10/3/2021

We will review binary numbers based on chapters 20 and 21 from the book.

10/10/2021

We will cover Chapters 22 and 23 from the book, including a brief review of Roman numerals. We will not be doing Quiz 6.

10/17/2021

In this class, we will finish comparing binary digits and decimal digits (Chapter 23), and start discussing parity (oddness and even-ness of numbers, Chapter 24). On the way we will find time for a brief review of Roman numerals.

10/24/2021

We will do Problem 23.21 as a warm up exercise, and then continue to Lesson 24, which is about Odd and Even numbers.

10/31/2021

We will review last week's homework and then continue to explore parity -- the idea of odd and even numbers -- following Lesson 25 within our workbooks.

11/7/2021

We will study lesson 26, in which we learn to use binary decompositions to perform a magic trick. From there we will review how to use the Russian abacus to represent, add and subtract multi-digit numbers.

11/14/2021

We will cover lesson 27, and practice our magic trick. Then we will review using the abacus to calculate sums and differences (from Lesson 15 and 16).

11/21/2021

In this class, taught by guest instructor Professor Kim, students will learn how to add and subtract binary numbers by modifying their abaci.

12/5/2021

We will finish up discussion of adding and subtracting binary numbers, and then take a recap quiz on binary numbers, odd and evens and Roman numerals. We will then discuss Chapter 29; using binary numbers to represent letters and characters. Finally we will learn how to play two mathematical games.

1/9/2022

We will review Chapter 30, the Moebius strip, as well as doing some problems that review some of the materials that we covered in the last quarter.

1/16/2022

We will cover Chapter 31, which introduces coordinates for the line and plane. Time permitting, we will do a review of Roman numerals.
