The first page contains all 26 letters of the alphabet for students to match wooden alphabet blocks to. The second and third pages are challenge sheets where the children can fill in the alphabet but there are missing letters! Print and laminate on card stock. I have found that the Melissa and Doug alphabet blocks are the perfect size. If you use the larger ones from Walmart of others places..the don't fit on the mat. However, if these are the ones that you have, you could always have the students create the picture to the side on the table with the blocks. This works great for an ABC center or for when students get finished with their work quickly!
