Students use the "M" method when finding the LCM!
Each year my 5th grade students always confused Least Common Multiple and Greatest Common Factor. In an effort to help them keep the two straight, I try to make the way I present one very different from the way I present the other.
For LCM, I use what I call 'The M Method'. Using a large M as a visual greatly helps my students distinguish between LCM and GCF. I created this pack to introduce the method to my students.
The pack includes a LCM matchbook fold-up. A poster, a half sheet copy of the poster for a student resource and a two page worksheet.
This pack INCLUDES the Least Common Multiple Poster, which is listed separately in my shop. If you buy this, there is no need to purchase the visual.
To learn how to print a poster visit my Making Posters blog post.
When assembling the matchbook fold-up, run a two-sided copy--the front cover (upside down intentionally for easier copying) and the inside. With the inside facing you, bring the top of the paper down to the bottom horizontal line and fold. Then bring the bottom of the paper up and fold on the bottom horizontal line. The result will look like a giant matchbook.
