Unit 4 - Lesson 5-6
Lesson #5-6: Scratch - Moving Sprites
Provide a general overview the lesson. Include teaching tips here, if any.
This lesson is about students connecting Math coord plane to CS. Using Scratch: change sprite, glide, forever, flag, sound,
● Provide an overview of the various parts of the lesson (especially important if you suggest changing the lesson sequence)
● Then, list the lesson sequence. First activity - Second activity, etc.
Review with entire class the coordinate plane and how Scratch’s coordinates are numbered.
1. Establish connection of Coordinate grid to Scratch: Prepare overlay for class that demonstrates a coord grid and has some points and get students to name the points. Demonstrate to students where they can find the x,y coord values of their sprite as it is moved around the screen. Have them locate the origin.draw a point there color red, Next give each student a clear overlay and have them create a grid using vis a vis markers to show x and y axis.
2. Have students use markers different color to draw a maze, not too complex on the plastic overlay.
3. Have students code the glide command so that their sprite makes it to the end
4. Play applause as the sprite makes it to the end.
This works great as a pair programming project
Provide a brief overview the CS content covered in this lesson. Objectives
Students will be able to:
● Locate x, y positions of sprites
● Use the glide command
● Use the sound command
Materials and Prep
● Enough transparencies for students to draw their maze
● Vis a Vis pens
● Prepare a Scratch scenes for the coord grid, with points located
● Scratch programs with their maze glide code.
● Mazes on transparencies
Extension is to have students actually draw the maze with code line draw commands, it is great to have kids share their mazes and challenge eachother.
