Show your shoppers that knowing how to calculate the percent increase or decrease of an item is a handy tool to know when they are looking for a good sale. Use as a quick three example introduction to the topic. The guided practice...

What happens when you have a recipe and need to up the measurements? Here is a lesson that explains how to use ratios to convert measurements and percents with worked out problems. Also provided are additional resources and practice...

Show learners that their choices can change based on probability. The lesson discusses the idea of theoretical and experimental probability when choosing items or flipping a coin. Use the page with the additional resources...

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...

Get a detailed look at plate tectonics with a 14-slide presentation that highlights the Earth's layers, continental drift, seafloor spreading, the theory of plate tectonics, and boundary types. Each slide provides thorough...

Get an in-depth look into erosion and deposition with a 23-slide presentation that details how gravity, water, waves, wind, and glaciers cause changes to the Earth's surface. Each slide consists of detailed images equipped with labels,...

Go from feet to inches to yards and back again with this notes and worksheet combo resource. Several pages of examples regarding unit conversion of the English system are given, followed by different pages of problems. There is a nice...

What does a graph or equation say about a situation? Lots! The lesson uses the concepts explored in the previous four lessons in the series and applies them to problem solving situations. Learners create an equation from problems posed...

Where did all the variables go? Scholars learn how to interpret an equation when they eliminate all variables during the solving process. They interpret the solution as infinite solutions or no solutions. 

Do males or females buy more iPhones? Using a two-way frequency table can help to answer this question. Pupils learn to create two-way frequency tables and then how to analyze the data within the tables. Learners find frequencies,...

Buoyancy is the fine line between a ship and a submarine. The presentation covers fluid pressure, air pressure, Pascal's Principle, elevation, Archimedes Principle, buoyancy, and Bernoulli's Principle.

Enhance your class's understanding of linear equations by extending their study to parallel and perpendicular lines. Young mathematicians learn the relationship between the slopes of parallel and perpendicular lines. They then use that...

The shortest distance between two points is a straight line. Learners use the Pythagorean Theorem to develop a formula to find that distance. They then find the midpoint using an average formula. 

Convey to your pupils the importance of units, then show how to use dimensional analysis to perform a unit conversion. The math lesson includes detailed worked-out solutions to guide learners in their practice.

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Some data just doesn't follow a straight path. Learners use line graphs to represent data that changes over time. They use the graphs to analyze the data and make conclusions.

There are many different options for graphing data, which can be overwhelming even for experienced mathematcians. This time, the focus is on histograms and Venn diagrams that highlight the frequency of a range of data and overlap of...

Whiskers are not just for cats! Pupils create box-and-whisker plots from given data sets. They analyze the data using the graphs as their guide.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

There are architectural parabolas all around us! A creative lesson analyzes the architecture of a parabolic bridge. Learners must manipulate the bridge to satisfy given criteria and then answer questions about the dimensions of the...

Who wouldn't want to wear four pairs of sunglasses? Each pair of sunglasses reduces the percent of incoming light by one-half. An interactive tutorial helps young mathematicians build a graph that models this scenario. They...

Explore the conversion of numbers to scientific notation and back again. Learners begin with a matching activity to identify equivalent expressions. Then guiding questions test and extend their understanding.
