Number & Algebra Properties of Numbers
My Goal:
Identify and describe properties of prime, composite, square and triangular numbers
 understanding that some numbers have special properties and that these properties can be used to solve problems
 representing composite numbers as a product of their prime factors and using this form to simplify calculations by cancelling common primes
 understanding that if a number is divisible by a composite number then it is also divisible by the prime factors of that number (for example 216 is divisible by 8 because the number represented by the last three digits is divisible by 8, and hence 216 is also divisible by 2 and 4)
Prime or Composite

Lyrics: Some numbers are alone, they sit up on a shelf. Nothing divides into them but 1 and themselves. Other numbers have lots of fun and friends they have aplenty. Like 2 x 3 is 6, and 5 x 4 is 20. Some numbers just stand alone. And others you divide, numbers are composite or prime.
