The children have been practicing decomposing areas and now digits in order to understand and use the distributive property.

Children need to move from the manipulative expressions of the distributive property into the mathematical equations eventually. This lesson is the first step in leading them to that goal.

This lesson contains a video lesson [9:28] and various exercises about the area of rectangles, common units of area, two-part rectangles and the distributive property, and shapes composed of rectangular areas.

Practicing math problems is a great way to study for a math test!

College professor Dan Bach presents a review of algebra concepts, including factoring, quadratic equations, and graphing parabolas. The examples are detailed, but easy to follow. This is a good site for reviewing before tests and quizzes.

After finishing this tutorial, you'll be well versed in various properties of real numbers: identity and inverse properties, commutative and associative properties, and distributive properties. You'll also know about the various symbols...

Overview of the four basic number properties with examples.

Visualize solutions to multi-digit division problems by modeling them with virtual manipulatives. This interactive exercise focuses on calculating quotients by working with area models and visualizing the distributive property of division.
