Class Experience

Students will learn how to use the old style Roman Numerals and do calculations on a counting board style abacus.

If you have an abacus, you're welcome to bring it to the class to share. 

We'll play a small dice game to grow familiar with the counting board and Roman numerals, then we'll discuss patterns we see and how we can apply those patterns when we do mental arithmetic. 

In the second class we'll look at different ways to use different abaci.

Profile
Teacher expertise and credentials
I am a homeschooling mother of three. I have a B.A. in political theory and many years experience teaching online. I've also studied theology and written a book titled A Secular Bible Study as well as a young adult novel titled The Edge of the Circle. I teach online classes about secular Bible studies, piracy, Tudor England, and Victorian Britain.

A few years back I asked one of my sons what he wanted to do for a unit study, and he said he wanted to know more about pirates. He didn't want to know about their lifestyle but why they went to sea. That led me on a multiyear quest to learn everything I could not just about pirates but the time period they lived in, from the mid 1400s to early 1800s. Someday I'll publish the manuscript I wrote while reading about this. In the meantime, I love teaching classes on it.

I love reading. I love talking about what I've read. I love discussing the big questions that one can find buried in a children's book or underlying a piece of poetry. I want to understand the different interpretations of abstract concepts like justice and to ask why good things happen to bad people. I love to read everything I can to see how people throughout history have wrestled with the big questions.

If you're trying to figure out which of my secular Bible study classes to take, the main differences are the age range and the class format. I offer classes for younger students and for older students. I also offer multiweek classes or ongoing classes. The multiweek classes allow me to start at the beginning and proceed in a logical format, but they require a commitment from students. The ongoing classes jump around according to student requests and not everyone will have the same background knowledge. However, they do not require student commitment.

When I'm not teaching, reading, writing, or talking with my children I'm working on crafts. I like to do embroidery and beadwork. I crochet. I'm learning to sew.
