WebGreek philosopher and mathematician, Eratosthenes, created a method for finding prime numbers using a hundreds chart. Learners will discover the history of Eratosthenes, as well as the step-by-step method of finding prime numbers up to 100. A recording sheet is given to reinforce and practice, finding the first 25 prime numbers. WebThe Sieve of Eratosthenes is a simple way to find all the prime numbers up to some number n : Write all the numbers from 2 up to n onto a piece of paper, in order. We will perform the following steps so that all the non-prime numbers will be crossed out, and what's left will be the primes. Choose the first, i.e. the smallest available number.
