Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Students explore the concept of sine and cosine.  In this sine and cosine lesson, students work in groups to graph sine and cosine functions.  Students examine how coefficients in various parts of each parent function shift the...

Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

Learners prove and apply theorems of triangle inequality and hinge theorem. In this geometry lesson, students will discuss which triangle is bigger and why. They will use theorems, such as Exterior Angle Inequality or the Pythagorean...

Hammer away at building different types of functions. An engaging lesson builds on learners' knowledge of domain and range to create an understanding of composite functions. Young scholars learn to write composite functions...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Students study basic recursion by exploring patterns in the data they generate from two simple probability-based experiments. In the first, students flip a coin to discover how many times they must flip it before it lands on "heads."...

Young statisticians are introduced to box plots and quartiles. They use an activity and discussion with supplemental exercises to help them explore how data can be graphically represented.

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their ciphers...

Middle schoolers brainstorm pizza toppings and determine the number of possible ways to order a pizza. For this algebra lesson, students analyze and investigate geometric patterns as they relate to the concept of a variable. Middle...

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Seventh graders analyze responses to different types of problems. Using pictures and diagrams, they explore and model the division of fractions. Students examine situations that call for division whether with the whole numbers or with...

Students are introduced to the meaning, symbolism, and value of the quarter. They determine the percentage of total monetary value held in quarters and graph the results. Students infer about the U.S. Mint's distrubution of coins. They...

Students compute the length of time it will take to save enough money to purchase a yo-yo. For this math lesson, students create a design with pennies and write the associated linear equation. In this linear equations lesson, students...

Students examine the concept of scatter plots. They compare baseball statistics to locate the ones that correlate with winning, and identify the positive, negative, and no correlation in sets of data using MS Excel.

Learners study the history of kites and their fundamental properties.  In this kites lesson students divide into teams and build and fly kites. 

For this math worksheet, middle schoolers solve the problems for the quadratic equations. They factor the equations and determine the probability of the two solutions.

Students apply an algorithm to measure the distance to stars in the night sky. In this photometry lesson, students observe stars in the night sky as they measure the distance to them and to the cluster, The Milky Way. They apply the...

Learners create spreadsheets which will display and figure mean, median, and mode of a set of numbers.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students calculate ratio and proportion. In this unit rates lesson, students estimate using proportions and find their errors in doing so. They calculate unit rates and define the concept of unit rates.

Mixing math and art is done in this activity by applying graphing knowledge to create a unique piece of art. This activity varies acording to the graphing knowledge of the artist. First, learners identify and review various types of...
