PRODUCT DESCRIPTION

Simply copy and use these comprehensive sketch notes for number theory including a sieve of Eratosthenes, prime factorization, GCF and LCM. Included are two different practice activities and patterns and an idea for an art activity to support your lesson. My students love this unit - maybe because I bring in birthday cake to eat while we learn the birthday cake method of prime factorization. :-) You will be so thankful for this product!

Sieve of Eratosthenes to determine prime/composite numbers from 1-100
Prime Factorization notes: birthday cake and factor tree methods
GCF notes
LCM notes
Partner practice cards with GCF
Graphic Organizer for practice
Monomial Spinners to use with pre-algebra / algebra students - find GCF of monomials
