Interactive Mathematics Miscellany and Puzzles
Since May 6, 1997You are visitor number E66B7E in base 20 Raymond Smullyan, a Mathematician, Philosopher and author of several outstanding books of logical puzzles, tells, in one of his books, a revealing story. A friend invited him for dinner. He told Smullyan that his teenage son was crazy about Smullyan's books and could not wait to meet him. The friend warned Smullyan not to mention that he is a Mathematician and that Logic is a part of Mathematics because the young fellow hated Mathematics. Having told this story, would it be wise to announce up front what this site is about? |Contact||Front page||Index||Store|

Mathematical Images: Symmetry I love finding ‘maths pictures’, and thought it would be nice to start collecting and sharing them. Symmetry is the easiest to begin with, unsurprisingly. Images with simple line symmetry can be great for young (i.e. Y7) pupils to engage with, allowing for discussions about strategies to ‘test’ to how symmetrical an image is and how it could be improved to be ‘more’ symmetrical (this is a good ‘way in’ to using squared paper to complete reflections). Rotational symmetry is fun to explore with an interactive whiteboard, and more practical activities abound (e.g. for homework pupils can draw their own Rangoli patterns, or make patterned wedges that can be repeated to build up a whole shape). Some of my most able Y7 pupils wrote excellent pieces discussing symmetry in buildings and gave their opinions on how symmetry affected the attractiveness of a building or shop display.
