Modifications for ELL: Saraswati Noel, Seattle World School, Mathematics teacher  (30 minutes)
Join in a fun activity to create a feel for the struggles English Language Learners encounter in our math classes.  Leave with strategies of how to modify your lessons to help ELL students as well as the other students in your classes.

Julia Robinson Festival Rich problems:  Art Mabbott, Scholars Online (70 minutes)
The 2015 Julia Robinson Festival for 4th - 12th grade students will be Saturday, April 4th at the University of Washington.  We will try out one or two of these fascinating problems. Surprisingly,  they are easily accessible to 4th graders, but are interesting enough to captivate PhD mathematicians, sometimes for days!  Come, join in the fun! 

Hands-on 3D Geometry:  Mircea and Cristina Draghicescu, from ITSPHUN, (70 minutes) http://itsphun.com/education.html (check out the amazing shapes on their website!)
Use ITSPHUN interlocking shapes to build models of polyhedra with regular faces and explore their properties.  Build some of the highly symmetrical objects that fascinated humans for hundreds or even thousands of years.  Topics include convexity, Euler's polyhedron formula, duality, chirality, transformations, and symmetry groups.
This is the same workshop that was presented at the Museum of Math in New York City in February!

Afternoon Session:  1:00 – 4:00 pm

Combining Transformations to Explain Theorems about Polygons: Jim King, UW Math, retired
If we move a shape in the plane by a sequence of two rotations, is the resulting motion just a single rotation?  If so, how can we find the center and the angle? Knowing the answers to such questions provides a powerful tool for proving theorems about triangles and other polygons.  We will learn how to answer these questions and then apply them to get some very pretty theorems about triangles and other polygons.  We will explore this topic with some symmetry patterns, some scissors, and a bit of technology. (60 minutes)

Dissections of the cube:  Joyce Frost, Lake Washington HS, retired
Using Mag blocks, paper folding, and the dimensions of the cube, we will create cool dissections of the cube and create a visual proof (or two!) of the formula for the volume of a pyramid.  Caution:  these activities could prove addictive!

Local Hosts: Clint Chan, Joyce Frost
