Play on numbers...

Trev has been teaching Parker rather advanced math for a 4 year old (somebody's gotta do it so it might as well be the guy with the math degree). They started with counting by two's which Parker mastered in an impressive 5 minutes. They then started with counting by 10's which Parker almost instinctively knew without any help. He easily did "fifty", "sixty", "seventy", "eighty", "ninety" and then he goes... "tendy" for 100...which even though, incorrect, we both thought was pretty ingenious for a 4 year old.
