Prime and Composite Numbers Assessment

The video tutorial explores the concept of prime and composite numbers, focusing on the fifth-grade standard 5.4a in Texas. It uses a problem from the 2017 STAAR test to illustrate the differences between prime and composite numbers. The video explains that prime numbers have only two factors, one and itself, while composite numbers have more than two factors. The number two is analyzed to determine if it is prime or composite, concluding that it is prime despite being even. The video also discusses the misconception that all even numbers are composite, highlighting that two is an exception.
