My school district recently began using Houghton Mifflin Math Expressions in Kindergarten, first, and second grades. Math Mountains is one of the concepts used with students. My previous post on the Big Wig Sub Shop demonstrates this concept.
Another way for teachers to create Math Mountains on the computer is with PowerPoint SmartArt Graphics. If you've read my blog for a while you know I love these!
Note: You will need PowerPoint 2008 or newer to use/create SmartArt Graphics.
I have included my PowerPoint file. Just download, open, and alter it to meet your needs.
