(1 minute)
The second module in Grade 6 is called Arithmetic Operations Including Division of Fractions. The module includes 19 lessons and is allotted 25 instructional days. It challenges students to build on understandings from previous modules through the introduction of division of fractions. Students clearly have experienced dividing a whole number by a fraction and a fraction by a whole number. The beginning of this module has students extending this knowledge to dividing fractions by fractions. The second topic of this module has students practicing previous algorithms of addition, subtraction, and multiplication of whole numbers and decimals, but extends to applying the division algorithm to divide decimals. Students rely on previous number theory to connect divisibility to determine the greatest common factor and the least common multiple of numbers. Students will connect the division algorithm to the Euclidean Algorithm as a tool for efficiently determining the greatest common factor of large numbers.

Topic D is composed of four lessons where students will be thinking logically about multiplicative arithmetic in order to connect back to the long division algorithm they worked on in Topic C.
(Click to advance slide) Lesson 16 is an exploration of odd and even numbers.
(Click to advance slide) In lesson 17, students will test the divisibility for the numbers 3 and 9 to finish off their study of divisibility. They will have a review of the divisibility rules from previous grades.
(Click to advance slide) Students use their knowledge of divisibility rules to explore finding the least common multiple of two numbers, as well as finding the greatest common factor of two numbers. This will prepare the students for understanding (Click to advance slide) Lesson 19 where students find the greatest common factor of two numbers using the Euclidean Algorithm. Students will use their understanding of the long division algorithm to find that using the Euclidean Algorithm is sometimes a more efficient means to finding the GCF of larger numbers.
Lesson 19: The Euclidean Algorithm as an Application of the Long Division Algorithm

Topic D: Participant Lesson Demonstration
Look at your number card. If you are a 16, go to your designated table. If you are a 17, go to your designated table, if you are an 18, go to your designated table.
Your group will have 7 minutes to read through the lesson you’ve been assigned.
You will discuss the representations and the flow of the lesson with your group.
After discussion, your group will present the outcomes of the
lesson and model one example from the lesson for the whole group.

Key Points
Students look for and uncover patterns while modeling quotients of fractions to ultimately discover the relationship between multiplication and division.
Students explore partitive and measurement interpretations of dividing fractions to make connections to the relationship between multiplication and division.
Estimation and place value enable students to determine the placement of the decimal point in products and recognize that the size of a product is relative to each factor.
Students learn to use connections between fraction multiplication and decimal multiplication.
Students connect estimation to place value and determine that the standard division algorithm is simply a tally system arranged in place value columns
Students make connections to division of fractions and rely on mental math strategies to implement the division algorithm when finding the quotients of decimals.
Students explore and discover that Euclid’s Algorithm is a more efficient way to find the greatest common factor of larger numbers and see that Euclid’s Algorithm is based on long division.
