Unit Description
Welcome: Students will get a sense of what this course is about and will reflect on what they hope to get out of it.
Introduction to Programming with Turtle Graphics: Students learn Python commands, functions, and control structures by drawing shapes on their screen and solving puzzles with Turtle Graphics!
Basic Python and Console Interaction: Students will learn the basics of programming by writing programs that interact with users through the keyboard!
Conditionals: Students teach their programs to make decisions based on the information it receives.
Looping: Students learn how to write more efficient code by using loops as shortcuts.
Functions and Exceptions: Students learn how their programs can be decomposed into smaller pieces that work together to solve a problem.
Strings: Students use more sophisticated strategies for manipulating text in their programs - slicing, concatenating, and formatting.
Creating and Altering Data Structures: Students learn how tuples and lists are formed and the various methods that can alter them.
Extending Data Structures: Students learn to build more complex programs that make use of grids and dictionaries.
Project: Guess the Word: Students use the skills they've learned throughout the course to build a word guessing game.
Final Exam: Students prove their knowledge of content learned throughout the course through a multiple choice, short answer, and programming exam.
