분수: 최대공약수는 무엇인가? 최대공약수

Before the lesson begins the students will review the multiplication facts. I will show the students a multiplication fact and they will then say the answer to the problem. During the lesson I will be using Zoom whiteboard to demonstrate finding the greatest common factor. The class will be structured using questions and answers. Vocabulary words that will be taught are common factor and greatest common factor(GCF). To begin the lesson I will display 2 numbers on the whiteboard and the students will list all of the factors for each number. Then the students will find the greatest factor of the two numbers. Next, the students will find the greatest common factors of numbers using a factor tree for each number. I will use the I do, we do, and you do strategy for this lesson. The students will be given an opportunity to answer questions and solve problem on the whiteboard to show understanding.
