A thorough and professional appearance characterizes a lesson on linear equations. Maturing mathematicians are taught to identify and exemplify linear equations with a single variable. They also classify equations according to the number...

How much can you tell about a circle from its equation? This detailed lesson plan focuses on connecting equations and graphs of circles. Learners use equations to identify x- and y-intercepts, centers, and radii of circles. They also...

How to use the relationship between multiplication and division to solve math word problems is the focus of the lesson presented here. In it, fourth graders work in groups to solve problems posed by the teacher. Then, each group is given...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

Here are the complete set of the math practice standards and the Common Core standards for first grade. They cover operations & algebraic thinking, operations in base 10, measurement and data, and geometry. Illustrated nicely with...

A must-have resource for classes that engage in debate, this packet contains 20 detailed plans for debate games and activities. Everything from how to select evidence to support a position, to structuring a debate on which candy bar is...

To raise awareness and understanding of modern-day slavery, class groups research the various forms of slavery, including human trafficking, read and reflect on case studies, and design a plan of action for their community.

We take a steady shower stream and clean drinking water for granted, but in many countries around the world, the lack of water or a clean water supply is responsible for higher sickness and death rates. Taking a closer look at the water...

The properties of exponents are all linked together and it is your mathematicians' job to discover and apply those rules. The comprehensive lesson begins with a pre-assessment task to check for prior knowledge and then goes into a...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

Young scientists observe deforestation from satellite photos and discuss the importance of forests to the global environment. They then simulate a plot of forest when farmers move into the area over the course of seven years. Finally,...

Space diving refers to the act of jumping from outer space and falling through Earth's atmosphere before parachuting to land. Scholars learn about this extreme activity and study the layers of the atmosphere they must conquer in the...

The carbon cycle is natural and has happened for millions of years, so can humans change it? Young scientists play the role of carbon as they travel through the carbon cycle. They complete two rounds, once before the industrial...

Many people think they can't observe plate tectonics, but thanks to GPS, we know that Australia moves at a rate of 2.7 inches per year, North America at 1 inches per year, and the Pacific plate at more than 3 inches per year! Scholars...

Each of the Earth's spheres interacts with the other spheres in predictable ways. Young scientists explore these interactions through a hands-on activity, graphing, and watching a video. They summarize their knowledge in a video or...

We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...
