How I reviewed the material: I spent about 30 ?35 minutes using the software and trying out different features. I used three different manipulatives.
My evaluation of content quality: The scope of the content was quite amazing. I copied the grid that helped a user get to the section that they need. In each category/grade level there are from three to eight activities. One activity might show up in as many as three grade levels.
The most complete lessons have a teacher?s lesson planner, academic standards reference and a Help tool. The standards are linked to the NCTM (National Council of Teachers of Mathematics) standards web-site.
The manipulatives run well on the computer. Some ?fine touches? on the UIF (User Interface) would be nice. For example, there is a simulation of adding in base 2, 5 or 10 and the column headers remain at 1, 10, 100 with 2 or 5 in small letters under it.
My evaluation of effectiveness for teaching or learning: I think this would be a good center activity. Probably would have some of the more computer savvy students go through the manipulative exercise and give me an evaluation and things that I might need to know to have other students use it. Then I could get on and go through it myself.
My evaluation concerning ease of use This is written in Java Script and seems to have fairly severe UIF capabilities, but it is NOT clumsy, but neither is it totally intuitive. Must read the instructions to get a feel of it?no bubble help or graphic support. It?s a pretty boring presentation format, compared to math websites for kids, but it seems more serious and involved, so it?s a great tool.
