to Collect Power Cells (Video)
  • Students will watch a short video that introduces the upcoming programming activity.
  • Optional: Read the captions on the screen to your students.
2. Move Back and Forth Example (Example)
  • Students will view an interactive project of Gus moving, which they will create their own version of in the next module!
  • Tell students to use their left and right arrow keys (web) or tilt their screen left and right (mobile) to move Gus.
  • Tell students to click the red button to move on to the next module.
3. Move Back and Forth (DIY)
  • In this DIY (do-it-yourself) project, students will program Gus to respond to keyboard (web) or tilt (mobile) commands!
  • Tell students that the "change x by" block uses both positive and negative values to make Gus move horizontally (left-right).
  • Check that students understand that the background doesn’t shift Gus to the left--his code moves him independently of other Actors (i.e., the Stage).
4. Move and Collect Power Cells (Puzzle)
  • To solve this puzzle module, students will need to program Gus to move back and forth to catch power cells!
  • Give a hint: Tell students to use a negative 10 value inside one of the "change x by" blocks to make Gus move backwards (to the left).
5. Make Actors Move Example (Example)
  • Students will view a project where the alien moves when arrow keys (web) or tilt controls (mobile) are used.
6. Make Actors Move (DIY)
  • In this DIY project, students will program an Actor to move up, down, left, and right using keyboard (web) or tilt (mobile) controls!
  • Remind students that the "change y by" block moves the Actor up and down, depending on the value inside the block. For example, a "-10" will move the Actor down, whereas a "10" will move the Actor up.
7. Quiz (Multiple Choice)
  • Students will answer 5 multiple choice questions to review concepts covered in this lesson.

Extended Activities (20 minutes)

Lead a mini-discussion with your students:
  • Who can list the four directions we programmed the Actors to move? (Up, right, down, left)
  • True or false: The "change x by" block moves the Actor up or down. (False)
  • How is the "change x by" block different from the "change y by" block? (The "change x by" block moves the character horizontally, whereas the "change y by" block moves the character vertically)
  • What is something you struggled with in today’s lesson? How did you troubleshoot the problem?
  • What is something you enjoyed about today’s lesson?
