Kelly Lobera on 13 Sep 11Overview: This site is so cool; I wish i knew about it earlier. I was refered to it by my current math professor because we are discussing manipulatives in his class now. Manipulatives are usually the little blocks and shapes kids can use for learning math. On this site, they have a huge variety that extends beyond that. It can be used by students of all ages and of any skill level. Content: This site has a huge library of different manipulatives broken up by the age group that would most likely use them. They also have some information about the site and how it came about. I had no problem accessing any aspect of the website. Design: The site is really easy to use. The first thing visible when you open the site is a big grid breaking up the manipulatives by grade level and the sub-subject of math it deals with. All you need to do to access the manipulative you want is click on the square in the grid that it corresponds to and find exactly what you want on the big list. I think something that could improve the site would be to include a better discription of each different manipulative. While it is easy to navigate and well designed, I think the site could have been made more aesthetically pleasing.
