The probability of learning from this lesson is high! Learners calculate probabilities as numbers and as decimals. They see how to use a complement to find a probability and even try a simple geometric probability problem.

Practice using linear models to answer a question of interest. The 12th installment of a 16-part module combines many of the skills from previous lessons. It has scholars draw scatter plots and trend lines, develop linear models, and...

Food takes a trip to the table. Class members choose a meal from a menu and calculate the total cost of the meal including tax and tip. Using a food origin card, pupils determine how far each of the ingredients of a meal traveled to end...

How many things does one transformation tell you? Learners compare and contrast the graphs of different parent functions with the same transformation. Using a rational and absolute value function, pupils identify key features of their...

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Use a progressive tally sheet to keep track of a class tournament. With seven rounds of two-table play, a place for noting points, and directions for use, the resource is a fun way for kids to compete in or out of class.

Who doesn't like building blocks? In the task, pupils use a given diagram of a tower to determine the number of needed blocks. Using this information, pupils then develop a function rule relating the height of the tower to the number of...

Around and around you'll go! Learners analyze the periodic nature of a Ferris wheel. Using a trigonometric function, they make predictions about the location of a specific car at the end of the ride and its total trips around the circle.

Balloons aren't just for parties! An inquiry-based lesson explores the idea of using balloons for space exploration. Learners become engineers as they attempt to control the ascent and descent of a helium balloon using different masses.

Challenge scholars to plan a vacation with a $5,000 budget. Learners review costs of transportation, meals, and entertainment while considering the number of people and destination. Worksheets provide information and...

In this online math worksheet, students practice using their calculator to perform trigonomic functions. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific...

Learners are designing a stunning new water feature for an aquarium, but they soon discover that more than just a pretty home for their fishy friends is required.  From calculating the volume of a composite shape through the...

Find the age of a fictional sample of rocks using a genuine approach. A well-designed lesson asks young mathematicians to use exponential modeling to analyze half-life. As a project-based learning activity, scholars communicate...

Middle school energy experts read about the relationship between energy use and cost-efficiency. Then they work through a couple of scenarios to determine which approach is more cost-effective.

Are you nuts? An engaging experiment burns nuts to find their kilocalories. Young chemists analyze at least two different types of nuts with their experimental results versus what is on the package. The resource offers a great lab...

Forgive me, I regress. Building upon previous modeling activities, the class examines models using the regression function on a graphing calculator. They use the modeling process to interpret the context and to make predictions...

Performing calculations is for more than just mathematicians — it's an important science skill, too. Demonstrate the pH calculations using the slide show resource. The final resource of a seven-part unit introduces young scientists to...

Going around in circles trying to find a resource on sectors of circles? Here is an activity where pupils first complete an assessment task to determine the areas and perimeters of sectors of circles. They then participate in an...

You can lower your ecological footprint by recycling! Lesson four in this series of five has individuals, through the use of a computer, calculate their ecological footprints. Through discussions and analysis they determine how many...

Students collect height versus time data of a bouncing ball using the CBR 2™ data collection device. Using a quadratic equation they graph scatter plots, graph and interpret a quadratic function, apply the vertex form of a quadratic...

The humble soda can gets the geometric treatment in an activity that links math and science calculations. After a few basic assumptions are made and discussed, surface area calculations combine with density information to develop an...

How does your lifestyle measure up in terms of your ecological footprint? Young ecologists examine their impact on the planet using an insightful online calculator. A short quiz asks users to rank the size of their homes, their energy...

Given four sets of data, zombie-loving mathematicians find the mode, range, mean, and median for each set. The sheet is more challenging if calculators are not used; but the data set with large numbers may require a calculator.

Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...
