Area works with decimals too. Pupils use the interactive to model multiplication of two decimals using an area model. They see how the decomposed components of the factors obtain partial products and then the complete product. Using area...

Make learning visible! Have your mathematicians follow along as you use paper strips to demonstrate the concept of multiplying unit fractions. Then, offer a different way of solving the problem using a number line. Finally, introduce the...

Beans, or legumes as they are sometimes called, are the topic for an integrated multi-subject lesson. Youngsters will read, write, observe, and research everything there is to know about beans. They read a bean story, conduct a bean...

The interactive applet allows learners to explore the relationships between side length, area, and perimeter. Students see how changes in the scale factor influence the ratio of areas and perimeters. [Requires Java.]

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to determine missing angles within rectangles and squares.
