Prime Time

Introduces the concept of prime numbers through an animated space story about creatures with from two to nine heads. Explains that prime numbers can be represented by arrays with no more than one row or one column and that composite numbers can be arranged by arrays with more than one row or column. Ends with the space cadet saying, "I wonder what the next prime number is after seven. Do the primes keep going, or do you run out of them?"
