Common Core State Standards: K.CC.1, 1.NBT.1
This is not just for 100-Day. I've included 4 different center suns so that you can simply use this as a counting to 100 or 120 activity.
I've also made the "counting by 5's numbers in blue, and the counting by 10's numbers in red, so that students can easily count to 100 this way as well.
After which time, it will be updated and put in my TpT shop.
