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
Find the Letter & Swat It! Active Way for Learning Letters!
Draw a letter on a pin board and have children push the pins in correct order to form the letters. (Could write numbers and even draw arrows to show letter formation sequence.) Great for fine motor skill development and letter formation and recognition
My daughter is too old for the letter matching task, but love the idea of the clothes-pins. Going to make more complicated, teen-friendly game and use the clothes-pin instead. They would be great for her fine-motor skills and hand strength.
