Flexible Math Concepts and Concept Quests were borne from collaborative work between Kim Markworth and a local school district. Together, we strove to meet the differentiation needs of classroom teachers and students' desires to be challenged in mathematics through the implementation of Concept Quests. Flexible Math Concepts seeks to support other teachers and districts' differentiation needs by spreading Concept Quests!
