Year 6 - Number and Algebra

Standard 6.OA.1.1 - Practice identifying prime and composite numbers.

Included Skills:

Number and place value
• 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)
• Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers
- applying strategies already developed for solving problems involving small numbers to those involving large numbers
- applying a range of strategies to solve realistic problems and commenting on the efficiency of different strategies
• Investigate everyday situations that use integers. Locate and represent these numbers on a number line
- understanding that integers are...-3, -2, -1, 0, 1, 2, 3,.....
- solving everyday additive problems using a number line
- investigating everyday situations that use integers, such as temperatures
- using number lines to position and order integers around zero
