This week we will review the definitions of the following terms:
- Integers: Positive and negative whole numbers (not decimals or fractions)
- Factors: Numbers that can be divided into a larger number with no remainder.
- Multiples: The resulting number of multiplying two smaller numbers.
- Square numbers: When result when you multiply a number by itself (eg. 3 x 3 = 9)
- Prime numbers: Numerals with only two factors – one and themselves.
Resources:
- Erastothene’s Sieve – for finding prime and composite numbers
- How many factors can you find? (ABC Splash Game) – Easy
- Arrays – meet the factor families (ABC Splash Game)
- Adam Spencer loves prime numbers (ABC Splash)
- Patterns, primes and pascal’s triangle (ABC Splash)
Please write ten examples of each of the terms listed above. Use the following numbers to create a ‘factor tree”: 24; 120; 128; 130; 240; 360; 480.
We will practise our multiplication tables and learn more about prime numbers using the game “Multo”.
