We used the song 5 Little Pumpkins Sitting on a Gate as our stimulus. As a class we discussed the different construction materials we have in our class. We decided which materials we thought would be the best and began to construct our own gates. We challenged children to make a gate that would hold one pumpkin (we used orange ping pong balls for pumpkins) Once children had made a gate that would hold one pumpkin we challenged them to make them bigger to hold up to 5 pumpkins. We had to think hard about how we could change our structures to make them hold the pumpkins without rolling away.
