Your algebra students double their money monthly in this task based on a checking account balance. Learners write an equation to model the situation and then use their model to answer contextual questions.

0/0 doesn't equal 0! Begin this lesson by allowing the class to explore the concept of dividing by zero. The introduction allows for discovery and provides meaningful examples of dividing by zero. This understanding leads to solving...

Investigate the application of vector transformations applied to linear systems. Individuals use vectors to transform a linear system translating the solution to the origin. They apply their understanding of vectors, matrices,...

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. 

How well can you launch a ping-pong ball? Small groups design launchers that can launch a ping-pong ball 20 feet into a target. The teams follow the engineering design process as they develop a solution that meets the design...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

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.

Find the perfect amount of water for lemonade. Scholars solve the famous problem of measuring four liters of water using a three-liter container and a five-liter container. An interactive allows users to see each step of the solution.

What do a line and an ellipse have in common? Maybe zero, one, or two points! Learners consider the equation of an ellipse and a line to determine if their graphs have any shared points. They then write a system of equations, including...

Here's a clever switch on the tale of Pandora's Box. Rather than lifting the lid and having problems escape, class members write a problem on a strip of paper and place it in Pandora's Problem Box. A student  then pulls a problem...

Seventh graders create and perform a skit that demonstrates their conflict resolution skills. They begin by examining the process of crafting a performance and review what they have learned about conflict resolution. Next, they...

Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

Scholars complete the Reality Chech handout that identifies their potential salary given a specific profession. Pupils examine the lifestyle options and choose what they wish to have; however, each item costs money and, depending on how...

Zero in on your pupils' understanding of solving quadratic equations. Spend time developing the purpose of the zero product property so that young mathematicians understand why the equations should be set equal to zero and how that...

A simple lesson with a lot of support behind it. Your learners will find out how long it takes Molly to run a mile by choosing their solution method. The activity can be used as a lesson or as an independent assignment. Preface with...

Your learners will get plenty of practice solving quadratic equations in a worksheet using the quadratic formula. An extension to this activity would nicely connect MP5 concepts. Have learners use a graphing program to graph the...

Don't spill the beans ... before the end of the lesson! Learners must predict how long it takes two people working together to fill a glass with beans. A video presents the rate it takes each person independently, and another video...

Do the math before you do something crazy—like filling a pool full of Coca-Cola. A video shows a pool owner filling a large backyard pool with bottles of Coke. Scholars use the dimensions of the pool to determine the number of bottles...

Learners won't consider a practice crossword puzzle on Shakespeare's Julius Caesar proves to be the unkindest cut of all. As they complete the puzzle, high schoolers review key concepts and characters from the play, checking both...

Bring all the factoring together. Pupils view a video presentation that shows how to combine all the factoring techniques from Unit 9 together to factor more complex polynomials. Learners practice with three items within the presentation...

A transformational assessment determines how far pupils are advancing toward mastering complex and matrix standards. The assessment checks the learners' understanding of linear transformations, complex numbers and the complex plane,...

Challenge scholars to show what they know about properties and addition and subtraction formulas for trigonometric functions. The resource provides a mid-unit check on the progress toward mastery of trigonometric concepts. The areas...

Perimeter check! Pairs work on finding the areas of semicircles and quarter circles using a relationship with squares. The problems challenge pupils to find areas of composite figures made from rectangles, semicircles, and quarter circles.

There may be plenty of horror in Joseph Conrad's novel Heart of Darkness, but studying the details of the plot doesn't need to be horrific. High schoolers complete a short crossword puzzle to review the names, events, and...
