Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

In this air pollution worksheet, learners simulate acid rain falling on soil and determine the pH of the soil after spraying it with an acidic solution. They measure the pH of water sprayed with an acidic solution to represent the...

It's gettin' hot in here! An investigative activity has learners measure the heat of reaction in a virtual setting. After exploring the reaction, they attempt to create a solution at an exact temperature.

Discover how to solve systems of inequalities by graphing. An informative video shows pupils how to determine the solution set after graphing each inequality of a system. To finish, a worksheet gives them a chance to practice this skill.

Students write a story. In this writing lesson plan, students are given a series of prompts to promote them in writing a story. The prompts include writing a free write, writing about characters, writing about a setting, writing about...

For this buffer solution worksheet, high schoolers experiment with the addition of different solutions to a buffer solution and observe the changes in pH using a pH probe. Students describe the differences between adding pure water and...

Students watch demonstrations of paper folded designs that do and do not fly and discuss their observations. They identify problems that they, the Wright Brothers, or NASA scientists face when designing an aircraft, and identify...

In this trigonometric equations worksheet, 11th graders solve 10 different problems that include trigonometric functions. First, they order the equation in terms of one equation and one angle. Then, students write the equation as one...

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...

Learners solve complex radical equations. Solutions vary from one, two, and none, allowing pupils to gain experience solving a variety of problems.

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

Sixth graders practice six steps to effective problem solving. Working with the school counselor, class members are presented with a scenario that requires them to make a decision. Individuals then write a reflection in which they...

Create tables of solutions of linear equations. A lesson has pupils determine solutions for two-variable equations using tables. The class members graph the points on a coordinate graph. 

Systematically combine shapes to arrive at one solution. The resource models a system of linear equations using colored shapes. Pupils follow rules to combine circles and squares to add the two equations together, resulting in one...

Systems of parallel lines have no solution. Pupils work examples to discover that lines with the same slope and different y-intercepts are parallel. The 27th segment of 33 uses this discovery to develop a proof, and the class determines...

Much has been made of the differences between Martin Luther King, Jr. and Malcolm X. But was there any common ground between them? Class members reconsider what they think they know about these two civil rights leaders with...

Middle schoolers apply all they have learned in the Problem Solving module by participating in a contest to see which group can build the tallest tower using only sheets of paper and masking tape.

Learn a different way to determine variability. An informative lesson provides directions on how to calculate the mean absolute deviation of a data set. Pupils use examples to learn the process and then practice finding the mean absolute...

Planes, trains, and automobiles ... the abundance of today's transportation options comes at a hefty price. Using the fifth and final lesson plan from the WE Are Innovators—High School Modules set, pupils explore how modern...

The topics covered in these multiple choice questions are about atomic structure and bonding, state configurations, pressure and solution concentration, and energy graphs. This is a midterm review which could be used with the whole...

Students measure salt content in water. They determine salt content of four samples using a hydrometer.

Students discuss their goals and the steps needed to achieve their goals. They list the internal and external forces that may help or hinder their goals. Students prioritize the forces that hinder and/or help them to achieve their goals.

In this systems of equations activity, 9th graders solve and graph 9 different problems that apply the systems of equations. First, they solve each system of equations by using the graphing method. Then, students write the solution for...

Learners participate in a lesson that focuses on the skill of setting a goal. They practice the setting of a specific goal that can be measured and achievable given the right resources. Students generate a list of goals while going...
