Unit Map

Students explore foundational concepts related to solving problems with computers. (50–60 min.)
The class reads a storybook in which Hikaru and his friends program an automated system to help the toy store handle more customers. Students also explore writing an algorithm to move a train around a gameboard. (55–80 min., 2 sessions)
Students investigate how to use the BBC micro:bit to receive input and produce output. (90–120 min., 2 sessions)
Students work together to create an automated train signal. (45–60 min.)
Students follow the steps of the Engineering Design Process to imagine, plan, create, and improve an automated system to increase the efficiency or safety of a home. (90–120 min., 2 sessions)
Students extend their computational thinking skills to mathematical concepts as they practice strategies for multiplication and division. (50–70 min.)
