In this algebra worksheet, students calculate the maximum and minimum of a shaded region. They identify the boundaries and their vertices's. There are 2 problems.

Students investigate the area of squares and circles. In this geometry lesson, students calculate the area and probability of simple events. They work on a laptop using Safari.

Perform operations to add, subtract, multiply and divide matrices. Then solve problems with vectors using matrices. A three day lesson: Matrix Madness, Mystical Matrices, and Decode the Encode. The last lesson has prizes that the class...

Focusing on this algebra instructional activity, learners relate quadratic equations in factored form to their solutions and their graph from a number of different aspects. In some problems, one starts with the original equation and...

Young mathematicians study the relationship between skip counting and multiplication. They build on skip counting skills and examine arrays while studying multiplication. Resources are provided.

Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...

Using Google SketchUp, learners draw a model of their bedroom. They begin by measuring the dimensions of their bedroom, inputting this information into the software program, and calculating perimeter and area. This is an interesting and...

Fifth graders take a close look at the types of ships that travel through the Hudson River Valley on the Hudson River. They utilize worksheets embedded in the plan in order to answer questions about exactly what is being shipped, and how...

High schoolers explore the different fields of bioengineering. They will create and interpret graphs from cancel cells data. They then calculate the amount of drugs found in blood and eliminated by the body over time.

Traffic is a very real concern for any Urban dweller. After watching a video showing various traffic issues and solutions, learners group up to discuss and develop innovative traffic solutions of their own. They explore vocabulary and...

Auntie Litter is here to educate young scholars about water pollution and environmental stewardship! Although the 15-minute video clip is cheesy, it's an engaging look at the water cycle and conservation. Learners start by illustrating...

When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

Mathematicians need to know that not all numbers are rational. We approximate irrational number with rational numbers. That is why a calculator may be misleading. This task give learners an opportunity to see how rounding a number and...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson plan series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

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...

After an introductory activity to demonstrate the theory of a limit, additional activities approach a limit from graphical, numerical, and algebraic methods. The activity looks at the multiple ways of understanding and evaluating a...

Here's an exciting and innovative activity that's sure to get your charges fired up! In it, they use engineering design principles to construct and test a fully solar powered car. One caveat: the kits that each group needs to make their...

...Then the water heater exploded like a bomb. Using a video of an exploding water heater, the resource presents the definitions of energy, potential energy, and kinetic energy to be used in later lessons of the unit.

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water.
