The current paper presents a…

Mathematics interventions aimed at accelerating the learning of students with mathematics difficulties (MD) should be developed through a design science approach such as the Curriculum Research Framework (CRF). Precision Mathematics is a National Science Foundation-funded DRK-12 Design and Development project focused on building mathematical…

Teachers are asked to examine the potential opportunities for connecting themes of childhood play to the skills, habits of the mind, and principles of the disciplines.
