A retired National Board Certified Teacher from California has started a Web-based elementary-level math-consulting business called Math Games and Activities. Bonnie Adama, who taught for 19 years, now teaches elementary-school math teachers and parents how to use games and activities to help students learn. "She is just a gem," one educator said. "She really has great rapport with teachers. A lot of teachers, when you say Bonnie's name, they give you a big smile because she's changed the way they look at teaching."
