Turkey Touchdown
Touchdown! A Thanksgiving Day, football-themed learning game challenges mathematicians to answer addition, subtraction, multiplication, and division problems. After five correct answers, players aim and kick a field goal before the next...
Curated OER
Composition of Reflections
Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.
Curated OER
Transformation
Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...
Curated OER
Fractal and the Dragon Curve
Students explore Fractal designs. In this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.

Everything You Wanted to Know About Symmetry
Second graders, in groups, rotate through four workstations that reinforce the concept of symmetry. They spend about fifteen minutes at each workstation.
Curated OER
Pretty Patterns
Students discuss shape and number patterns and play a game practicing completing patterns. Then they rotate through five workstations that reinforce the concept of patterning.

Tessellation Sensation
Geometers investigate patterns and symmetry, and examine the artwork of M.C. Escher on the Internet. They compare his style to the floor and ceiling tiles in the classroom. If you have ImageBlender™ software, you could have your class...
Curated OER
Spiders' Wheel
Students engage in a lesson which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to gain practice.
Curated OER
Transformations
Seventh graders complete activities to perform transformations of various figures and describe the transformations. For this transformations lesson, 7th graders perform a translation, a rotation, and a reflection on graph paper. Students...

Powerful Polygons
Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...
Curated OER
Triangle Congruence
Students use web applet to create congruent triangles. In this geometry lesson, students differentiate between congruent and similar. They create shapes online and drag those shapes around to create visuals of triangles.
Curated OER
Introducing Tessellations
Students create tessellations to increase their knowledge of the applications of geometry. They explore the different shapes of polygons.
