Your visual geometry learners will appreciate triangle drawings as they model the triangle sum theorem and algebraically solve to find the missing interior angle in a triangle. Practice problems increase in complexity and vary in their...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Show learners the power of mathematics as they model real-life designs. Pupils graph a periodic function by comparing the degree of rotation to the height of a ferris wheel. 

In this points, lines, planes, and space worksheet, learners solve word problems dealing with points, lines, planes, and space. Students complete 20 individual problems and 20 group problems.

Ever wonder how a butcher creates the different types of ground beef? Young mathematicians explore the methods butchers use to create their desired ground beef quality. Given a combination of two types of meat with varying...

How can baseball and skeet-shooting be modeled mathematically? Sports lovers and young mathematicians learn how to use quadratic equations and systems of equations to model the flight paths of various objects.

Learners explore logic and use Geometer’s Sketchpad and patterns of logic to solve a puzzle.

More than just data, scatter plots are full of information that can be used to answer a variety of questions. This lesson uses a plot with information about bird egg sizes to answer questions about the relationship between length and...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Avoiding lab safety rules will not give you super powers. The lesson plan opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and...

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Small groups use rubber bands to accelerate an Android device along a track of books. They collect the acceleration data and analyze it in order to determine the device's velocity. 

What makes a good best-fit line? In the 10th part of a 16-part module, scholars learn how to analyze trend lines to choose the best fit, and to write equations for best-fit lines to make predictions.

Students find the area of three figure by the traditional formulaic methods. Then they count the number of grid squares to double check. They show an intuitive sense of Pick's Algorithm by counting every two boundary squares as one unit....

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...
