## Mathematical Colors and Codes, Episode Five — More Codes with Nondecimal Bases

Episode Five of Mathematical Colors and Codes, my Virtual Program Series for the library is up!

Episode Five looks at more ways you can use nondecimal bases to make coded messages.

This video, like all the others has a downloadable coloring page. This one has charts for a Base Six Code and a Base Five Code.

Here’s this week’s video:

## Mathematical Colors and Codes, Episode Four — Color Codes with Nondecimal Bases

Episode Four of Mathematical Colors and Codes, my Virtual Program Series for the library is up!

Episode Four now takes the Nondecimal Base systems we talked about in Episode Three and uses them to make coded messages.

This video, like all the others has a downloadable coloring page. This one has a chart for choosing your own colors and making your own coded messages with nondecimal bases.

## Mathematical Colors and Codes, Episode Three – Nondecimal Bases

Episode Three of Mathematical Colors and Codes, my Virtual Program Series for the library is up!

Episode Three is the longest episode. (They do get shorter!) I talk about various bases and look at them together with prime factorization color charts. I’m hoping it gives kids a feel for how other bases work.

This video, like all the others has a downloadable coloring page. [Right now this is the incorrect link. I’ll fix it with the correct one tonight.] This one will let you see for yourself how prime factorization patterns change in other bases, as well as giving you a feel for how counting works in other bases.

## Mathematical Colors and Codes, Episode Two: Prime Factorization Codes

Episode Two of my Mathematical Virtual Program Series is up!

In Episode Two, I talk more about prime factorization and ways to show it with colors. Then I show how you can use that idea to make a prime factorization code.
