-
This is a great activity to use when Teaching with Processing because you can create a follow-up assignment to turn the pseudocode into Processing.
-
In order to do this, use this activity after students learn to draw shapes in Processing.
-
Activity:
-
Give students a picture of 5 shapes (like boxes, circles, or rectangles) that you want drawn.
-
Ask students to explain to a partner how to draw this picture.
-
Students will often say things like "do it again."
-
Next, ask students to create a more formal definition.
-
Then, have write down their instructions using pseudocode.
-
Once students have pseudocode, introduce the syntax necessary for creating a for-loop.
-
Ask students how they can change their pseudocode to include the new concept of for-loops.
- The goal of this assignment is to transition from students explaining action as "do it again" to using for-loops.
