Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.

Look at climate change around the world using graphical representations and a hands-on learning simulation specified to particular cities around the world. Using an interactive website, young scientists follow the provided...

You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

Challenge the class to prove that the dilation properties always hold. The instructional activity develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...

The original drawing is eight units — how big is the scale drawing? Classmates determine the scale percent between a scale drawing and an object to calculate the length of a portion of the object. They use the percent equation to find...

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

Lead your class on an exciting journey through the world of math as they review geometry facts and solve for unknown angles. They learn how to use auxiliary lines and congruent angles to correctly complete each practice problem...

Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Lead your class on a search for precious bones. Using a presentation, the class investigates the golden ratio in art and nature. Groups of pupils measure specific bones and find the average ratio for the class. To further cement the...

Keep your mind and body fit with a fun activity about the five food groups. After going over the functions of fruit, vegetables, grains, meats and beans, and dairy, as well as oils and fats, learners participate in a bean bag toss...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

Wrap up an engineering lesson plan with a worthwhile project. An engineering design task challenges groups to develop a package for a pharmaceutical company given constraints on the volume. Learners then create a presentation to...

Both The Ugly Duckling and The Tortoise and the Hare are great additions to an elementary language arts lesson. Young readers focus on the literary elements of each story, including characters and plot development, and apply...

Second graders observe and demonstrate how to measure different objects. They listen to the book "Corduroy," and measure different aspects of a teddy bear, discuss how to measure using a variety of units of measurement, and complete a...

Middle schoolers examine the statistics of March Madness, the college basketball tournament. They watch videotaped basketball games to collect data for further analysis using Word and Excel. They analyze the data in a variety of...

Students explore a variety of math concepts. In this integrating technology lesson, students visit online webtools such as Max's Math Adventure, I Know That Math, Hands on Banking, and more.  A description of each website is provided.

A fun (and delicious!) instructional activity teaches measurement to your third graders. They work in small groups to first predict, then to measure the weight, circumference, and number of seeds found in a watermelon. Everyone gets to...

Students explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Students collaborate in graphing additional functions.

Middle schoolers identify how many smaller units can be found in a later unit. In this geometry instructional activity, students calculate the volume and the transfer amount to a smaller unit. They solve real life problems using the...
