As I mentioned earlier this week, ED is working on the concept of odds-evens and is practicing skip counting by 2s. I printed out some mazes for her to practice counting from 2 to 200. There is a huge selection of mazes over at Print Activities with different themes (such as baseball, pirates, Thanksgiving, etc. etc.).
You can also find mazes to practice
