Students calculate the area of different polygons. In this geometry lesson, students find the area for trapezoids, rhombuses and kites.

High schoolers identify the number of diagonals for each polygon. In this geometry instructional activity, students identify the polygons based on their diagonals and the way it intersect. They create visuals using the navigator to see...

Students investigate density using film canisters filled with different density materials and larger objects of varying density. In this density lesson plan, students discuss the concept of density and rank film containers from dense to...

Students identify different properties of parallelograms. In this geometry lesson plan, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.

Students analyze how the parts of a system go together and how these parts depend on each other. They comprehend the forces in terms of strength and direction. Students observe, measure and describe weather indicators.

Students identify the properties representing quadrilateral. For this geometry lesson, students differentiate between special and regular quadrilaterals. They discuss and demonstrate hierarchy of quadrilaterals.

Learners use construction technology to identify and find relationships between the attributes of various quadrilaterals. They make and test conjectures about the distinguishing properties of parallelograms, rectangles, rhombuses,...

Students investigate the properties of quadrilaterals. In this geometry instructional activity, students solve problems dealing with construction and designs. They work with quadrilaterals, midpoints and parallelograms.
