Logical expressions

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