Lesson 3

Here come the clones

In this lesson, students explore cloning as a way to program multiple copies of a single sprite. Through a Parson’s Problem, they create a program to make a certain number of clones. Finally, they return to their game to program the motion of their item sprites.

Standards

CSTA Standards

  • 1B-AP-10: Create programs that include sequences, events, loops, and conditionals
  • 1B-AP-11: Decompose (break down) problems into smaller, manageable subproblems to facilitate the program development process.
  • 1B-AP-15: Test and debug (identify and fix errors) programs.

Common Core Standards

  • CCSS.MATH.CONTENT.4.OA.A.1: Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
