Drawing Lesson 1: Intro and Bitmap Drawing
Objective:
To introduce students to Scratch Computer Programming.
Activator:
How many of you have used Scratch Before?
Mini Lesson:
Watch a short video about Scratch.
Student Engagement:
LOGGING IN:
- Chromebooks: login with your school emails
- Go to scratch.mit.edu
- SCRATCH: Sign in with username: ##amber or ##pur

Drawing Lesson 2: Vector Drawing
Objective: To learn how to draw sprites in Vector mode.
Activator: Introduce activity? If you had STEAM/Art last year: Draw a vector sprite and create a program: you have three class days to complete it.
Mini Lesson:
Why do we want our sprites to have costumes? - to animate your sprite - to have a new pose - to be able to duplicate and edit a sprite.
Learn how to use the vector drawing tools.
Tip 1: Later we will program your sprite to change size and direction. Do not create costumes for this.
Tip 2: What happens when you convert between the two drawing modes?
Student Engagement:
- Draw a sprite in vector mode.
- Create costumes for your sprite.
- Name your sprite and costumes.
- Experiment with all the vector drawing tools.
Wrap-up: Save your sprite to the backpack. Save your project. Sign out.
Extension:
Create another sprite, or more costumes. In what creative ways can you animate your sprite?
Fun Fact:
What is the difference between bitmap and vector images? Bitmap (or raster) images are stored as a series of tiny dots called pixels. ... A vector image just has to store the mathematical formulas that make up the image, which take up less space. Vector images are also more scalable than bitmap images.

Drawing Lesson 3: Compare and Contrast Bitmap and Vector Drawing
Objective: To learn the pros and cons of Bitmap mode and Vector mode. Learn how to program your sprite to switch costumes. Learn how to save your sprites to your backpack.
Activator: What are at least two differences between vector and bitmap drawing in Scratch? Write in your composition books.
Mini Lesson:
Create a chart of pros and cons.
Student Engagement: Work on vector sprites. Make sure to put them into your backpack.
Wrap-up: Share your sprites with the class. (Walk around to look at Sprites.)

Drawing Lesson 4: Backdrops
Objectives:
To learn how to draw a backdrop. To learn how to name backdrops.
Activator: What do you think the differences might be between a sprite and a backdrop?
Mini Lesson:
Drawing and naming backdrops.
Title Backdrop (visual Hint about your story)
Ending Backdrop
Four setting backdrops.
Student Engagement: Draw your backdrops.
Wrap-up: Save and sign out.
__________
Make sure all your sprites and backdrops are named. I'll check today.
Save copies of sprites and backdrops in your backpack.
