About the same time I decided against adding a sensory table to our in-the-works-future homeschooling room, Matthew fell in love with the one at the distance school where Caley has her science classes.
He simply couldn't bear to leave the amazing, precious beans in a bin. So he and I concocted a plan. We drove to the nearest grocery store where he filled a mini shopping cart with bagged beans of his choosing.
When we got home I initially put them in a Rubbermaid container but that was cramped and too deep and just no fun. Fortunately, the train table has a raised edge so it works great (mostly) to keep the beans contained.
Voila! $15 sensory table.
The best part was, they played peacefully for hours and so far only one handful of beans has been thrown into the face of a sibling during a tantrum.
