Creating Linear Equations in One Variable
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....

Linear & Exponential Functions
Positioned inside the framework of linear and exponential functions, this lesson is more of an investigation into the effects of changing variables and constants inside an expression. The author takes familiar formulas, those for...

Creating and Graphing Exponential Equations
Frequently found in biology and economic application problems, exponential equations show up as stars in this introductory presentation. Taking no background or knowledge of exponentials for granted, the slides walk learners...

Volume (Lesson 1)
Add to your teaching tools an interactive presentation in that it's meant to be used in tandem with manipulative cubes. Each slide asks pupils to create a shape that uses a certain number of unit cubes. They are encouraged to make as...

Creating and Graphing Linear Equations in Two Variables
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...

Odd or Even
A great way to show the difference between odd and even numbers is by using blocks. The graphics in this PowerPoint do a great job at showing the two groups of numbers. Tip: After viewing this presentation, have students experiment with...

Tens and Ones
Here is a decent presentation for very young mathematicians on place value. The tens and ones column are covered. This PowerPoint would be useful as a starter. After viewing this, I would break out the manipulatives and let kids use...
