Serve up a slice of math for Pi Day! A combination of fun, hands-on lessons and helpful worksheets encourage learners to practice finding the radius, diameter, and circumference of different circles.

What do animated videos have to do with mathematics? Using operations of complex numbers and their representations on the complex plane, high schoolers observe how mathematics could be used to move animations. The lesson plan...

Do you need to graph lines to see the point? A thorough lesson plan provides comprehensive instruction focused on solving systems of equations by graphing. Resources include guided practice worksheet, skill practice worksheet,...

Arithmetic and geometric sequences are linear and geometric patterns. Help pupils understand the relationship and see the connection with an activity that asks them to write the rules and classify the patterns correctly. A sorting...

A new, improved version of the game Battleship? Learners graph linear inequalities on the coordinate plane, then participate in a game where they have to guess coordinate points based on the solution to a system of linear...

Quit repeating yourself ... you can make this simpler! Rather than repeating the same set of code over and over, class members learn to build and call functions in a series of challenges in App Lab. In the end, they combine...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

The topic of trigonometric ratios is often covered with loads of rote memorization baked into the activity. This activity set, however, leans more on using similar triangles and discovery learning to help young geometers develop a deeper...

It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...

A fun, engaging activity is definitely in the cards for your future. Pupils explore a deck of playing cards in the fifth of six parts in the Statistics and Probability series to learn about its suits and the number of each card type....

Flip a coin: heads, use the resource; tails, use the resource. The fourth of six installments of the Statistics & Probability unit looks at coin tosses and probability. The class conducts an experiment and sees that the outcomes of...

Life's not fair, but dice games should be. After playing a two-person game with a pair of dice, scholars investigate the fairness of the game. They consider the number of possible outcomes using the fundamental counting principle and...

Transform your learners into master geometers with an activity that asks them to first complete an assessment task drawing the result after transformation of a given shape in the coordinate plane. They then use cards to...

Class members complete an assessment task by identifying whether statements about triangles and quadrilaterals are always true, sometimes true, or never true. They then participate in a sorting activity with the same objective.

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson plan, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take...

Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

 The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...
