Prime Number Challenge
Today we were set a challenge to find all the prime numbers between 1-100! Click to find out more.
Prime numbers only have 2 factors: 1 and themselves. We were given a 100 square to go through all the times tables and colour in the composite numbers (numbers that aren't prime/have more than two factors). We then had to count how many prime numbers there are between 1 and 100. Ask us how many there are!
