This site is a tutorial that models fractions with number lines or circles through several different options. Applets are divided into categories such as identify fractions, rename fractions, compare fractions, investigate fractions, and much more. Each category contains different options for exploration with flash applets to practice that skill. The "investigate" option offers step-by-step explanations of the different categories and would be very useful to offer students when reviewing skills such as comparing fractions and using order of operations. Some of the slide shows are also available in PDF form along with practice worksheets. Another component of the site allows you to input your own fractions to practice your own examples.

tag(s): decimals (125), fractions (229), percent (81), test prep (95)

#### In the Classroom

Introduce this site on your interactive whiteboard or projector. Have the students open the site and use the whiteboard tools to explore and practice different aspects of fractions. Then have students explore this site independently or in small groups. Use this site on a projector or interactive whiteboard to discuss and informally assess prior knowledge as you start your study of fractions. Create a link to this site on classroom computers, and your classroom website or blog for students to explore.

This site offers many opportunities for math exploration for both teachers and students. Although they have a store and ads on the site, much of the site is free and worth a visit. One especially helpful portion of the site is the link to different types of calculators from basic to graphing to mortgage and loan calculators. Students and parents will find the homework section of the site helpful as it is categorized by different topics, then each topic is further divided into sections. For example, under fractions you will find definitions, reducing, adding and subtracting, multiplying and dividing. In each of those portions there is a section with a first glance (overview), in-depth, examples, and workout. There is also a unit quiz for each section. Another helpful area of the site is the practice section which offers practice in many different math skills such as square root, percent, and integers. The games section offers practice with critical thinking skills through logic puzzles and games such as chess.

tag(s): calculators (39), fractions (229), integers (40), percent (81), test prep (95)

#### In the Classroom

Below the list of information are common properties of the number entered. Some numbers also include links to web pages about that number - for example, enter the number 6 and there is a link to Some Thoughts on Number 6 by John Baez.
