How do you catch a leprechaun? Let your writers decide with a resource that has them thinking about story elements and writing creatively. Learners plan their writing in two graphic organizers—one with setting, characters, problem, and...

As a continuation of a previous lesson, this activity builds on the concept of calculating the terms of a sequence. Pupils are challenged to determine the smallest starting term to reach a set number by a set number of rounds. Notation...

Class members investigate rectangles on the coordinate plane. They determine the length of line segments in the coordinate plane with the same x-coordinate or same y-coordinate and then solve geometric problems involving perimeter...

Assess the ability of the class to solve percent problems with an assessment that covers a variety of percent problems from basic to multi-step. Pupils make connections between percent problems and proportional thinking to complete...

Graphs, functions, symbols, and more! Use these strategies to model everything from the flow of a river to the number of cars passing a toll booth. Presented differently but solved similarly, learners consider five different scenarios...

An interactive offers five questions that challenge scholars to subtract decimals. A diagram featuring a tree and birdhouse with moveable parts is designed to assist mathematicians in finding solutions. Types of questions include...

Half a foot difference may not mean much, but converting that to an 8% change puts it into perspective for young minds. The lesson discusses the idea of converting information into percents to discover errors made and how much it...

A one-stop resource for exponents, square and cube roots, scientific notation, and volume formulas guides learners through properties of exponents. As they learn to apply these properties to operations with scientific notation,...

Let's see how complicated we can make this simple task. The last activity associated with a 10-part series has groups design and build a Rube Goldberg machine. Teams determine a simple task to accomplish and use the engineering design...

Build tables by understanding their structure. Scholars take a closer look at the structure of ratio tables in the 10th segment in a 29-part series. Individuals realize that the tables can be built using an additive or...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Examine the relationship between ratios and scale. Young math scholars compare ratios of two models. They use the ratios to make a comparison between the two models. Each image uses a different scale, which requires learners to think...

What does it mean to have an innovative mindset? Pupils think outside the box with the first of five lessons from the WE Are Innovators—High School Modules set. Scholars read articles and watch videos about sustainable innovation, such...

Learn the importance of geometry to tailors. Given a shirt sewing pattern, scholars determine the actual size of the shirt. After which they answer questions that require problem solving and extending their understanding of scale.

Your learners will get lots of practice calculating simple and compound interest by the end of this lesson. Simple explanations and examples lead learners through the concepts and steps of calculating simple and compound interest...

When you have to flow, you have to flow. The instructional activity introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has...

The ninth installment of a 21-part module has pupils compare integers and rational numbers in decimal and fraction form. They match stories to number lines and compare values in the stories.

Which graph belongs to which summary statistics? Class members build upon their knowledge of data displays and numerical summaries to connect the two. Pupils make connections between different graphical displays of the same data in...

More than half the world's population eats rice as a daily staple ... imagine if that rice could prevent illness. Scientists genetically engineered rice to include vitamin A for just that purpose. However, room for debate still exists....

Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...

Learners demonstrate their knowledge pictorially, concretely, and abstractly in this unit meant to last three hours over three days. Using hands-on activities, manipulatives,  real-world applications, and problem...

Groups write and evaluate expressions for various phone plans and scenarios to find which is the best deal. They then compare different approaches to writing expressions for the same scenario and discuss the concept of equivalent...

Plant the fruits of trigonometry. Pairs work through the process of finding the best place to plant fruit trees on a piece of property. The scholars must take into consideration the location of the property and the solar zenith angle. To...

Take an alternative route with trigonometry and let learners connect a tweaked version of the pythagorean theorem to the original in terms of triangle sides. The assignment leads participants towards deriving the Pythagorean identity...
