  8. Counting with understanding and recognizing "how many" in sets of objects • Using multiple models to develop initial understandings of place value and the base-ten number system • Developing understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections NCTM 2010

  9. Number Sense Number sense is an understanding of number concepts, place value, and computation. Losq (2005)
