Kindergarten and 1st Grade students dressed up on the 100th day of school as 100-year-old versions of themselves. Students also showed 100 by counting collections of objects by 2s, 5s, and 10s, or building. Creative ideas included 100 eyes on 50 monsters, 100 beads glued on a 100-year-old door, 100 candles on 20 cupcakes, and 100 stars to “level 100” on Super Mario.
