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,...

Your learners will be tantalized by this inquiry-based, collaborative activity as they discover how to write an equation that represents the height of an ice cream cone. Given the scenario based on the poem, "Eighteen Flavors," and...

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

Young scholars define the different methods used for optimizing a particular element of a problem. In this optimization problem lesson, students optimize appropriate details of a problem using data collection, algebra, technology, and/or...

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...

Solve inverse functions through graphing and algebra. High schoolers will graph inverse functions and use the correct notation to write the equation. They observe a graph and write an equation for the function. In the end, they will be...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Students participate in paper recycling. They are taught to environmental awareness of recycling and its importance in their future. Students discuss and identify the problems of how they can minimize waste. They brainstorm suggestions...

Students create paper bridges. In this geometry and architecture lesson, groups use legal paper and paper clips to design a bridge that will hold 100 pennies. Links to mini-lessons exploring stability of different geometric figures and...

Seventh graders explore rational numbers. In this fractions, decimals, and percents instructional activity, 7th graders identify and compare equivalencies between fractions, decimals, and percents. Students use hands-on activities to...
