Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

If the shoe  doesn't fit, design a new one. Discovery Education challenges pupils to put the engineering process in action by designing a shoe. Groups design and build a shoe prototype based upon the client...

The Learning Network has formulated a fill-in the blank worksheet to go along with the New York Times article "Olympic Mascots Inspire Imitations". While the topic is not entirely about physical education, this article could be used for...

Unemployment: The job of the future. The resource, designed for high school scholars, explains unemployment rates, recessions, and job trends that are impacting employment in the United States. Academics explore potential careers of the...

In this computer education matching learning exercise, students draw a line from the task to the type of program that would be best suited to the task. They match 10 tasks to their programs.

Who is Salman Khan? That is the first question learners will answer after reading a New York Times article about the online math and science educator. They'll read the article and respond to eight questions that ask, who, what, when,...

How does your data stack up? A hands-on activity asks pupils to collect a set of data by measuring their right-hand reach. Your classes then analyze their data using a free online software program and make conclusions as to the...

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

Welcome to the code side. The interactive lesson introduces coding in a game format with familiar characters. Young computer experts learn to develop code to control the interaction of the characters in the game. The activity ends with...

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...

Introducing Mr. Robot. As an introduction to robotics, class develop a definition of a robot and make distinctions between real robots and those in science fiction. They also study the basics of programming in Java to...

Look at it go. The resource, the third in a series of five using a Roomba, explains the different types of movements a Roomba makes, then challenges pupils to create computer codes that will cause the Roomba to travel specific paths.

Introduce your classes to sensors and actuators in robots — specifically to the Roomba. Pupils develop programs that make Roomba utilize its different sensors.

Where is my robot? Pupils create programs that utilize the localization services that a Roomba uses to determine its surroundings.

There are places in the US where a road cannot be found for miles! The lesson asks learners to use random longitude and latitude coordinates within the US to collect data. They then determine the sample proportion and confidence interval...

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation....

Young analysts use real (provided) data from a class's test scores to practice using statistical tools. Not only do learners calculate measures of center and spread (including mean, median, deviation, and IQ range), but...

By making the following changes to the roads, we can prevent several accidents. A multiple-day lesson plan prompts pupils to investigate accidents in a small town. Pairs develop a proposal on what to do to help reduce the number of...

Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...

Something for young mathematicians to remember: the sum of any two sides must be greater than the third. Class members investigates the Triangle Inequality Theorem to find the relationship between the sides of a triangle. At the...

Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.

High Schoolers explore the concept of exponential reflections. They use their Ti-Nspire to reflect the natural logarithm function over the line y=x. Learners repeat the process using different exponential functions using a slider.

Explore linear functions! For this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

Young mathematicians practice their reasoning as well as adding and subtracting skills with this worksheet that includes five simple word problems about birthdays. Learners are give pictures of birthday cakes and based on the number of...
