Had when i worked in a preschool and kids love them! I would use colored sand instead of white salt. DIY salt tray with alphabet cards. Easy to make and kids have fun smoothing out the salt after correctly making the letter
Snowman activities: Children move the snowman's nose to whatever letter you want them to find. Great for an easy whole-group assessment. Includes faces for upper and lowercase letters, skip counting by and as well as numbers to FREE printables.
