Overview

Students learn to write functions that calculate and return values, first through an unplugged activity by playing Go Fish, then by practicing in Code Studio, and finally by writing functions that return values in a simple turtle driver app.

Vocab

• Return Value - A value sent back by a function to the place in the code where the function was called from - typically asking for value (e.g. getText(id)) or the result of a calculation or computation of some kind. Most programming languages have many built-in functions that return values, but you can also write your own.

New Code
