Unit 4.2
Digit dash
In this unit, students will design a game to apply their understanding of multiplication as a form of comparison. They will select sprites connected through a central theme and incorporate user input to control the motion of their main sprite, which will collect items to increase a score. Students will then personalize their game, adding variety and complexity to the behaviors of their items.
Overview documents
Selecting sprites
Students are introduced to programming in Scratch. They investigate an existing program where they modify the values within different commands. They then select their character sprites.
Make it move
Students investigate how motion commands move sprites on the Stage. They then use conditionals and sensing commands to move their sprite in response to user input.
Here come the clones
Students are introduced to cloning as a way to program multiple copies of a single sprite. They then create a program to create a set number of clones before returning to their game to clone their own items
Collect your items
Students examine interactions between sprites. They are introduced to variables as a way to track a value in a program. Finally, students modify their program so the score increases when an item is collected.
Add variety
Students discuss ways to make a game more challenging. They modify their program so certain sprites have a larger points value and are more difficult to collect.
Arithmetic arcade
Students add instructions for their game before sharing their work with a peer. They then showcase their game and provide feedback to one another.
