Karen Wellington, a former high school mathematics teacher for the New York City Department of Education, uses origami as a hands-on activity to promote a deeper understanding of mathematics. She was originally attracted to origami because of its strong connections to mathematics and began incorporating it into her lessons on geometry and other mathematical topics. In addition to teaching, Karen was also a math coach for the Department of Education; in this position she helped math teachers develop engaging activities often incorporating origami into their math lessons.

In Karen's origami workshops, she guides participants through the creation process by using the language of mathematics to fold fun and attractive creations out of paper. Children and adults are able to develop a deeper understanding of mathematics because they are applying abstract concepts to the creation of concrete products. Karen has given workshops at schools, various Queens Public Libraries and senior centers. In addition to her workshops, Karen runs two origami clubs in Jackson Heights: one for adults and one for children

### WORKSHOP DESCRIPTION

**Origami Number Games**

In this workshop children will create the pieces for two games which they will play and also be able to take home. Creation of the game pieces will help children develop a better understanding of basic geometry concepts such as angles, polygons and congruency. Concepts covered in the workshops are based on the Common Core Standards for Mathematics. As the children play the games they are engaged in using their basic arithmetic skills and are led to a better understanding of prime and composite numbers.

**Using Geometry to Fold Origami Toys**

In this workshop the students will identify different types of angles and lines as they create a spinning top and fortune teller. They will also identify and classify different types of triangles. Concepts covered in this workshop are based on the Common Core Standards for Mathematics.

**Paper Engineering + Origami = (Fun) 2**

In this workshop you will learn how to use paper and geometry to build a spherical container in which you can store small items. The container is actually an icosahedron, which is a three dimensional shape made up of 20 equilateral triangles. We will use paper circles which we will fold into triangles and then use these to create the icosahedron. This container will look very much like a Geodesic dome, which is a structure made up of 100's of triangles and is used for special buildings, for example planetariums.

**The Math of Origami (Residency)**

By coordinating activities and projects with specific curriculum objectives, Karen Wellington will create a residency tailored to the skill level of your students. This program will broaden and develop students' understanding of geometry and other basic concepts included in the Common Core Standards for Mathematics. This series will include: Origami creations of geometrical objects such as cubes, prisms and pyramids, making game pieces for a mathematical activity, and toys such as a spinning top and a magic circle. This series can be created for Grades 3 through 6.
