Extra Credit 1

"When a child their 5th year he or she is given 5 buckets of different colored paint and a canvas."

First of all, there is a grammatical error. There is no verb in the first part of the sentence. Also, 5 should be written as "five" because it's under ten. Just saying "their 5th year" could mean anything. It could mean their fifth year in school, in life, or even their fifth year of doing a hobby. I interpreted it as being their fifth year of life. 

I would say:

"When a child has reached the 5th year of his or her life, he or she is given five buckets of different colored paint and a canvas."

or simply:

"When a child as turned five years old, he or she is given five buckets of different colored paint and a canvas."
