One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Two of the strategies for solving systems of linear equations are represented in this foldable: substitution and elimination. Learners solve three examples of each. 

One solves inequalities just like equations ... well, almost. Pupils watch a video lecture on solving linear inequalities. They practice solving inequalities, check their answers with the video, and continue to practice the concept with...

Your learners will appreciate the complete picture of linear inequalities presented in this lesson plan. Starting simply with definitions and moving all the way to solving linear inequality word problems this activity is simple to...

Your microbiologists explore the graphing of exponential growth functions using bacteria, like e. coli and salmonella, in a well-written, career and technology lesson plan. 

Everything one wanted to know about parabolas in one place. Pupils work 27 problems as a review of the unit on quadratics. Problems range from determining key features of the function and using that information to graph the parabola, to...

Wrap it all up in a box. Pupils review the key concepts from an Algebra 2 polynomial functions unit by working 19 problems. Problems range from using the Remainder Theorem to find remainders and finding factors; sketching graphs by...

The concept of slope gets an approachable, yet theoretical, treatment in a comprehensive algebra activity. The use of functional notation and problem-solving techniques keep the material rigorous, but detailed teaching notes and lots of...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Have you ever wanted to download a great lesson, but you weren't sure if you had enough time? Scholars learn to create a function for this situation to determine when a file will finish downloading. They also learn the difference between...

Your learners will practice many ways of describing data using coordinate algebra in this unit written to address many Common Core State Standards. Simple examples of different ways to organize data are shared and then practice problems...

Third graders demonstrate their estimating and measuring abilities.  In this length measurement instructional activity, 3rd graders produce estimates of how long a handful of French fries will be before physically measuring them....
