Prime Factorization Practice with Partners
Prime Factorization Written in Expanded Form and with Exponents

Leads to Great Math Discussion and Error Analysis

Each student has their own sheet with a factor tree started for them. Partners should get the same answer, so it's a great way for students to be using math talk and check to see if they got the correct answer.

Students work in pairs to find the prime factorization for different numbers. Each student solves their first problem (same number on both sheets, different factor tree). Once both are finished, the partners check with each other to see if they got the same prime factorization. If their answers are the same, they can start the next problem. If the answers are not the same, there is an error in someone's work and the they must work together to find where the mistake was made.
