Using Electronic Manipulatives in Multiplication

Take some intellectual fun and apply it to the concept of multiplying expressions together. A guide models how to break two numbers into an area model to multiply together in pieces similar to FOILing. The rest of the puzzles consist of...

Does complex number multiplication have the class spinning? Here's a resource that helps pupils explore and discover the geometric effect of multiplying complex numbers. In the 14th installment in the 32-part unit groups look at the unit...

To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is taken to discuss...

The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....

Young mathematicians who haven't thought about the mechanics of multiplication since elementary school can find scalar multiplication of matrices intimidating. Enter this short presentation, breaking down the scalar multiplication...

Where many multiplying binomial lessons introduce the tool of FOIL and move on, this video presentation really delves into the how's and why's of the distributive property. Careful treatment of distribution and explicitly written out...

Introduce the class to simplifying algebraic expression using multiplication and division. Showing the connection of the rules for exponents between numerical expressions and algebraic expressions, the video works several examples of...

The class explores a real-world application in which the data represents rental prices of beach condos. They problem solve by multiplying matrices to determine the cost of each property in each season. Several scenarios are presented in...

Visualize matrix multiplication on the coordinate plane. Pupils use the interactive to create a matrix multiplication problem using vectors. The scholars see the resulting product of the matrices as a vector.
