One of my favorite homeschooling blogs Confessions of a Homeschooler posted about a great website Prekinders with free pattern block mats to use with pattern blocks. You can print them in color or black and white and laminate them. I chose to do b&w to make it more of a challenge. They are so cute, I had to print every pattern. Great workbox activity!

I'd correct her, but it's just so cute how she says it.
