PRIME PHYLLOTAXIS SPIRALS  “The phyllotaxis spiral is one of the classical forms of mathematics, and there is a wonderland of resources available online both images and explanations. The basic idea is to put points round in a spiral with the same angle between each point.   Note that, as the angle changes the dots sometimes pack in better than others, this can actually be studied and the best packing is related to the golden ratio.”    Check out the source. It’s a really neat article.

Following Learning: playground prime numbers

This week I wanted my Year 4 and 9 year-old) class to have a good idea of factors and primes. First, on Monday, we got the Cuisena.

The Ulam spiral is a simple method of visualizing the prime numbers that reveals the apparent tendency of certain quadratic polynomials to generate unusually large numbers of primes.

Found this Braille style picture of the Ulam Spiral: “ When arranging the natural numbers in a spiral and emphasizing the prime numbers, an intriguing and not fully explained pattern is observed,.
