Not my idea but a wonderful Tuff Spot activity
Shaving foam and powder paint mixing and mark making
Placing marbles on an upturned bath mat - rockmyclassroom.com
Colour/pattern Sensory tray - Elmer Again - could add shape tiles to rainbow rice/ rainbow pasta
ice cream play doh
Quiet activity! Pick up pom poms with chopsticks - number cards could relate to number or colour - endless possibilities.....
Fine motor skills reinforcement with leaves.
Toppings for the play dough pizza (",)
hair gel, food coloring, glitter - my kids LOVE these! Make sure you put tape or something over the zipper side of the bag! We had problems with leaking after they were played with for a while. :)
