I would love to do this with the book The Dot as a collaborative art project!
Challenge display in my class. Over the week coloured lolly sticks are placed in different areas. When children complete a challenge/task they put a stick in their pot of gold.
Great for phonics or numicon - basically any topic where you want to put a clue on the outside and answer inside. Could even put different textures/colours or smells inside to discover in a sensory area.
This would be a great activity for center time because it works on sorting colors as well as counting!
Number formation display I think this is fabulous for engaging the boys. I would probably introduce one number at a time and slowly build it up.
Cool idea for a block station to show them what they can build and to post pics of cool things they or other students have built!!!
