Laughter is one of Gregg Lasher's favorite teaching tools to use in his geometry classroom at Boca Raton Community High School. The unique way Mr. Lasher gets his students interested in math is why a parent nominated him for this week's Thank a Teacher award, including a $250 check from HCA Florida Healthcare.
