Lesson details

Key learning points

  1. In this lesson, we will deepen our understanding of logical expressions by introducing the operators AND and OR. It will begin with a Parson's Problem to check our understanding of selection. It will then move on to an unplugged activity that introduces AND and OR. We will walk through code, and investigate it before writing our own logical expressions.
