Enormous 100s Chart

Today we created a huge 100s chart on our classroom floor (yes, dry erase markers come off of tile).  Students noticed:
You count by ones if you go across.
You count by 10s if you go down or up.
You can count forwards or backwards.
You can start at any number and count by ten.
If you go up and down you can see that the same number repeats itself.

We made a plan, moved furniture, worked together, made a mess, learned a ton and had a blast!
