Prime, Composite, Prime Factorization: Rotation Day C

Bell Ringer:  Guess My Number

Image Credit

Students are given a series of clues to determine a mystery number.

Lesson Frame:

• We will work on activities that reinforce our understanding prime numbers, composite numbers, and prime factorization.
• I will analyze a number using divisibility rules to determine if it is prime or composite.

Lesson:

Group 1 spent their first rotation in Content Mastery working on intervention activities. Their second rotation was with me. We did the "cootie catcher" prime, composite, and prime factorization activity.

Group 2 & 3 each completed an activity called "P.C.'s Ideal Job" from The Mailbox Magazine, the rest of the time was spend on Think Through Math.

Group 4 worked with me and the "cootie catchers" and then time on Think Through Math.

Assignment:

I wanted some feedback on how students are doing with prime, composite, and prime factorization, so I created a form with questions for them to solve. I used "Identify Prime and Composite Numbers" from TPT for most of the questions, but supplemented a few of my own questions requiring students to use a factor tree to determine the prime factorization.

Close

I actually included the close within the assignment. I gave my students the number 48 and asked them to determine which divisibility rules worked and if 48 was prime or composite.
