Week 3

(Module 1 Topic 1 Lesson 2-3: Factors + Multiples)

Learning objective = Students create rectangles with given areas and relate their dimensions to factors and common factors. They use prime factorizations to determine the greatest common factor (GCF) and least common multiple (LCM) of two numbers. Students examine the rows and columns of an area model to identify multiples and the LCM. They describe the relationship between the product, the GCF, and the LCM.

Repeated explanations, practice opportunities, and regular feedback:

Parents can support learning at home by helping students connect this week’s lesson to real-life examples and practice explaining their thinking. Encourage your child to explain each step aloud rather than simply memorize a rule = SAMPLE TEST QUESTIONS + MORE QUESTIONS

***If your child needs more challenge, they can move at a faster pace by using this site to study the concepts of future lessons. Mr. Pierre will strive to prepare lessons two weeks ahead of the current week. Also, Khan Academy is a great enrichment resource***

How Many Hot Dogs And Buns Should He Buy? - Robert KaplinskyThis real-world problem-based lesson challenges students to determine the number of packages of hot dogs and buns a person should purchase.

Arranging Desk: Factors and Multiples | Cyberchase | Grades 3-5, 6-8 Number of Objects in Rectangular Arrays (Grade 2) Teaching and Lesson ResourcesIn this video segment from Cyberchase, Harry takes on a job as a substitute teacher. After moving all the desks to create space in the middle of the room, Harry displays his juggling talent. When putting the desks back into rows, the class is faced with the task of creating rows with an equal number of desks. In doing this, the students learn about the factors of twenty-four.

Greatest Common Factor | Grades 3-5, 6-8 Greatest Common Factors and Least Common Multiples (Grade 6) Teaching and Lesson ResourcesIn this video, learn how to find the greatest common factor of two numbers. Then, see how this can be used to solve problems with large numbers. In the accompanying classroom activity, students learn to find prime factors using factor trees. They then learn how prime factors, a Venn diagram, and simple multiplication can help them find the greatest common factor of two numbers. The lesson challenges students to find the greatest common factor of increasingly large numbers. It also pushes them to think about how prime factors are the building blocks of composite numbers.

Multiples and Movement | Camp TV | Grades K-2, 3-5 Applying Properties as Strategies (Grade 3) Teaching and Lesson ResourcesPractice multiplication while moving your body with this video from Camp TV. This video from Move to Improve combines aerobic fitness with a fun math lesson.

Multiplication Fluency | Grades 3-5 Multiplying and Dividing Within 100 Teaching and Lesson ResourcesYour child’s introduction to multiplication is through repeated addition. He will draw an array to visualize, or see, five groups of four stars. He will count the stars and find the total.As his understanding improves, he will skip count to find the total more efficiently. Your child will use a variety of visual models, to represent multiplication as he works toward developing multiplication fluency.Fluency in third grade means knowing, from memory, all products of two one-digit numbers. This includes facts from zero times zero all the way up through nine times nine.Then, your child will use these facts to develop the connection between multiplication and division. Knowing that five times four equals twenty is the first step in understanding that 20 stars, divided into five groups, equals four stars in each group. Or, twenty divided by five equals four.Talk about the relationship between multiplication and division with your child. I know this… So I also know this! With lots of practice, your child will achieve fluency!And that’s good to know.
