Number Sense
A “good intuition about numbers and their relationships. It develops gradually as a result of exploring numbers, visualizing them in a variety of contexts, and relating them in ways that are not limited by traditional algorithms” (Howden, 1989).

Understand numbers, ways of representing numbers, relationships among numbers, and number systems
Count with understanding and recognize “how many” in sets of objects
Develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.

Writing Numerals
Start with very clear, very strong models.
Focus on one number at a time.
Provide maximum guidance at first.
Be accepting of initial efforts.
Gently reduce the amount of guidance.
Reward correct performance.
Review previously-learned material at regular
intervals.
