Primes
	Novice 1 pts	Apprentice 2 pts	Proficient 3 pts	Above Proficient 4 pts
Prime Factorization	Novice Missing many elements or not completed. numbers are not primes.	Apprentice Missing one or two required elements. some of the numbers are primes.	Proficient Includes all required elements; factors are all primes.	Above Proficient Includes all required elements; factors are all primes. Primes are written twice with the second set using exponents
Mathematical Thinking	Novice Two items (Factor tree, GCF, or LCM) are incorrect. Math work does not shows mathematical thinking	Apprentice One item (Factor tree, GCF, or LCM) is incorrect. Math work shows limited understanding.	Proficient All items are accurate, explanations demonstrate Mathematical thinking.	Above Proficient All items are accurate, explanations demonstrate a deeper understanding and mathematical thinking
Stratagies	Novice Use of a strategy is not evident or is used incorrectly	Apprentice Strategy used is appropriate but is incomplete	Proficient Strategy used is appropriate and results in finding the GCF and the LCM	Above Proficient More than one strategy was used to demonstrate a deeper understanding of how each strategy can result in finding the GCF and the LCM.
