Students identify polygons.  In this geometric shape instructional activity, students explore the characteristics of polygons.  They identify polygons, and classify triangles according to their sides and angles.  Students...

In this angle worksheet, students answer forty mental math questions divided into four problem sets.  These problems require students to remember angle facts and so simple calculations mentally.

In this polygons worksheet, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.

Students play the "space-breaker" game, in which they are required to create a picture using shapes or lines called out to them) to reinforce the concept of geometric shape and line.

Learners complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.

In this measurement worksheet, students complete a 12 question multiple choice online interactive assessment about standard modern and ancient measurement.

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

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Students create a picture of an actual scene or overlap the called out lines or shapes into a space-breaker. If someone calls out a line or shape a student had not planned to use in the art, they have to figure out some way to use it...

This lesson focuses on polygons; a polygon is a closed, flat shape that has only straight sides. Polygons can have any number of sides and angles, but the sides cannot be curved.

Identify architectural structures and objects in the community that represent different figures and types of geometry and mathematics.
