Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, young scholars use the TI to create a visual of their shape.

Students find the diagonals of the quadrilaterals. In this geometry lesson, students identify and use properties of quadrilaterals. They define different parts of a quadrilateral shape.

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

Students find the length of diagonals.  In this Pythagorean theorem instructional activity, students use the Pythagorean theorem to determine the length of diagonals. 

Students identify the number of diagonals for each polygon. In this geometry lesson, students identify the polygons based on their diagonals and the way it intersect. They create visuals using the navigator to see the changes in the shapes.

Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

High schoolers calculate the determinant. In this algebra lesson, students find the determinant and use to calculate the area of a triangle. They calculate the area of a quadrilateral in a plane.

Sixth graders toss popcorn kernels at a 12? circle inscribed in a 12? square. By counting the number of popcorn kernels that land inside the circle and inside the square the students calculate estimates for the value of pi.

Students identify the different properties of quadrilaterals. For this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

Students analyze the measurements of rectangles. In this analysis lesson, students will investigate patterns by looking at ratios. Students will also hypothesize the probability of a ball going into a certain pocket when playing pool....

In this understanding triangles instructional activity, students read 6 pages of examples and explanations about identifying triangles, determining length of sides and degrees of angles, including the hypotenuse, then answer 28...

Students identify interior and exterior angles of polygons. For this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.

Pupils 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 calculate the area of a parallelogram. In this geometry lesson, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Fourth graders investigate regular polygons. In this regular polygon lesson plan, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
