I bought a cookie sheet at the dollar store and wanted to find a way to incorporate it to our preschool Tot tray weekly activities or "juegos" as my little one likes to call them. I once saw a printable on this blog that I thought my little one would enjoy. I decided to draw my own and hot glue some magnets to pom poms and, voila! We now have a fun activity to practice numbers and counting. The numbers we used are just made from old milk jug lids and I used a sharpie to write the numbers.
