This website allows students and teachers to visually explore fractions and how they relate to mixed numbers, decimals, and percents.  You can set it up by area, region, or set of items.  Once you select a fraction it will then demonstrate to students how that relates to mixed numbers, decimals, and percents.

Teachers can create arrays and visually show how division works.  Using the program students can also work on estimation, factoring, remainders, and fractions that all deal with division.  Factor Pairs and Prime factors can also be shown.  Teachers can use this to show why some numbers are perfect squares and some are perfect triangles.  Watch the video to show how to change and use this number explorer with students.

Show students how to use protractors and rulers in this interactive website.  Teachers can also easily show polygons and quadrilaterals.  Shape color size, and angle are easily changed from one shape to another.  You can use this shapes website to show interior and exterior angles.  Arcs can also be manipulated.

In this game, students will identify a fraction and then shoot the correct bubble that contains that particular fraction.  As kids get better the bubbles get faster and more fractions to choose from.

This is a one-minute video that demonstrates to students that shapes can be evenly split and that each piece is one equal part of the whole shape.

Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models. Adjust numerators and denominators to see how they alter the representations and models. Use the table to keep track of interesting fractions.  If your students have computers, yell out fractions and have them create the fraction you called.
