Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Here is a lesson on coordinates that has pupils view three Cyberchase video clips illustrating the definition of "point" and "line." Along the way, learners will discuss what characters from the videos do, and where problems lie in...

Your geometry learners will discover and show the construction of the circumcenter of a triangle. Guided by the steps in the activity, they construct perpendicular bisectors of each side that have a point of concurrency called the...

Your learners will practice many ways of describing data using coordinate algebra in this unit written to address many Common Core State Standards. Simple examples of different ways to organize data are shared and then practice problems...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Students investigate the elements of a pattern.  In this geometry lesson plan, students identify different shapes in a pattern and discover which shapes are missing in order to extend it.  Students create their own patterns...

First graders explore 2-dimensional and 3-dimensional shapes. In this geometry lesson, 1st graders examine the attributes of 2 -dimensional and 3-dimensional shapes. They also create the shapes as they build models. This lesson...

First graders combine different shapes to create an image.  For this geometry lesson, 1st graders utilize squares, circles, rectangles, triangles, and arc to draw a picture.  Students share their creation with their class...

Fifth graders complete activities to investigate parallel and perpendicular lines. In this plane geometry lesson, 5th graders watch a movie about parallel and perpendicular lines. Students work in pairs to describe and draw the lines in...
