The last theme we did at the end of the school year was transportation. we did incorporate building blocks in our play and also sand, rock, and sticks. But, I do believe if we had added flashlights it would have made a world of difference. I would have loved to see what they would have came up with. Especially when they were playing outside. I have a garden that wraps around my deck and they drove through the hostas. The deck is low to the ground so it is very dark underneath, it would have been great to see how they would have incorporated the light and shadows from under there into their transportation play! I will definitely add those to the shelves so they are easily accessible.
