This number sense lesson focuses on determining the prime factorization of numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students determine the prime factorization of the number using a factorization tree, factoring all composite numbers until they are prime. Finally, they write the prime factorization using exponents if necessary and checking and interpreting the answer. In addition to the lesson, there are twelve pages of Independent Practice and review with questions modeled after current adaptive testing items.

This number sense lesson focuses on determining the greatest common factor of two numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students determine the prime factorization of the two numbers and write the numbers as a product of prime factors. Then, they determine the greatest common factor by identifying the prime factors both numbers share and find the product of the shared factors, if necessary. Finally, they read the statement with the greatest common factor. In addition to the lesson, there are five pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
