Lesson 3
Commands & Parameters
The Foos Chapter 2 & 3
Time:
45-60 min
Materials:
Tablets or computers with “The Foos"
1 set of the Commands & Parameters cards for each student
Pencils and paper
Learning Goals:
Learn what commands are and how they can be modified with parameters.
Learn that commands are the primary instruction while parameters are the details –
For example “walk” is a command and “left” is a parameter.
Vocabulary:
Command: primary instructions that tells the computer what action to perform (e.g.,
run, jump, walk)
Parameter: details of instructions that adds more specific information about the
command (e.g., direction, color, object to perform an action on)
Introduction:
Introduce the concepts of commands and parameters by asking the class to tell you
the directions to get from your classroom to the library. Tell students to be specific
and make sure to include things like the direction (left, right, up, down).
