Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...

Class members complete an assessment task by identifying whether statements about triangles and quadrilaterals are always true, sometimes true, or never true. They then participate in a sorting activity with the same objective.

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.

Learners explore line(s) of symmetry in polygons during a hands-on activity and a Student Web Lesson. They build a wall of symmetrical shapes designed and drawn by students.

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.

High schoolers discover properties of parallelograms as they construct a parallelogram using Cabri Jr. They will measure angles and side lengths of their construction and determine the relationship between the diagonals of a...

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.

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.

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.

What does it mean for a quadrilateral to be cyclic? Mathematicians first learn what it means for a quadrilateral to be cyclic. They then investigate angle measures and area in such a quadrilateral.

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.

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 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.

Scholars explore parallelograms in this geometry lesson. They investigate the properties of a parallelogram. Assisted by technology, your learners will construct a parallelogram and examine the sides, angles, and diagonals to discover...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

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...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Students analyze the patterns in polygons and relate it to the rate of change. For this algebra lesson, students discuss the relationship between the data and the graph of the data.

Sixth graders use geoboards and dot paper to experiment with geometric concepts. In this geometry lesson, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and finding the area...

Rhombuses, rectangles and squares are have special properties. In this lesson, young geometers investigate and make conjectures about diagonals, angles, and parallel lines of parallelograms.
