Multiplication and division are a major focus in fourth grade. Students reason about numbers and their factors and multiples. They use models, representations, and story context to help solve multiplication and division problems. They are expected to know the multiplication facts to 12 x 12 by the end of fourth grade and work on a variety of multi-digit strategies for addition, subtraction, and multiplication. Fourth graders develop their understanding and knowledge about fractions.

In fourth grade students analyze tables and graphs, examine rates of change, and develop an understanding of data by collecting, representing, describing, and interpreting numerical data. They combine measurement and geometry when learning about the area and perimeter of rectangles.
