Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to...

Explore politics by analyzing the voting process. Pupils discuss the purpose of casting votes in an election, then examine graphs based on the data from a previously held election's turnout. The lesson concludes as they answer study...

Here are a set of graphing lessons that have a real-world business focus.  Math skills include creating a scatter plot or line graph, fitting a line to a scatter plot, and making predictions. These lessons are aimed at an algebra 1...

Investigate the effect of false positives on probability calculation with an activity that asks scholars to collect simulated data generated by a calculator. To finish, participants analyze the probability of certain outcomes which lead...

Almost every teen wants a car, but can they really afford one? The lesson walks pupils through how to identify a budget, find all of the costs associated with car ownership, and determine if they should buy the car or keep looking.

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

Students complete different activities involving pedometers such as writing a creative story, calculating step averages, researching pedometers, calculating calories, and much more. 

Conditional probability can be a confusing concept. A straightforward lesson provides reasonable examples of conditional probability, and models the most effective ways to reinforce the more complex parts of the lesson.

Reverse the wrapping to get to the gift. Using the idea of unwrapping a gift, the lesson plan introduces the concept of inverses. Pupils first determine the order needed to evaluate a function at a point, then use the reverse to find the...

Just how confident can we be with statistics calculated from a sample? Learners take this into account as they look at data from a sample of petroleum engineer salaries. They analyze the effect sample size has on a margin of error and...

What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...

These aren't models made of clay. Young mathematicians model given population data using exponential functions. They consider different models and choose the best one.

Create a technical report explaining the components of a medical plan through a function. The project-based learning activity gives a medical insurance scenario that young mathematicians model using piecewise functions. Their analyses...

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...

Students define the parts of a database, search strategies to locate information electronically, create/modify databases, etc. and enter data into a prepared spreadsheet to perform calculations.

Students engage in an activity which demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding...

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

Students experiment with an Excel spreadsheet model that demonstrates the effects of interest on payments. They calculate actual costs, interest paid, and time necessary to pay off credit purchases and draw conclusions about the...

Investigate perimeter and area of polygons! In this measurement lesson, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.

A bouncing ball serves as more than entertainment when learning to apply quadratic functions to real-world events. This is the second of a two-part lesson, which can also be accessed from the website. The instructions say to measure the...

Prealgebrarians use colored chips, stickers, and pencils to explore the world of integers. They discover absolute value, compare positive and negative integers, and apply operations to them. A detailed procedure for the three-part...

Here is an exciting exploration of a fascinating topic for your emerging ecologists: bird migration! They begin by visiting the US Fish & Wildlife Service website to discover which Arctic birds come to their areas. They are assigned...

Teach your class how to use descriptive statistics through a hands-on data collection activity. Pupils collect their own data, calculate test statistics, and interpret the results in context. They compare male and female results, looking...

Lead a discussion on the similarities between the properties of area and the properties of volume. Using upper and lower approximations, pupils arrive at the formula for the volume of a general cylinder.
