The Birthday Problem

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Now there are parentheses in these equations? As the lessons continue in this series, equations get progressively more complex. Eighth graders solve equations by applying the distributive property before using inverse operations. 

What does order of operations have to do with solving equations? A video explains solving two-step equations using a do/undo chart. Learners recognize the operations within an equation and use inverse operations to undo those operations. 

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

Can you handle one more method? It just might be your favorite! Building on the skills learned in the previous lessons in the series, scholars now learn the elimination method. The video examines problems of varying difficulty. 

This worksheet manages to provide both fun and serious work solving exponential and logarithmic application problems in engaging story lines and real-life situations. A strong emphasis on science applications and numbers pulled straight...

Turning absolute value inequalities into compound inequalities and graphing them is an algorithmic skill that many young algebrists memorize instead of working to understand. This presentation really emphasizes the how's and why's of...

Using an example from a prior video, this lesson takes the key information and creates an equation to solve for the cost of a museum ticket. The narrator takes the time to talk through all the key steps when solving for x. 

Need to brush up on solving linear inequalities? Review how to solve linear inequalities with a helpful concept video. Three problem videos work through examples of solving linear inequalities.
