One of the main goals of Penjee is to make learning to program fun for kids, The main way that we do this is by making each ‘assignment’ a challenge. Here’s a walk through of one of the first challenges a student must attempt. We call this one “Grab() 4 fish And Avoid Water”.
Each challenge has a goal. In this assignment, you are asked to :
To grab() all 4 fish. However, this time, you must navigate around the water!
This challenge builds off the prior one which simply asked the student to grab() 1 fish (sans water) and not to worry about moving around the water.
SO, what does the solution look like? Well, a partial solution would start something like:
|
1 2 3 4 5 6 |
penjee = Penguin(0,0, east,0) penjee.waddle() penjee.grab() penjee.turn(right) penjee.waddle() // etc.. |
Ultimately, the student must write hand code to navigate the map as shown in the picture blow, in order to collect all 4 fish.
Every challenge has clear goals. In this case, we want to make sure that students know:
- that water is perilous.
- that the turn( ) method which can take either a left or a right parameter.
