Students will study chapter 12 from the course book.

7/9/2023

Students will study a few games as an intro to game theory.

7/16/2023

Students will play a few more games trying to figure out a winning strategy. Then they will take a quiz to assess their understanding of the covered material. If time permits, students will start chapter 19 from the course book.

7/23/2023

Students will study chapter 19 of the course book.

7/30/2023

Students will study chapter 20 of the course book.

8/6/2023

Students will study chapter 21 of the course book.

8/13/2023

Students will study chapter 22 of the course book. If time remains, they will start chapter 23.

8/20/2023
8/27/2023

Students will study chapter 23 of the course book.

10/1/2023

Students will review Roman numerals and then study lesson 18 from the course book.

10/8/2023

We will talk about binary numbers and the balance scale. I will also review how to do addition and subtraction using an abacus.

10/15/2023

We will finish Chapter 19 on pan balances, and begin Chapter 20, using the balance pans to introduce the idea of binary numbers.

10/22/2023

We will use the pan balance to motivate defining and working with binary numbers.

10/29/2023

We will follow Chapter 21, studying the method for writing numbers in binary form.

11/5/2023

Chapter 22 and quiz

11/19/2023

After finishing our review of Chapter 22 (counting triangles), we will work through Chapter 23 -- bits and digits.

12/3/2023

We will review some counting problems. Then we will discuss the differences and similarities between decimal and binary numbers (Chapter 23).

12/10/2023

We will cover Chapter 24 (odd and even numbers). Students who finish the chapter will then play a mathematical game in pairs.

1/7/2024

We will finish our class on odds and evens (Chapter 25, with a review of 24.15), and then we will demonstrate some binary mathemagic!

1/14/2024

We will cover the binary magic trick from Chapter 26 and 27.

1/21/2024

We will finish the binary magic trick (Chapter 27), and start to think about how to make arithmetic work with binary numbers (Chapter 28).

1/28/2024

The abacus will help us to visualize arithmetic -- addition and subtraction -- of binary numbers. At the end of the class, parents are invited in for a demonstration of the binary magic trick that students have been practicing.

2/4/2024

We will finish our discussion of binary arithmetic (addition and subtraction, Chapter 28), and then look at how binary coding can be used to represent letters as well as numbers (ASCII, chapter 29). We will not have a quiz.

2/18/2024

We will study the differences between orientable and non-orientable surfaces. Students will make their own Mobius strips and study what happens when the strips are cut. We will follow Chapter 30 from the workbook. Students should each bring with them a pair of scissors that they are able to safely use.

2/25/2024

We will start with a short quiz on binary numbers, odds and evens and the balance scale. Then we will start the topic of coordinates (Chapter 31).
