The dry bin is the one I reach for on a morning when I need twenty quiet minutes and I have not planned anything.
Everything lives in one lidded box: a batch of dyed rice, a bag of dry pasta, a jar of pom-poms. I tip one filler into a deep tray, add two scoops and a small bowl, and hide a few treasures in the bottom.
What surprised me is how much of it is not sensory at all. My 5 year old sorts by colour and counts out loud. My 3 year old pours from cup to cup for a very long time and calls it cooking.
One filler, three tools, and a towel underneath. That is the whole formula, and these six posts are just different versions of it.
Tip
Under three, skip small dry fillers or stay within arm's reach — dry rice and lentils are a choking risk. A wide, shallow tray spills far less than a deep bucket, and a plain white tray makes the colours pop.
