Good pictures and explanation in the Halloween PPT but pretty advanced for my elem. students. Props to the OP.
But if anyone wants to use this PPT in class please make sure you correct all of the sentences like "Children who would visit the houses in their neighborhood and food, and money. " and "America the Irish found that pumpkins. Jack O Lanterns were made to keep the bad spirits away. " Perhaps the OP can double-check their sentences and re-post it.
The shadow puppet PPT's step-by-step explanation helped me to understand the activity. If I end up using this idea, I will touch up this PPT with some pictures of each step and correcting the few grammar mistakes. Thanks OP.
