Fall back and slow down. The fourth lesson in a six-part series on air traffic control leads the class to find the difference in distance traveled based upon the difference in speed. Pupils work through a problem related to walking...

Expand on learners' understanding of quadratic-linear systems. Building on the graphic understanding developed in the previous lesson, pupils learn algebraic methods of solving the systems. 

Collaborative groups utilize their knowledge of parent functions and transformations to determine the equations associated with graphs. The graph is then related to the scenario it represents. 

The language and features of functions get careful treatment in a complex but doable lesson. Learners get a lot of practice really figuring out what a graph means in context, and also identifying key features of graphs. Key ideas...

Introducing inverse functions! The 20th installment of a 35-part lesson encourages scholars to learn the definition of inverse functions and how to find them. The lesson considers all types of functions, not just exponential and...

Build an understanding of rational numbers and their counterpart irrational numbers. Lead learners through an explanation of rational numbers and the ways they can be expressed. Then introduce them to irrational numbers and make...

How likely is it to draw a blue marble? Pupils find the likelihood of events and connect that to the probability of the event. They find the probabilities of simple events and show their probabilities on a scale.

Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Follow six steps to implement this series of metric worksheets. Here, mathematicians exhibit their knowledge of problem solving, while converting units of measurement and label their answers with the applicable unit name.

Why do all sizes of pictures not show the same thing? Class members analyze aspect ratios of various sizes of photos. They determine which sizes have equivalent ratios and figure out why some pictures need to be cropped to fit...

To examine mathematical functions in a modeling situation pupils combine quadratic and step functions to represent a presented scenario. They both graph and write a function to represent data shown in a table. 

Reverse the wrapping to get to the gift. Using the idea of unwrapping a gift, the activity 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...

All work and no play makes for a boring classroom! Bring back memories by analyzing the patterns of a tether ball. Given the dimensions of the ball, pole, and rope, young scholars must determine how many times the ball will wrap around...

Learn to use mathematics to your advantage! Using linear modeling, scholars predict the date and time the Apple App Store reaches 25 billion downloads. Considering the prize for the 25 billionth download was a $10,000 gift card, modeling...

This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives...

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

After identifying which of the given coordinate points fall on the graph of a line and which fall on the graph of a parabola, pupils write equations for each function.

Students calculate the threshold value for the number of susceptible people needed to create an epidemic. They examine a real life flu epidemic and use the SIR model to solve the problems. Students discover they can use mathematics to...

Second graders encounter the need to assess the code in English for tens is that the word ends in "-ty." They explore the meaning of two or three digit whole numbers to realize that the meaning of words like sixty can be decoded by...

Third graders create their own chenille stems to use during this and future lessons. As a class, they discuss the difference between equal and non-equal groups. In groups, they brainstorm a list of items that come in groups of two,...

Students construct number sentences. In this computation lesson, students participate in a game using four numbers to make the number 24.

Sixth graders listen to Demi's, On Grain of Rice: A Mathematical Folktale. They use the problem solving strategy of finding a pattern to determine the number of rice Rani will receive after 30 days. They create a spreadsheet which...

Second graders count by 2's to get to 100. For this counting lesson plan, 2nd graders use the program Kid Pix to create stamps two at a time until they get to 100.
