I’ve been collecting resources for teaching Binary numbers and number systems lately. Today seemed like a good time to share what I have collected so far. And of course to ask people if they have others they recommend. MathmaniaCS Lesson Plan A lesson plan/activity for teaching Binary numbers from the MathamaniaCS web site. Includes a…

Interesting Links 15 February 2010

I’m running late today I am afraid. Got home late from the west coast last night and my body is a little confused about what time it really is. Make me think of the old song that asks “does anyone really know what time it is?” Any way it was all worth it as I…

Math, English, Binary, Computer Science, What a Mix

Some years ago a first year teacher (Name withheld to protect all involved) was trying very hard to teach Binary numbers for a group of sixth graders. It was not going well. Not at all. At the end of class, on the way out one student turned to the teacher and said “This stuff is…

Hiding Files in Plain Sight

Binary Number Game

I love binary numbers. I was first taught about different number systems in grade school and was fascinated with them immediately. I used to convert decimal numbers into different base numbers just for the fun of it.  So I guess it is not surprising that I love computer projects that involve binary, hex, and octal…

Binary, Hex, Octal - Does Anyone Care Anymore?

As the old joke goes there are 10 types of people in the world. Those who understand Binary and those who don’t. There seem to be fewer of those Binary understanding people in the world today. Or do I just ravel in the wrong circles? Does computer science really require a knowledge of different number…
