Tenth graders construct geometric figures using compasses and protractors.

Students experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate when...

Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Students use problem solving skills, formal geometry, and The Geometer?s Sketchpad. They model and solve two real-world problems by constructing the in center and circumcenter of triangles.

In this number recognition worksheet, students read the descriptions of the math terms and try to guess what each term is. Students circle the third letter in the boxes to check their answers.

What type of quadrilateral is that? Discover the difference between the types of quadrilaterals. Small groups investigate types of quadrilaterals using geometry software to find their properties. To keep track of the different...

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

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...
