Do you remember pattern block from kindergarten? I always LOVED them, so a few years ago I splurged and bought some nice wood ones from Lakeshore. Then when I was at my sister in laws house she pulled out cool pattern block picture cards for the kids to use, they were really neat. So I went home and looked into buying some, they were a little pricey so I did an Internet search and found a cool mom who had made her own (sorry I have lost the link) to print out of free. I laminated them and they have been great! I have them saved on my computer so if you want them just email me and I'll send them as an attachment!
