Greeting Ihsanpedia Friends! Welcome to this informative article where we will explore the topic of finding the Greatest Common Factor (GCF). Whether you are a student studying math or simply someone interested in expanding your knowledge, understanding how to find the GCF is essential. In this article, we will delve into the step-by-step process of
How do you teach students to find greatest common factors and least common multiples? Do you have them create prime factor trees or use the ladder method? In this post are a couple visual supports for students learning to find GCF and LCM as well as a few engaging practice activities. I go back and forth on which method I like better for finding GCF and LCM. Sometimes I think the ladder method (or upside down birthday cake method) is the best and other times I just really like making prime factor trees. There's something really cool about every number breaking down to its own, unique string of prime numbers. Prime factoring word wall reference This word wall reference (part of my math resource library) supports students breaking numbers down into their prime factors through the example of prime factoring the number 60 into 2 2 3 5. The ladder method for finding GCF and LCM Then there's the ladder method. Some also call this the birthday cake method. I especially like this method for finding LCM because the numbers line up so nicely. One warning though: this method doesn't work so great with 3 numbers. A workaround when working with 3 numbers is to find LCM and GCF of 2 of the numbers, then use the result to find GCF/LCM with the 3rd number. The reference above is also part of my math resource library. It's also part of my 6th grade math word wall. 6th grade math word wall - GCF and LCM A teacher asked if I could also add references for finding GCF and LCM the traditional way to the 6th grade math word wall. I used the same numbers as the ladder method so that students could compare the two methods and decide which they like better. Activities for teaching GCF and LCM: GCF and LCM solve 'n check task cards Even in print form, these GCF & LCM solve 'n check task cards are self-checking. They also come digital in Google Forms (linked in the same file). Students answer both questions on a card then use the check number in the lower right corner to see if their answer is correct. Solve 'n check tasks can be given to students for practice in groups or individually or even used as an informal assessment. I used to like using task cards to assess students because they didn't cause students as much anxiety as quizzes. Lower student anxiety meant I could really see what they knew. GCF, LCM and prime factors math pennant Students find greatest common factor, least common multiple and prime factorize in this GCF LCM math pennant activity that doubles as math classroom décor. Here I took a photo of the same pennant colored differently and where different methods were used to find GCF. Students can complete their pennants then decorate them with a little color. The end result makes for a nice classroom display of what students have learned. GCF and LCM digital math escape room Here's puzzle #4 of a GCF and LCM digital math escape room. Students must unlock 5 locks by finding either the greatest common factor or the least common multiple of 20 number pairs. Questions are grouped 4 per puzzle, resulting in five 4-letter codes that will unlock all 5 locks. The entire self-checking escape room is housed in one Google Form with no outside links, making it a breeze to assign. If finding both LCM and GCF is too much for your students, there's also a GCF Only digital math escape room here. There are more ideas for teaching GCF and LCM, including a video explaining the ladder method, in this GCF & LCM post. More posts: Activities for Teaching Unit Rate Middle School Math Word Wall Ideas

GCF Snatch is a 2-player game that allows the students to practice finding Greatest Common Factors for a pair of numbers. Each player rolls two dice to create an ordered pair that is used to select a box on the game board and places a colored counter on it. The players then find the GCF for the numbers in the selected boxes. The player with the larger GCF keeps his colored counter on the box while the other player removes his. The first player to get four boxes in a row on the game board - horizontally, vertically, or diagonally - wins the game. An answer key is included. This activity meets or exceeds the Common Core Standards of Mathematics and makes for a great class activity or math center. This game is also part of Math Games BUNDLE - Grade 6
