- Cuisenaire Rods
These brightly colored, perfectly proportioned blocks can be used to teach a variety of math concepts including basic operations, fractions, decimals, percentages, algebraic reasoning, and geometry.
- Fractions activities
As part of the NCTM's Illuminations site, this 4-part website provides and introduction and video-based activities on fractions. This particular activity is geared for grades 3-5 and promotes conceptual thinking regarding fractions.
- Fraction Bars
A very versatile model that is similar to the use of Cuisenaire rods except that bars are segmented. Students can create bars of any size from 1 to 10 in any color and place them anywhere on the screen. Multiple bars are easily made. There are no numbers or evaluation of what is being done.
- Fraction Concepts
From the eNLVM, this site takes the user through several lessons including what fractions describe, fractions in real life, and representing and relating fractions.
- Fraction Pointer
A good applet for connecting an area model with the number line. After creating area models for two fractions, the user must then create a new fraction between the first two. Similar to the Illuminations applet, Equivalent Fractions.
Students use models to find common denominators in order to compare two fractions and then locate both fractions on the number line and a new fraction between the first two.
A tool for exploring equivalent fractions. Proper fractions are presented randomly in either square or circular formats. Students can slice the model in as many parts as they wish to see which slicings create equivalent fractions. Students enter an equivalent fraction and then click a button to check their response.
Users are given a fraction and a model that can be subdivided into as many sections as desired. By clicking on sections the fraction model is shaded to match the given fraction. Two even simpler versions are also available.
- Fraction Track
Players position fractions on number lines with different denominators. Fractions can be split into parts. A challenging game involving equivalent-fraction concepts.
The FunBrain website contains numerous games on finding equivalent fractions.
- Math Forum
Part of the Math Forum web page that provides lessons and activities as well as answers about fractions and decimals.
A website by ProTeacher that provides lesson plans on fractions and decimals.
- Teaching Elementary Mathematics Fractions P - 8
This link leads to a "Web Workshop" titled "Teaching Elementary Mathematics Fractions P - 8." Within the workshop are many links for teachers to click on, from journal articles relating to fractions to activities to use with students.
- Who Wants Pizza? A Fun Way to Learn Fractions
Not an applet but a series of interactive, albeit straightforward, lessons on fraction s from the meaning of fractions through multiplication.
