Tenth graders construct geometric figures using compasses and protractors.

In this math vocabulary worksheet, students choose which multiple choice answer best defines twenty-five mathematical terms. Students place their answers on the lines provided.

In this congruent figures worksheet, students answer ten true or false questions. A sample question reads: "Two triangles are congruent when their shape and size will be the same."

Students identify and use the similarity theorem. For this geometry lesson, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.

Seventh graders investigate geometric shapes using tessellations. In this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Students utilize online research skills to surf the Internet and complete an online scavenger hunt to find the answers to various mathematical questions.

Students construct a barrel or other curvy container and then estimate and gauge its volume.
