Math: 1st Grade. 1st graders continue to develop their addition and subtraction skills, gaining a deeper understanding of the concepts as they practice and gain mastery of these skills. In many classes, math tools and manipulatives, such as blocks, tiles, and different shapes are used to help students practice math using concrete, visible objects.
Math Teacher. Students in the United States begin studying mathematics at around five or six years of age, continuing through secondary school and into higher education. In elementary school, children are introduced to basic mathematics, and the theories and methods covered in math classes become increasingly complex as students age. Many schools will offer different levels of classes as students may show a greater or lesser aptitude for complex math courses.
