It is so important that our preschoolers practice writing with lots of different materials and utensils. They found these salt trays to be irresistible.
To set up the center, we placed a set of alphabet flash cards (as a model) next to shallow trays of salt. The students could choose to use a paint brush or a popsicle stick to write.
The sound and feel of the salt on the trays is fun, so in addition to writing letters, we had a few friends draw other pictures and spend time touching it.
The other thing that I like about these salt trays is that they are very easy to clear. I took a quick video to show you how it works:
Have fun playing and learning with your children today!
