Welcome to the firstofitskind math video lessons, filmed in a LIVE classroom! The idea of capturing the classroom's energy and fun was born on one of Robert Ahdoot's trips abroad. Since then, YAY MATH has celebrated its fifth year as word has rapidly reached schools and students around the world. Yay Math, and YAY YOU!
Our Project Heather fundraiser has been an incredible success! My heart soars with gratitude to all of you. We truly helped the most wonderful family in their greatest hour of need. YAY US!
Here are some other fantastic clips documenting the inception and progression of this vision.
