2. Brief Summary According to Hill and Ball (2009), good teachers know both content and how to make it understandable and accessible for their students. Specifically, teachers of mathematics at all grade levels need to possess mathematical knowledge that will enable them to respond to students’ questions and be able to explain a concept using various representations that are mathematically accurate and helpful to learners. Mathematical Knowledge for Teaching (MKT) correlates with “certain habits of mind such as careful attention to mathematical detail and well-explicated reasoning” (p.70). Teachers of mathematics can develop MKT by developing their own knowledge through extensive mathematics-focused professional development. In addition, those who prepare teachers and provide professional development will need adequate support and guidance in effective ways to gain MKT in order to put together meaningful opportunities. Skillful teaching will translate into better instruction for our students.
