Subject: Magical number ten

I feel that if my students can grasp how magical and important the number 
ten is, they will be better in all their mathematics. I am looking for ways 
to show this to them, but I'm stumped. I know many adults do things such as 
think of the number facts for ten when adding and subtracting other 
numbers, then make adjustments in the problem. I hope you see where I'm 
going. I wonder what other things I can show the children about this 
important number our system is based on. Any ideas?
Thanks so much!
