Presents a calculator with only a few numbers and functions that work, and asks the user to generate the numbers 1-15 with the limited functionality. On the same page is an article about the use of calculators when teaching math, and about innumberacy in general.
I am a college student and future teacher of mathematics. I spent about a half an hour reviewing the site and material it had to offer. I believe calculators are sometimes overused at a lower level, and yet they can be helpful tools at higher levels. I enjoyed the concepts presented, and used the broken calculator to my pleasure. I think this would be an appropriate learning tool.
First time users will find it easy to use the software whether they are familiar with computers or not.

Hello: I'am currently a college student. I review the site for about 60 minutes. I played with the broken caculator for a while. Once you start with the caculator before you know it an hour went by. This site would be a good educational tool.
The site was easy to navigate and to use the site you don't have to be a computer master. Overall the site was organized well.

I am currently a college student. I viewed the website for about a half hour. I used the site for two reasons: the first was the read out calculators and there affect in the class room and secondly to play the broken calculator game. The material was very easy to use and understand. I believe the material was very educational and would be a great teaching tool for students. I would show them how students use to do math with out a calculator.
The material was very easy to use. The calculator was broken but that was the point of the site. I had no problems with the navigational links. To use the material in the site you don't need any outside assistance. Overall this site was well organized.
