Entry # 7 Operations & Algebraic Thinking: Gain familiarity with factors and multiples (4.OA)

Personal Objective: This week I explored gaining familiarity with factors and multiples at the 4th grade level. My goal was to create and gather clear visual and written examples that would make the subject area more accessible and fun for students.

Common Core Standard:
4th Grade: 4.OA

Gain familiarity with factors and multiples


4. Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

Reflection: While I feel that I have a clear grasp of factors and multiples it was helpful to start thinking of how I might go about teaching this material at the 4th grade level. Reviewing how to identify prime numbers was definitely a helpful refresher. While I don't always love the idea of rote memorization, when it comes to students learning factors and multiples it has its advantages. This being said, visuals and manipulatives like the Goldfish I used to depict the factors of 6 are helpful in establishing basic concepts when introducing the subject to students for the first time.

    Scott, I found it very useful to see factors and multiples next to each other. These two can be confusing and your visuals are very informative. I like the goldfish because it is something relatable for students. I think that it is useful for students to start with the prime number chart as they are starting to grasp the topic so they can slowly become less reliant on referring back to it when working through finding factors.

    I love your viewon how to make teaching factors and multiples more fun and on how to make it understandable for your students. All students love food being incorporated into lessons so way to go with the goldfish project!! All of the ideas that are posted throughout are very useful for teaching a lesson. whether students are just using these as handouts or practice sheets, it is good for them to work through and see how they work with these numbers and finding factors
