Learning about proportions through measuring and mapping distances is the focus of this real-world math lesson that doubles as an activity. Mathematicians complete a course designed to measure and map locations in order to put the...

Students solve the mystery of dead Mr. Potato Head using physics and algebra. They discuss Newton's Law of cooling as it applies to the mystery scenario involving a cooling baked potato as the "victim". They manipulate algebraic...

Fifth graders read and write equations. In this equation writing lesson, 5th graders use real life scenarios to write equations. Students use manipulatives, draw pictures and make tables to understand how to write equations. Students...

Young scholars understand the parts of the terrarium and why they are important in establishing an ecosystem. In this ecosystem lesson, students recall background information on aquariums, terrariums and the water cycle. Young scholars...

Young scholars explore the value of money. In this money lesson, students investigating combining amounts of money and making change. Young scholars count sets of money and make fair trades. Resources are provided.

Fifth graders examine patterns and relate to equations to solve math problems.  In this patterns lesson plan, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.

Students discover the Sieve of Erathosthenes. They explore a method to find all the prime numbers in a group of numbers. Using models, students practice divisibility rules while examining the difference between prime and composite numbers.

Students recognize how numbers are used in number stories.  In this Rooster's Off To See the World lesson, students participate in the story. Students complete a number activity and work on the computer to illustrate a number...

Eighth graders develop online writing relationships with students from another area in their state. They write weekly regarding assigned topics, including researching information about the area in which they live.

Students plan a voyage as the captain of a tall ship in the early days of exploration and merchant trading. They choose 2 ships and 3 voyages for a total of 6 possibilities. They calculate the number of days and distance of their...

Young scholars explain how to solve an algebraic word problem using correct grammar and punctuation.  In this math and writing lesson, students are given a word problem and must write down  directions to solve it. 

Explore rigid motion transformations using transparency paper. Learners examine a series of figures and describe the transformations used to create the series. They then use transparency paper to verify their conclusions. 

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

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. 

What do you get when you cross a circle and a line? One, two, or maybe no solutions! Teach learners to find solutions of quadratic and linear systems. Connect the visual representation of the graph to the abstract algebraic methods. 

Systems of parallel lines have no solution. Pupils work examples to discover that lines with the same slope and different y-intercepts are parallel. The 27th segment of 33 uses this discovery to develop a proof, and the class determines...

What does similarity have to do with the Pythagorean Theorem? The activity steps through the proof of the Pythagorean Theorem by using similar triangles. Next, the teacher leads a discussion of the proof and follows it by an animated...

Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

Of course you're going to be solving an equation—it's algebra class after all. The 14th installment of a 35-part module first has pupils converting logarithmic equations into equivalent exponential equations. The conversion allows for...

Discover the extension of parametric equations to model linear transformations. Scholars first write parametric equations to model lines through two points. They then find the parametric equations that represent a linear transformation.

Mathematics set notation can be represented through a computer program loop. Making the connection to a computer program loop helps pupils see the process that set notation describes. The activity allows for different types domain and...

What constitutes a fair game? Scholars learn about fair games and analyze some to see if they are fair. They extend this idea to warranties and other contexts.

Pupils continue the study of ratios by creating ratios from a context. The contexts present more than two quantities, and scholars create contexts that match given ratios.
