Four video feature a series of third/fourth grade lessons designed to support students as they explore the relationship between ways of counting and mathematical expression. Students share different strategies and engage in classroom discussions that surface:

  • mathematical expressions can be used to represent various ways of counting
  • ways of counting can be inferred from given mathematical expressions
  • what each number in the mathematical expression is representing

A document outlining the background and research on the content and standards, unit/lesson goals, and unit/lesson plan accompanies the video
