ACSL Elementary

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 introduced Contest 2 concepts relating to prefix/infix/postfix notation. For this class, I will begin by reminding students of PEMDAS/order of operations, and then I will transition into converting from infix to prefix, infix to postfix, etc. Near the end of class, I will review 2017-2018 elementary Contest 2 problems with students, with any unfinished work being assigned for homework.

Finished reviewing the two contests’ worth of material that I’ve distributed so far. Afterwards, we’ll try a couple practice problems, and then finally I will talk about WHY prefix/ postfix notations are more advantageous for machines to use

Today I will begin by reviewing how computers process prefix/postfix notation. Afterwards, we will go over the solutions to last week’s HW, and then we will look at contest 2 problems from last year

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