This number system lesson teaches students how to find the greatest common factor of two whole numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students find the greatest common factor of two whole numbers by finding all the factors of both numbers and comparing them.  This lesson also includes real-world word problems for students to solve.

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.

This number sense lesson focuses on reducing fractions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students find the factors of the numerator and denominator. Then, they identify the greatest common factor (GCF) and write it down. Finally, they reduce the fraction by dividing the numerator and denominator by the GCF and interpreting the reduced fraction. In addition to the lesson, there are five pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items and 10 flashcards for reduced fractions.
