What better way to celebrate 100th Day than with some collaborative building?! Preschoolers love stacking and tower building so why not capitalize on their interests with one of these fun center ideas...

April over at suggests setting out 100 different items on a table - foam blocks, Legos, plastic animals, wooden blocks, etc. - and inviting your kiddos to work together in order to create something. You'll be amazed at what your creative preschoolers will come up with! Castles, zoos, and towers - oh my!

Keeping it more uniform {while also allowing for creativity}, Melissa of invited her students to create a structure from 100 drinking cups. Tall. Short. Narrow. Spread out. Who knew there were so many variations to be had with simple drinking cups?!

Last, but not least, while this activity wasn't originally intended as a 100th Day activity, we think it would offer a great tabletop building exercise for your celebration. Kristina over at cut generic kitchen sponges into strips and invited her kiddos to use them to build towers. Set out 100 of these sponge pieces and it will be interesting to see how creative your kiddos get as they build! [NOTE: These are especially great for tower making, they take up little space, and would be easy to use again!]
