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...

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 identify properties of parallelograms. In this geometry lesson, students label polygons as parallelogram or not. They define and label the properties of a kite.

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

Pupils sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.
