Division terms, factors, primes - 4th grade

I explain the terms dividend, divisor, and quotient plus we practice those a little. Then we delve into the problems in division by zero. Instead of just announcing that "You cannot divide by zero", I explain WHY that is. Because of the problems, dividing by zero is "undefined". Lastly we look at zero divided by zero, and why that ends up being "undetermined"... essentially, there could be many possible answers that would work, so 0/0 is termed (by mathematicians) "undetermined".
