Upper grade and middle schoolers make predictions, collect data, and interpret the data as it relates to the concept of probability. They work with a partner tossing marshmallows and recording if they land on their side or on their...

A comprehensive lesson that explores and researches Pascal's triangle and relates its properties to the Binomial Theorem through a variety of lessons. Have the class practice expanding polynomials using the theorem. A few other formulas...

A fabulous plan on teaching basic concepts of measurement to young learners. Pupils use nonstandard units to measure length, practice using a ruler and a yardstick, compare the length of two objects, and perform estimations of length....

How many potatoes tall are you? Unearth this rich resource! A reading of John Coy’s Two Old Potatoes begins a cross-curricular exploration of potatoes. Class members read, write, weigh, measure, and experiment with potatoes. Additional...

This resource will knock your "sox" off! It comes with so many worksheets, projects, and other attachments that help you prepare your mathematicians to see positive and negative integers in the real world, including the White Sox stadium...

Tenth graders investigate dilations and explore the dilation transformation before investigating the properties of a dilation using Cabri Jr. Young scholars extend the concept of dilatation to the coordinate plane.

Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...

Your class will use a set scale to convert diameters of planets to the model size, the diagram given to expand on the number of planets drawn as concentric circles, and examine the scale that would be needed to fit the larger...

It's all about location, location, location. Small groups work to find the best spot for a rec center to serve three different communities. Learners construct the inscribed and circumscribed circles of a triangle to find the best place....

A watched printer never finishes—or does it? Engage your classes in a ratio and proportion task that asks them to predict how long it takes to print the numbers one through 88 on 88 sheets of paper. They use video to determine the rate...

Ever feel like you're headed up the down escalator? Don't let your pupils get stuck in that rut! Practice writing equations to solve a problem using an engaging lesson. A video presents information that allows learners to determine how...

Depending on your eating habits, you just may not want to know the answer to the inquiry-based question! The task is to determine the number of sugar packets in one 20-ounce soda. Learners use nutritional information from the sugar and...

A dripping faucet may be enough to drive you crazy, but it also teaches you a little about ratios. Presented with the volume of a sink and the rate the water is dripping, scholars must devise a plant to determine how long it will take...

Challenge your classes to design and market a new product. Collaborative groups use geometry skills to create packaging for their products. Finally, they plan a marketing strategy to present to a marketing specialist.
