In this lesson, we will explore numbers with only two factors and define these as prime numbers. We will then play a game that involves making arrays and identifying prime numbers up to 20. Our independent task to conclude the lesson will require all prime numbers up to 100 to be identified by using a range of clues based on multiples and factors.
