I did this activity with my 2's today, they loved it and it filled the room with a lovely scent. Make sure to have them wear smocks as it is kind of a messy deal!
measuring cups, spoons, sifters, other baking utensils
some old spices, cake sprinkles, etc.
sensory table or dish pan
Pour the flour in the sensory table. Sprinkle in the spices, or have the kids do it. (you can even give them the spice containers, they have fun with those too! Give them the baking and measuring utensils and let them have fun baking and making their "supper pots" (as my 2-yr-old class put it!)
