Chapter 3 / Level 4: Constants and Practice

Teaching Objective:

• Student learns what constants are and how they are used
• Familiarizes themselves with variable division
• Practices form and syntax with operators

Guide

Have the student use the constant egg_basket to store eggs in containers. Create two variables named bag1 and bag2 and store half the eggs in each bag using operators.

bag1 = egg_basket/2
bag2 = egg_basket/2

Walk to the three X marks in front of each container, face the containers and use the place() function to store them.

player.place(bag1)

........

player.place(bag2)

Walk to the next X mark in front of a table and use the speak() function to express the amount of eggs inside the egg_basket as detailed in the tutorial.

player.speak("there are %d eggs" % (egg_basket))

 ........

player.speak("there are %d eggs in bag 1 and %d in bag 2" % (bag1, bag2))
