Linear, quadratic, and now cubic functions can model real-life patterns. High schoolers create cubic regression equations to model different scenarios. They then use the regression equations to make predictions.

Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Reach for the STARs! Using the resource, scholars review the STAR (Stop, Think, Act, Review) method and discuss how to use it to solve a math equation. Next, small groups collaborate to solve a common problem in the classroom using the...

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Speed up your scholars' understanding of ratios. Class members compare ratios related with speeds presented in different representations. They then use the unit rates to make the comparisons. 

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Students read "The Magic School Bus in the Human Body" and discuss the importance of maintaining a healthy body. They create a hinge and joint paper skeleton, follow the journey of a hamburger through the digestive tract, jump rope and...

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...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Approach the lesson from the right angle. A discussion-based lesson leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The lesson is...

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

Candy is always an effective motivator! A fun math activity uses M&M's and Skittles to explore two-way frequency tables and conditional probability. The candy can serve a dual purpose as manipulatives and experimental data.

Make your class into Pythagorean theorem fanatics in no time. What a great resource to get your sports enthusiasts into the math game! Read the commentary so you can you can strategize how to apply the three math practices.

Examine the relationship between time and geometry. A series of five lessons provides a grade-appropriate problem from elementary through high school. Each problem asks learners to compare the movement of the hands on a clock to an angle...

Take a shot using a lesson on volume! Young learners watch a video showing a trashcan filling with paper balls. The task is to calculate the number of paper balls that will fit in the can. Pupils use volume calculations to make a...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

Try to figure out what happens with shadows as a person moves between two light sources. A formative assessment lesson has individuals work on an assessment task based on similar triangles, then groups them based on their...

Which function models the data best? Pupils work through several activities to model data with a variety of functions. Individuals begin by reviewing the shapes of the functions and finding functions that will fit plotted data points. By...

Did you know the hole in the ozone is seasonal and filled by January every year? The lesson plan uses scientific measurements of the ozone over the South Pole to understand patterns. Scholars learn that the hole grew bigger annually...

Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...
