I wrote a blog post 2 years ago about using the cake method to find the GCF & LCM of 2 numbers. (I absolutely LOVE this method and my students have had alot of success with it!) I have been meaning to follow up on that post by sharing how to use this method for moreRead more about Finding the GCF & LCM of 3 or More Numbers using the Cake Method[...]
Included is a cheat sheet for least common multiple and greatest common factor (LCM & GCF). There are 2 versions: (1) Fill in and (2) Already filled in. This works great as a cheat sheet and can be used as a handheld study guide or glued into interactive notebooks. You can also laminate the cheat sheets and use them year after year! The cheat sheet includes the definitions for LCM & GCF. Students will perform 3 problems for LCM and 3 problems for GCF. Want to make it a poster? Get it printed as a poster and laminate it!
Do your students struggle with the difference between LCM & GCF? Look no further than here! Print out as an anchor chart, or print smaller for student notebooks. The steps to finding both LCM & GCF will help students towards mastery.
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

It's Five for Friday on a Saturday!! :) Time to link up with Kacey from Doodle Bugs Teaching. :) This week we finally got to teaching GCF/LCM within word problems. The students theoretically learned GCF/LCM in 4th grade, but applying it to word problems was a challenge. We started off by reviewing LCM/GCF. I shared with the students how I DISLIKE factor rainbows. In my opinion they are not as easy to use as a table, so that is why I taught them to make a table if the numbers are smaller. However, for the larger numbers I would like them to use prime factorization to help them: I also made a LCM anchor chart, but I made a mistake on it, and had to scribble it out, so it wasn't picture-worthy. :) We then played Showdown with my GCF/ LCM word problems for older students. They had to identify whether the problem was a LCM problem or a GCF one. This was really good practice, because it is a hard concept for them to pick up on. You can find my GCF/LCM task cards HERE. I also created this to reinforce what we were doing for my fall line-up in my classroom: On Friday my teammate and I as part of our Fun Friday Enrichment time for the students who have not struck out with our behavior system got to participate in the Save Fred Challenge!!! I found a great resource on TPT from Smart Chick Teaching Resources. It was great! I gave my homeroom either a diamond or club suited card, and my partner gave his homeroom a heart or spade. We then split the kids up. I sent all the black suited cards to his room, and he sent all of the red suited cards to my room. The students then partnered with the student who had the matching number and color of the other ones card. It was a GREAT way to have the students mix and mingle! :) If you have never done this activity before--it's GREAT!!!!! They had a ball! This week over on Facebook, my fellow NC teachers and I are participating in a blog hop!! There is something for ALL grade levels to be had!! FOR FREE!!! Here are all of the starting points for each grade level: PK-2 https://www.facebook.com/MyKindergardenBlooms 3-5 https://www.facebook.com/mrelementarymath?ref=bookmarks 6-8 https://www.facebook.com/NorthCarolinaHistoryGal My freebie is a great one for older students to practice reflecting points over the y-axis to create a picture! Snag it on my FB page and be sure to check out all of the other freebies available!!! :) Also, in the spirit of fall and Halloween, this week I will be participating in a Halloween themed giveaway contest with The Teaching 2 Step: I will be giving away this product: The contest starts next week, so be sure to head on over for your chance to win!! :) This week as a whole again was great. I am still very much enjoying my decision to be in middle school...LOVE IT actually. :) At the end of October we are having a "Scare the Bear" costume/dance party during the school day. My teaching partner and I want to dress up as something that goes together, but we are struggling with an idea, so if any of you all have an idea out there, let me know, please!!! :)
