Young scholars investigate circles and compound locus. In this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

Learners calculate the slope of parallel and perpendicular lines.In this algebra lesson, students differentiate between parallel and perpendicular lines. They graph their lines using the slope of the equation.

Students find the slopes for perpendicular and parallel lines. In this geometry lesson, students differentiate between parallel and perpendicular lines. They use Cabri software to create lines to compare.

Middle schoolers utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether...

Fourth graders become familiar with a chart and use the information to create a flight plan.  In this flight plan instructional activity, 4th graders access background knowledge of the role of flight controllers and the number...

Young scholars count, figure change, and find the value of saving in a classroom store.

Eighth graders draw right triangles and identify the parts of a right triangle: right angle, interior and exterior angles, hypotenuse and legs. They predict and identify any relationships that exist between the sides of a right...

Students discover the sum of the interior and exterior angles of several polygons. In this Geometers sketchpad lesson, students work in groups to find the stated measurements of triangles, quadrilaterals, pentagons and hexagons. Students...

Students investigate how to create a free standing structure. In this mathematics lesson, small groups of students demonstate how to build the tallest structure while spending the least amount of money on materials.

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...
