Students solve abstract rate problem. In this algebra instructional activity, students solve problems with distance and rate. They create a table, solve for the missing part using an equations and analyze their results.

High schoolers create an abstract work of art that is made by repeating geometric shapes and lines, write concise instructions to reproduce the work of art and reproduce someone else's artwork via written instructions.

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Discover how algebra tiles help evaluate expressions. Scholars learn to use algebra tiles to substitute values in for variables and evaluate expressions. The included worksheet contains a set of evaluation problems to assess individuals'...

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

In this multi-faceted introduction to pi, participants perform a bevy of pi-related activities. Ranging from measuring household items to singing pi songs and reading pi stories, this fun and non-intimidating resource serves to bring up...

Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

The matrix — it's not just a movie. The lesson introduces the concept of 2 x 2 matrix multiplication as a way to represent linear transformations. Class members determine when a linear transformation represented as matrix...

Students reflect on the uses of mathematics in their daily lives and work in pairs to design brochures that make specific mathematical concepts clear and interesting to a popular audience.

Learners explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

Measure that shadow, and you'll find the height of the building! Learners study concepts related to right triangles during this extended unit project. They identify right triangles in the world, find heights of objects using similar...

Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.

Bring the concept of conditional probability alive by allowing your classes to explore different probability scenarios. Many tasks have multiple solutions that encourage students to continue exploring their problems even after a solution...

Using the concept of a candy vending machine, young mathematicians explore the sugar ratios found in different types of candy. Using the provided information, class members calculate and compare different ratios in...

Young scholars demonstrate different algebraic equations using Borenson's Hands-On Equation materials. They work in a cooperative group to solve algebraic equations.

Young scholars construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using...

Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...

Students gain a concrete introduction to the concept of ratios. They demonstrate the ability to create ratios using peanut butter and jelly. They, in groups, construct 6 different sandwiches using different amounts of each food.

Students investigate shapes and patterns. In this algebra lesson, students move from concrete to abstract understanding of shapes and concepts. They use variable to identify the unknown.

Students examine the concept of perimeter. Students calculate the perimeter of a random shape on a grid. Students develop a better understanding of the concept of perimeter. Students calculate the perimeter of shapes.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Seventh graders investigate some concepts associated with geometric shapes. They study the bisector segment and the perpendicular line to a given line. Students conduct analysis with the goal of deepening observation and deduction...
