Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

Fifth graders study reflectional symmetry and rotational symmetry. They go outside and explore symmetry in the environment. They come back inside and make symmetrical masks that represent their way of life.

Teach your learners how to investigate the relationship between a central angle and an inscribed angle which subtend the same arc of a circle. The dynamic nature of Cabri Jr. provides opportunity for conjecture and verification.

Learners investigate properties of the unit circle using sine, cosine and tangent. They analyze the answers to questions about the unit circle based on a right triangle.

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

First graders listen to and discuss the book, The Time Song. In this math instructional activity, 1st graders discover what they can do in a second, a minute, and a hour. Additionally students create a flap book to display time...

Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.

Students complete a unit about transformations and tessellations. They explore various tessellation websites, determine which shapes tessellate, complete a log about which website activities they complete, and create a tessellation...

Students discover the characteristics of polyhedra. Through hands-on activities and interactive videos, students investigate and retrieve information on polyhedra and crystal structures. Students study angles and symmetry. They...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

In this Pythagorean theorem worksheet, 9th graders solve and complete 8 different types of problems. First, they go to the given website and copy the picture shown. Then, students draw a right triangle using the straight line between the...

In this modeling a planetary nebula worksheet, students use a diagram to calculate the intensity at different radii from the center of the nebula. Students use the Pythagorean Theorem to determine the distance between two points on the...

Students explore types of water reserves. In this water conservation instructional activity, students brainstorm ways water are used in their homes. Students use a graduated cylinder to simulate the amount of water on Earth and the...

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Students explore symmetry in architecture.  In this cross curriculum art  and architecture lesson, students fold paper to illustrate symmetry and identify symmetrical and asymmetrical shapes.  Students observe photographs...

In this surface area worksheet, students solve 6 short answer problems. Students determine the amount of gift wrap paper needed to cover a rectangular box using surface area formulas.

Students investigate different online tutorials as they study graphing. In this graphing lesson, students apply the concept of graphs cross curricular and use it to make predictions. They define the purpose and theories behind graphs.

Elementary school learners investigate the attributes of a square. They discover that squares are polygons and examine squares found in everyday life. They concentrate on connecting the word, square, with the shape. As an...

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Students use NASA drawings to build a model satellite for a specific mission. They design a set of drawings for their satellite showing its subsystems as well.
