What datatypes have you seen so far? Can you think of Number values? String values? Image values? What are some expressions that evaluate to a Number? How about the other datatypes?
Before introducing a new datatype (Booleans), this would be a good time to quickly review the three major contexts students have learned for working with expressions: Circles of Evaluation, Contracts and Design Recipe. In this lesson, students will apply each one of them to Booleans, discovering that everything they’ve already learn still applies - even in the new type.
