Students analyze a drawing of a regular octagon inscribed in a circle to determine angle measures, using knowledge of properties of regular polygons and the sums of angles in various polygons to help solve the problem. They use...

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students investigate one, two and three dimensional objects. In this algebra lesson, students differentiate between different shapes of objects and write equations to represent each. They start with what they already know and prove...

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

Third graders use nonstandard concrete methods to estimate and record measurements of their body.

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...

Hook your charges on how to solve a real-world art problem with mathematics by showing works of Christo. You can find eye-catching images on the Christo and Jeanne Claude webpage. Here, math learners help Jean Claude and Christo prepare...

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Pupils engage in a lesson that uses applied mathematics to find the solution to the design of a pool for a home. They design the pool based upon scale measurements that include perimeter and area of the pool area, water volume, and...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

Eighth graders participate in the mini-metric Olympics. For this measurement lesson, 8th graders solve real-world problems that require them to calculate length, area, and volume in metric units.
