Scratch Part 1
Introduction to Scratch, and Drawing Sprites in Bitmap and Vector mode.
Drawing Lesson 1: Intro and Bitmap Drawing
To introduce students to Scratch Computer Programming.
To learn how to draw sprites in Bitmap mode in Scratch.
To draw a practice Sprite in Scratch using Bitmap mode.
How many of you have used Scratch Before?
Watch a short video about Scratch.
The Story of Finn by Marco
Let's talk about sprites (can move) vs. backdrops (are always in back, don't move)
Learn how to use the Bitmap Drawing Tools.
Learn how to draw and name a sprite.
Changing the size of your sprite
Saving to your backpack.
- MACS: username: lab, password: smart
- SCRATCH: Sign in with username: steamart#, password: future
- Write username and password in your art folder.
- Answer all questions.
- Draw a Practice Sprite in Bitmap Mode (Draw an object)
- Name your sprite
- Experiment with all the bitmap drawing tools.
Save the Sprite to your backpack.
Save your project and Sign out
If you like using Scratch, you can use it at home at scratch.mit.edu/
Drawing Lesson 2: Vector Drawing
Objective: To learn how to draw sprites in Vector mode.
Activator: At your tables, look at your comics. Decide what should be sprites, and what should be part of a backdrop. Why? Someone from each table will report to the class.
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?
- Draw your superhero 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.
Create another sprite, or more costumes. In what creative ways can you animate your sprite?
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.
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
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?
Drawing and naming backdrops.
Title Backdrop (visual Hint about your story)
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.
