Salt Painting Sensory Bin

_______

This gigantic salt painting sensory tray is inspired by the many eye-catching salt trays I’ve seen online over the years. In this activity, children are invited to color salt in a huge sensory tray and draw, design, and sculpt with the wet salt.

Salt is inexpensive and has a sand-like texture. It is taste-safe, non-perishable, and easy to color in many beautiful hues.

_______

tablespoons
toothed scraping tools

_______

Setting Up the Salt Painting Sensory Tray

This low-cost sensory activity is effortless to set up and works splendidly indoors or outdoors.

If doing the activity indoors, set a large, low-edged sensory tray on a table or stand made for the tray. This light, transportable active world tray, also called a tuff tray, is up to the task. Outside, if a table isn’t available, it rests on four stackable stools or patio end tables. So easy!

Tip: Outside, I recommend placing the sensory tray away from plants and grass since salt harms them.

_______

Next, add food coloring in a few hues to paint pots filled with water. Thinned tempera paints also work fine. Add eye droppers to the pots.

_______

Then add bowls and tablespoons for scooping and mixing, and toothed scrapers for creating designs.

Lastly, pour three boxes of salt into the tray. Reserve one box to sprinkle in more doses of salt periodically to add interest to the sensory invitation as children are playing.

The salt tray is ready to explore.

Benefits of the Salt Painting Sensory Tray

Exploring a salt tray and mixing colors is a relaxing and satisfying science and sensory activity. Salt trays are also popular as prewriting invitations. Children experience a novel way to practice tracing and writing lines, letters, numbers, and shapes, using at least two of their senses. They develop eye-hand coordination and refine fine motor skills.
