In mathematics, teachers concentrate on teaching a more focused set of major math concepts and skills. This allows  students time to master key math concepts and skills in a more organized way throughout the year and from one grade to the next. Teachers use rich and challenging math content to engage students in solving real-world problems and to reason logically in order to inspire greater interest in mathematics. Conversations about math and collaboration with peers is another component of engaging, hands-on math instruction that builds conceptual understanding.
