A great site full of rich information.  Easy to find information.  I looked through some of the algebra pages and found them to be informative and useful.

I actually did a lot of reseacrh on the abacus and the barcode links. I am a bagger and i always wondered about the barcodes. Now i am informed. I do like the exercises that are offered. they are placed after a certain subject is explained. Sometimes they are included in the detailed explanation. I like to have that becuase its like a school lecture. u get a formula and leanr how its used, then teacher gives u a problem to solve form what u just leanred.
Time spent reviewing site: I spent about 20-30 minutes reviewing some of the links within this site.

Looking over this material was a little bit overwhelming because i didn't know where to start but,it would be easier if I knew what I was looking for.I looked it over for about 20mins and got dizzy.The content was overall easy to look for because everything was in alphabetical order.Teaching would be a little bit harder because I'm not good at math myself,if there was someone who wanted to learn more about it.It would probably be much better for them.It was easy to learn because there were steps by steps for you to follow.It was easy to use some of them, if you knew atlest some of the material.

Interactive Mathematics--Arithmetic/Algebra is one of the helpful link I found on this website, particularly the "fast Arithmetic Tips" mental calculations. The examples and explanation really helps me improve my math. I will forward this link to my son so he can review and study math using this link.

1. I reviewed the material by trying out some of the games and puzzles applets the site had to offer. For example, I played a game called “A Game With Coins” which I ended up winning multiple times. I spent about a half an hour running through different applets. 2. The quality of content on http://www.cut-the-knot.org/ is very good. All of the games and puzzles accurately present concepts and models that are educationally significant by allowing the student to try problems hands on through the use of java applets. These java applets indicate whether you win or lose and each applet is accompanied by discussions and explanations of the math involved in trying to solve the problem. 3. Cut the knot dot org has tremendous potential for learning and enhancing teaching by providing a plethora of material in the area of arithmetic and algebra to discuss and assign to students for homework and in class discussion. 4. For me, using the materials presented to me was very easy. The site mainly uses java applets to illustrate a math game or puzzle which work in conjunction with an internet browser. Most browsers are enabled to do this and if not the browser directs you to Sun’s website where you can download the appropriate software which is very easy to do. Chances are, if you are on the internet browsing sites, you have java installed and enabled to work with your browser.

I looked at several Interactive Tools that this page provided, some of them are
the java interactive games such as #60 "Flipping Pancakes" or # 23 " Breaking
Chocolate" as well as # 1 "3 Glasses" I tried those 3 interactive items out and
found them quite mind boggling and interesting since it took me a while to get
what the website wanted right.

This website is very easy to understand and can definately be used as a teaching
tool in a math class for students that have very bad math skills.
Used in course? Yes
