Using a hundred square and the simple trick of identifying numbers that are in different times tables, they were able to identify which numbers from 1-100 can only be divided by the number one and itself thus making them a prime number. Well done year 6. You took on a tricky investigation and solved it.
The "sieve of who"? Our year 6 pupils asked the same question during our maths lesson on Friday. However, by the end of the lesson everyone of the class could tell you who he was. Eratosthenes was an astronomer and mathematician who worked at the library in Alexandria, Egypt in 250 B.C. As the class discovered, he found a pattern to work out prime numbers.
