The LCM will be your new BFF. Learners review least common multiple and least common denominator applications, mostly on fractions, from middle school. Scholars then see how the LCM can be applied to various types of problems from...

In statistics, probability rules—literally! Learners use their previous knowledge and explore a set of rules for conditional probability, independent probability, and complements. Given different scenarios, they must determine what type...

What is a community? Find out with a activity that sheds light onto the different types of communities—school, local, and global. Scholars read informational text detailing the life of a young girl from Cape Verde and take part in a...

There are many equations Algebra I students are not ready to solve. Graphing to solve gives them a strategy to use when they are unsure of an algebraic approach to solve the problem. The lesson exposes learners to a wide variety of...

Help pupils to determine whether using square roots is the method of choice when solving quadratic equations by presenting a instructional activity that begins with a dropped object example and asks for a solution. This introduction...

Introducing inverse functions! The 20th installment of a 35-part lesson encourages scholars to learn the definition of inverse functions and how to find them. The lesson considers all types of functions, not just exponential and...

If someone yelled for eight years and eight months, they could produce enough energy to heat one cup of coffee. A lesson plan on energy encourages scholars to research 10 different energy sources in groups before playing a game. Twenty...

Not all linear functions are linear transformations, only those that go through the origin. The third lesson in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at examples...

Need a real scenario to compare functions? This lesson has it all! Through application, individuals model using different types of functions. They analyze each in terms of the context using the key features of the graphs. 

What does it cost to keep the lights on? Through a hands-on activity, class members use a watt meter and determine the amount of energy different types of light bulbs use. The class then determines the financial and environmental...

Mathematics set notation can be represented through a computer program loop. Making the connection to a computer program loop helps pupils see the process that set notation describes. The activity allows for different types domain and...

The matrix — it's not just a movie. The instructional activity introduces the concept of 2 x 2 matrix multiplication as a way to represent linear transformations. Class members determine when a linear transformation represented as...

Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...
