Erasing Letters 👉🏻 ages 3-5 👈🏻 Here’s a simple way to practice letter recognition and writing. Simply write the letters on a dry erase board using dry erase markers and ask the child to erase the letters by drawing over them with their finger. I also asked Oliver to name the letters as he was tracing them. This method would work perfectly for numbers and shapes as well! 👍🏻
