Grade 2Computational Thinker Coding Your Dream

DAY 2

Overview

Today I will add advanced coding elements and identify patterns in the code to debug any coding errors. 

Lesson

Today we will be continuing to add code to our Dream project.

STEP 1.

  Directions: Below are the Advanced Code Blocks Links to an external site. that we reviewed yesterday that you will be using for this project.

Motion Blocks (Blue Blocks)

Go Home  sends the Sprite back to its original start spot.

Sound Blocks (Green Blocks)

POP lets the Sprite make a Pop noise. Other sounds are also an option here.

Sound Blocks (Green Blocks)

Play Sound lets the programmer record a sound or text.

Looks Blocks (Pink Blocks)

Say Sound gives the Sprite a text bubble above their head.

Appear makes the Sprite appear.

Hide makes the Sprite hide from the scene.

Control Blocks (Orange Blocks)

Set Speed  sets the speed of the sprite movement.

End Blocks (Red Blocks)

End stops the code from progressing.

Go to Page  ends the code and then moves to another page. The number at the top right corner, is the page it will go to.

STEP 2. ADVANCED CODE

  Directions: Follow along with your teacher to add some of the advanced coding elements that we just learned about to your project.

  • Add in Pink Hide/Appear code blocks for objects/sprites that may have come back with you from the dream. 
    • Pink Hide and Show Blocks in Scratch Jr.
  • Add in Pink Say code block to add a speech bubble to a sprite telling something about their dream. 
    • Pink Say Block in Scratch Jr.
  • Add in Green sound code blocks to add your own words describing your dream
    • Green Sound Blocks in Scratch Jr.
  • Add in Orange Set Speed blocks to slow the movement of the sprite 
    • Orange Set Speed Block in Scratch Jr.

STEP 3. DEBUGGING

  Directions: People make mistakes all the time. Debugging is running code, finding the mistake, and fixing that code to run correctly the next time. Now that our dream code is complete:

  • run it (using the green flag) to watch the dream
  • note any mistakes in the code that need debugging
  • return to the page and the character/sprite and fix the code
  • run it again to check for any other bugs
