Many important topics in computer science can be taught without using computers at all. This series of activities unplugs computer science by providing off-line activities, games and puzzles that are suitable for people of all ages and backgrounds, but especially for elementary school children. The activities cover a wide range of topics, from algorithms to artificial intelligence, from binary numbers to boolean circuits, compression to cryptography.

There are currently two versions of the book. The one on this page is the "Teachers' Edition" (red cover), which is aimed at people with less of a technical background. It has 12 activities, and a lot more illustrations and handouts. The "Original" version (blue cover) is aimed primarily at readers with a more technical interest. It has more activities (20 in total) but fewer illustrations. We recommend that you preview the two books to decide which is most suitable for you.

Comfortable and complimentary
Size: 11, Color: Brown
The shoes are very comfortable and easily broke in after two wears. I get several compliments on them daily, and others have purchased them after seeing mine. I also have the black pair, but the brown ones are my favorite. Sizing is true to size, an excellent value for your money, and they are lightweight and breathable. The soles are thick, which makes them extremely comfortable.

Comfy and non slip! Amazing!
Size: 9.5, Color: All Black
I work 12hrs sometimes on my feet. These shoes are amazing !!! Broke them in on a 10hr shift and they feel like walking on pillows. My feet were comfy and not throbbing. I felt the difference in the non slip in the kitchen and I’ll say it outright……. Worth the $40! I got the brown coming and I’m assuming they’ll be just as comfortable. Bruno Marc’s are great!

Nice but not ideal sizing.
These look nice. They do not have a traditional tongue, replacing it with some sort of elastic lining. They do fit larger than expected. I purchased wide since normally need that and it creates a bump just below the laces. Also, after size 11 there are only whole size increases. I feel an 11.5 regular would have fit better. They are pretty comfortable with a cushiony insole and thick sole.

Slip ons worth slipping on…
Size: 9.5, Color: Black, Size: 9.5, Color: Black
Very stylish and comfortable. I love how light they are because I’m on my feet all day. The black leather is very deep and very rich. The elevated sole gives me a tad more height, too…which I like. And yes, they’re slip ons. Don’t let the laces fool you. For under $40, these shoes are a strong value to consider…

I feel I’m walking on clouds
Size: 10, Color: Brown
I’m on my feet 6–8 hours a day working at the dealership, constantly walking the lot and helping customers—and I’ve gone through a lot of shoes trying to find something that actually holds up. These Bruno Marc MaxFlex Dress Sneakers honestly surprised me. They look sharp and professional enough for work, but feel more like a comfortable athletic shoe than a stiff dress shoe. From day one, there was no break-in period, no soreness, just all-day comfort. I feel I’m walking on clouds! If you’re in a job where you’re standing or moving around a lot but still need to look polished, these are hands down the most comfortable work shoes I’ve owned.
