This site contains many visual explanations of Math topics including interactive practice activities. Each explanation begins with a definition of the topic (such as adding or subtracting fractions), then moves on to practicing the skill with the interactive pieces. Practice activities at the end of each topic are very visually appealing and will appeal to most students. One of the most useful portions of the site is the glossary which contains definitions of many Math terms along with examples of the terms in use.

tag(s): charts and graphs (198), fractions (229), integers (40), puzzles (203), statistics (128)

#### In the Classroom

This site would be useful for students to practice skills already learned; however, the explanations are not in-depth enough for beginning to learn concepts. Create a link on classroom computers or in the computer lab to use as practice. Use the glossary as a resource on your interactive whiteboard or projector when definitions are needed for math terms. Provide a link on your class website or blog to the glossary for students to access at home. Display the site on your interactive whiteboard, choose a subject such as adding/subtracting fractions, then click the link titled "topic" and choose the final item in the sequence - in this instance it is an activity called The Small Flood. These activities are perfect for whole-class practice in each subject.

Use this as a springboard to classroom discussions on problem solving equations. There are several videos on the site with this topic, so a new video can be shown each day as examples of different problem solving methods. Use the student examples in your classroom to demonstrate how students can explain different math topics, then create your own explanatory video or audio presentations. Have students create podcasts using a site such as PodOmatic (reviewed here). Or challenge students to create a video and share using a site such as SchoolTube (reviewed here). Post student work to your classroom website or blog for students to use at home for review.

This applet provides great opportunities to explore experimental and theoretical probabilities by changing the area of the colored regions of the circle. When a section is added it reduces the other sections by an equal amount in order to add the new sector. When this occurs, the probability that that particular color will be landed on will change. The number of sections of the circle can be changed from 1 to 12, as each spin is made, the color is recorded along with the percentage of time each color has appeared.

Be sure to visit the learner section of the site which contains a nice description of probability and how it is used in the real world. The instructor section also has a lot of valuable information including links to standards and textbooks, classroom information, and related resources. In addition, there is a link to a printable sheet of exploration questions to be used with the site.

tag(s): probability (141), statistics (128)

#### In the Classroom

Introduce this site on your interactive whiteboard or projector. Then have students explore this site independently or in small groups to complete the exploration questions. Create a link on classroom or lab computers for students to explore the site independently. Create a link on your classroom website or blog for students to explore the site at home.
