Using Electronic Manipulatives in Multiplication

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...

Let me show you how easy matrix multiplication is. The lesson plan provides guidance to teachers for direct instruction of matrix multiplication. Given the size of two matrices, scholars determine whether they can multiply the two....

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....

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...

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...

Take a different view at matrix multiplication. Based on vector transformations, the video presents matrix multiplication as the result of the composition of multiple linear transformations. The presentation explains the numerical...

Connect the commutative property to commuting. The quick video shows how to use the commutative property to write sums and products in a different way. It provides examples to show that the property only works for addition and...

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...
