Dash & Dot: Step By Step (Gr. 3-4)


Every task that we complete involves a series of steps in a particular order. In this lesson, students will learn that Dash and Dot also complete tasks in this way, using the algorithms that we give them.


  • Understand the term algorithm and relate computer algorithms to everyday tasks
  • Break down a problem into meaningful steps or instructions, in the correct order
