100 Day Project Ideas: Poster Collections

What is important to remember if you’re planning a Family Project is to challenge your students and parents to try to use what is lying around their house. Although 100 seems like a giant number to children, they’ll learn that within their home, they can definitely find 100 items!

The fun part of gathering up 100 items from their household is to turn it into art! Here are a few poster ideas for students:

q-tips
dots
candy hearts
Goldfish
stickers
fruit loops on a string
legos stacked up
Monster with 100 googly eyes
