The intended purpose of this website is to have students review their knowledge in gathering and analyzing data, and using an Excel spreadsheet.

Overview: 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.

This website contains virtual manipulatives for all grade levels in Numbers & Operations, Algebra, Geometry, Measurement, and Data Analysis & Probability. These virtual manipulatives help the student understand the formulas, principles, and concepts in mathematics and science.

This website provides discussions and visualization activities to help students become more familiar with the data analysis.

Scott Chanthongthip on January 23, 2010 Overview: National Library of Virtual Manipulatives is a free website offered online to help teachers us visual aids to teach mathematics. The content is from the Utah State University and is edited by the university. Content is easy to navigate and understand because it focuses on students from K-12. Content: The National Teachers Council of Mathematics five content standards are listed vertically in a grid, while the grades for each of the standards are listed across the top of the grid. Navigation based on the content standard and grade level appropriateness is accessible because of this organization. Teachers just need to find the content standard and line it up with the appropriate grade level. Although the site has a version that it offers to schools many of the virtual manipulatives are easy to use as long as one's computer has JAVA capabilities. There are four different language options for the different virtual manipulatives, so it makes it easy to use in bilingual settings (English, Spanish, French, and Chinese). The main reason for this website is to offer teachers with computer technology to teach manipulation of different math areas when the physical manipulatives are not available. Teachers can also use the site to help explain concept clarity of hard to understand math functions. Design: The initial web page offers a grid of math standards and grade levels from K-12. Teachers can click on the appropriate link and it will lead them to more options on different subjects in the content areas. None of the links are broken for the virtual manipulatives. Design of the website is updated often by the USU. NLVM also allows users to select from four different languages.

Kaci Philpot Overview: The purpose of this site is to provide teachers and students with fun, interactive Math manipulatives online, because manipulatives help students to see visual relationships in Math and help to actively engage students. The website has the following standards for math education; numbers and operations, algebra, geometry, measurement, and data analysis & probability. Each standard has four different age groups to choose from: pre-k through 2, 3 through 5, 6 through 8, and 9 through 12. This website is one of the very few educational websites I have found that is free and clear or useless information and clutter. Content Summary: This website content quality is very high; it has an index chart on the homepage with grade levels and math standards. Each box on the chart is linked to a page of full of various virtual Math manipulatives. If you navigate to the credits page you can see who is in charge of creating what, however it does not provide information about or credibility of those individuals. It also does not have revision dates. But the site is well organized and has very rich content. The manipulatives are an excellent way to get students excited about learning math. Total yeses: 19 Total no's: 2 Total N/A: 3 Design Summary: The homepage of this site is very easy to navigate and understand, but it does not have very strong eye appeal at all. But the manipulatives are very useful and all have clear directions if necessary and all internal and external links work properly. It does not appear to have any outdated content, if Mathematics can even be outdated. My favorite link on this website is the link to the Spanish page. This would be very useful for teachers with ESL students; it helps to ease the language barrier. Total yeses: 22 Total no's: 2 Total N/A: 0

Chelsey Lynch 1/31/11 * Overview: This website is for the National Library of Virtual Manipulatives. The intended audience of this site is teachers, and students of all ages. The available resources are a wide array of virtual math manipulatives. This website is extremely useful to teachers because it provides children with a firm grasp on concepts by letting them learn directly through physical objects that enable students to visualize relationships and applications. * Design: This website is attractive and very easy to navigate. The main page of the website contains a large grid system which serves as a menu for the math content area and grade level. All information to contact the sites provider is given, and all the information is current. The instructions for the manipulatives are very easy to follow and the site even provides examples when necessary. This site has adequate graphics, though the music and sounds in games is a little dated and sometimes annoying. * Content: The authors of this site appear to be highly education and experts in this field. The purpose of this site is very clear and the content achieves the intended purpose effectively. This site is extremely interactive, well organized, and easy to navigate. I have personally used this site numerous times and love it. The only things I wish this site contained more of are links to websites that are similar to this or had further information.

Whitney Lindt Purpose: The purpose of this website is for teachers to go to in order to get ideas about what they could do in their classrooms. Not only would this website be useful for just teachers but there are some links off the home page that would be fun for the students as well. Overview: This site would be great for teachers to get different ideas of ways to teach language arts and math to their students. Not only could teachers learn from this website but their students could also learn from this webstie because there are several links between these two subjects that students could play games from and learn at the same time. This website would keep the students engaged with what the teacher is trying to get across because when a teacher can teach with games students can learn more because they are actually involved in the learning process. Content: The content of this website I think does a great job providing links that teach the students in math and language arts. In the language arts section it goes from grammar, to phonics, to reading; meaning that it basically covers everything that students learn as first graders in the class room when it comes to language arts. In the math section of this website it covers mathematical processes, numbers and operations, algebra, geometry and measurement, and data analysis. Some of these math processes might be a little advanced for first graders but it would still be good for them to look at so they are not completely unfamiliar with them as they go higher up in school. Design: What I really like about this website is that it is extremely easy to navigate. It splits up the information into different grade levels and then from there it goes into the different subjects. I think this website was mostly designed for the teachers to use because it is not appealing to the eye if a first grader were to use it. That is the only thing that I do not like about this website is that it is not really that appealing to the eye b
