Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

How is religious freedom connected to the conflict between China and Tibet? After reading an online passage of background information, your learners will divide into groups and both read and view an interview with the Dalai Lama. They...

Resistance is not futile ... it is voltage divided by current. Scholars apply their knowledge to a series of ranking puzzles. First, they consider wires of varying lengths and then wires of varying cross-sectional areas. Finally, they...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

How can everyone in the world have access to clean drinking water? Throughout the lesson, learners read about and listen to how water is filtered, what the filtration process removes, and  the best ways to filter. They explore the...

Do you ever give your class the "teacher look"? Without saying a word, they become silent and engaged (hopefully). How do they know what you're thinking? Explore the concept of nonverbal communication and how it relates to our...

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Elementary schoolers who are learning about filtration and mixtures could use this worksheet to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly filtering...

Challenge your class to use their understanding of the engineering design process to design and build a small-scale, off-road prototype for an assistive technology device. Teams select materials to build their scale models, and, using...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Building an accelerometer app for your Android device. Groups develop an app that uses the accelerometer on an Android device. The purpose of the activity is to reinforce the programming design. The post activity assessment challenges...

Solve simultaneous linear equations, otherwise known as systems of linear equations. Pupils practice solving systems of linear equations by graphing, substitution, and elimination. The workbook provides a class activity and homework...

Have your class use the engineering design process to program a vacuum robot. Using computer engineering concepts, teams program an automatic floor cleaner to traverse designated patterns. 

See how a marshmallow can hold up a bridge load. Teams take a closer look at the design of bridge piers. They determine the types of loads that might affect a bridge, and, using that information, they calculate the needed cross-sectional...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

Up it goes! Groups must design and build a windmill able to lift a weight. The packet includes discussion points to use prior to the build that cover topics such as variables, fairness, and the design process.

Explore methods for solving linear systems with your classes and introduce learners to using matrices as a viable method. Scholars are able to recognize situations where matrices are the efficient method of solving. Application...

Investigate the world of unknown quantities with a creative set of five lessons that provides problem situations for varying grade levels. Each problem presents a scenario of fruit with different weights and a balance scale. Using the...

Young environmentally conscious mathematicians solve a variety of problems related to the central theme of uncovering illegal logging activities. They determine a base camp based on given constraints, investigate logging activities and...

Sixteen number families test young mathematicians' knowledge of the commutative and associative property of addition. Pupils list four problems—two addition and two subtraction—related to a given set of three numbers.

Eighth graders use a model to write and solve a story problem. They design a PowerPoint presentation outlining the steps to solve the problem. Students construct a diorama of a scene in the story problem.
