Day Five: GCF and Toss and Talk

Today in Math 6, students in  and  expanded their use of prime factorization by using the algorithm to compute two or more whole number's greatest common factor (GCF).  Please refer to the video posted below to help you understand today's algorithm.

During Math 6 - 2°, students completed a Socrative quiz dealing with exponents and order of operations on the Chromebooks.  Students then worked in groups of two, three, or four to evaluate numerical expressions using the order of operations playing a game called "Toss and Talk".  Mrs. Long and Mr. Giomini circulated around the room and asked students to explain their algorithms as the game progressed.

Today in Math 6+, students used their previous day's knowledge of prime factorization with greatest common factor (GCF) and least common multiple (LCM).  Mr. Giomini then assigned the Khan Skill GCF and LCM Word Problems to complete in class.  He circulated the class noting the student's progress as they worked independently. 

Today's Learning Target(s): The student will be able to...
  1. fluently add, subtract, multiply, and divided whole numbers using the standard algorithm for each operation.  (Math 6-2°)
  2. decompose a whole number to its prime factorization.  (Math 6 - 1 and 3° and Math 6+)
For Evening Practice, the student is expected to complete:
  1. complete ten minutes of meaningful practice on Khan Academy.
  2. Math 6: page 16
  3. Math 6 - 2°: 10 minutes of Khan
  4. Math 6+: page 18 and 22
