Prime or Composite and Prime Factorization

Bell Ringer:  SET Game

Lesson Frame:

We will take notes on prime numbers, composite numbers, and prime factorization.

I will show the prime factorization of the number 48.


Today was all about note taking.  We began by adding divisibility rules to our math journal.

Next, we spent time defining prime and composite numbers and connected them to finding factors using the divisibility rules.  I chose to record our note taking with Screencastify so that any students who were absent would be able to add the notes to their journal.  Also, students can re-watch the recordings to deepen understanding (hopefully).

After finishing the prime and composite notes, we moved into Prime Factorization:
