Middle schoolers investigate some of the mathematical concepts involved in the study of circles. They first practice finding the circumference of a circle by finding the diameter and performing the calculation. The lesson delivery is...

Students investigate shapes. In this dimension and orientation of shapes lesson, students identify and color shapes, use shape stamps to form animals, glue shapes together to make other objects and describe how shapes are used.

In this coordinate grid graphing worksheet, students plot the given points onto each of 6 coordinate grids. All points are located in quadrant 1. One point is plotted on each grid. Answers are given by clicking the appropriate place on...

Learners solve systems of equations. In this precalculus lesson,students solve linear equations using matrices. They use the Gaussian elimination method to identify the missing variables and simplify the linear equations.

Students solve problems involving triangles. In this geometry lesson, students apply properties of triangles to find the missing angles and sides. They identify angles of parallel lines cut by a transversal.

Students use a shoe box to create a seafloor model and use cardboard for layering inside of the shoe box to simulate the ocean floor. They probe the ocean floor to simulate sonar echoes. Finally, students graph their data to get a...

In this geometry worksheet, students create a map that uses various geometrical concepts. The final project is the creation of a "geometrical town." Rubric for grading is included.

In this geometry activity, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

Pupils examine how archaeologists preserve context of sites through use of rectangular grid or Cartesian coordinate system, and develop sense of distance by pacing off and estimating distances.

Fourth graders discover how to apply the Cartesian coordinate system by figuring out the length and width of their school playground. They determine that pacing is an important tool for the initial mapping of a site. Students conduct a...

Students establish a grid system over an archaelogical site. They label each grid unit. They determine the location of artifacts within each grid unit. They construct a scientific inquiry concerning the location of artifacts on the site.

Second graders participate in a class discussion and view a traffic safety video dealing with crossing the street safely. They discuss the steps taken in order to cross the street safely and then analyze the benefits of walking and...
