My class LOVED playing with the vegetable trays I purchased. It was wonderful the way they worked together as they loaded in the small, fuzzy balls into the trays. With 10 early 3 year old it was much, much easier to use small balls instead of a rice and noodles mix. The four year olds really enjoyed the rice mixture and the sensory aspect. Everyone had a great time. Awandco is great to get trays to be quickly and the wide variety allows lots of different play. The small trays are my favorite with all the different styles many children can play at once and I don’t break the bank!
