Lesson Overview

This lesson introduces the final component of the unit's model of computing: storage. After trying out
an "outfit picker" app, students discuss what information should be stored in the app versus input
every time the app is run. They then look at a series of apps and use their decisions about what
should be stored to create guidelines for deciding what information to store. They then review the
four components of this chapter's model of computing: input, output, storage, and processing.
Afterward, they have one last opportunity to revise their decisions about which items should be
classified as a "computer" from earlier in the chapter. The lesson ends with a reflection on their own
app ideas and how storage could be used.

Go on Code Studio to look at the outfit picker app.

● What is one input, one output, and one kind of

processing it might use?

● If you used this app every day, what information

would you want it to remember?

Guidelines for Storage

In your groups, brainstorm at least two guidelines about what
types of information should and should not be stored.

“If the information ______________, then that information
(should / should not) be stored because _____________. For
example, ____________ (should / should not) be stored.”
