So, as one of my students and I were recently printing out a new copy of a 30 x 30 multiplication chart, we discovered this gem........... yes, it really is...... a LCM/CLD CHART!!
Also, in case you're wondering, there is a great set of multiplication charts that I use and will include them below (click on the image for the link to the image, or the website where possible).
Happy Printing!
