Using Electronic Manipulatives in Multiplication

Zero in on your pupils' understanding of solving quadratic equations. Spend time developing the purpose of the zero product property so that young mathematicians understand why the equations should be set equal to zero and how that...

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...

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...

The last step of solving a quadratic factoring problem is often the stumbling block for algebra learners. Setting each factor equal to zero and solving the mini-equations isn't an intuitive process to learners new to the zero product...

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.

An interactive shows graphically the distribution of a monomial across all the terms in a polynomial multiplication problem. Pupils relate the specific example to a more general problem then make conclusions to develop a pattern for the...
