  • count, with and without objects, forward and backward to at least 20.
  • recognize that a number can be used to represent how many objects are in a set or to represent the position of an object in a sequence.
  • compose and decompose numbers up to 10 with objects and pictures.
  • develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.
  • connect number words and numerals to the quantities they represent, using various physical models and representations.
