I like that you've tried, however I have an 8yo (Y3 in UK, so 2nd grade US) and I don't think she would get it yet. She has just started simple devision while doing times tables. She hasn't covered the concept of remainders from devision, and has no concept of fractions. I could probably just about explain the concept of a Prime to her, but it's using concepts she hasn't learnt. She is also generally towards the top of her class for maths. My 4.5yo will have no chance, more interested in sharks, trains or even better shark trains!
