Dawn Koberstein

Dawn Koberstein believes that attitude is everything. One of the most important ways families and educators can reinforce mathematics achievement is simply by having a positive attitude that children can and will master challenging math. Too often, we undermine our children’s interest in math by using statements such as ‘math is hard’ or ‘I didn’t like math either.’”  Research shows that when we believe all children can learn challenging materials and we set high expectations, children rise to the occasion. Dawn has a way of making math seem ‘magical’ both to her students  and in her presentation style. With Dawn, math comes alive! Currently she is serving as the Dean of Students at Hull Elementary in Chandler halftime as well as serving as Teacher on Special Assignment the other half. She holds a Master’s degree. She spent the past four years as a Math Coach strenghening math instruction at her site and as a Math Teacher Leader in her district. She has 16 years of experience teaching and working with students in grades K-6.
