We cover how to convert from decimal to other number systems (binary, octal, and hexadecimal) and back to decimal.

We discuss how colors are represented in computers through hex codes. We learn faster tricks to convert from binary to octal and hexadecimal and from octal and hexadecimal back to binary.

We review conversions between different bases and learn how to add and subtract numbers in different number systems.

We review the concepts for this contest, including conversions between different bases, color codes, and arithmetic operations. We go over sample contest problems on number systems from upper divisions.

Students can choose to take Contest 1 during today's lesson.

We learn about prefix, postfix, and infix notation. We review the order of operations (PEMDAS) for infix and learn how that relates to prefix and postfix. We practice converting from infix to other notations and evaluating prefix/postfix expressions.

We review how to evaluate prefix and postfix expressions. We go over practice problems for converting from infix to prefix notation or postfix notation. We introduce how to convert from prefix or postfix back to infix using information about the order of operations, which will help us convert between prefix and postfix.

We will go over more practice problems to convert between prefix and postfix, being careful that we are preserving the order of operations in the original expression.

Today will be the last class that we will be using to focus on Contest 2. I plan to allocate the first 30 minutes to a practice test, the next 15 minutes for reviewing the solutions to the practice test, and the last 15 minutes for introducing boolean algebra. If your child has already taken Contest 2, then I will have them read an article about boolean algebra. During the first 30 minutes of class, anyone reading this article will be able to send me any questions they have through the chat feature in GoToMeeting. By the end of the week, I would like everyone to have taken Contest 2 on HackerRank, though you technically have until March 7th to complete it.

During this lesson we'll cover truth tables as well as not, and, and or operations. After today, students should feel comfortable answering the first three questions of any given Contest 3 practice test.

Hope you are enjoying the beautiful weather outside! Today, I plan on teaching simplification techniques and tautologies.

Today I will begin by reviewing the HW from last week. Then, I will quickly review simplification techniques as well as equality. Afterwards, students should know all material necessary to score a 5 on contest 3. Time permitting, we'll also have a competition where the top three highest scoring students will receive a shoutout in this chat :D

Hi everyone! Today we'll begin by reviewing any questions that students might have. Afterwards, we'll have another competition with a set of new contest 3 questions!

Today we begin to explor Graph Theory, which involves identifying some special kinds of graphs and calculating cycles and paths by hand.

In today's class we'll continue learning about graphs, including methods for analyzing paths and what it means for a graph to be connected and / or complete.
