### Rock on Mathematics

December10

This Tessellated Pavement in Tasmania, Australia, formed by rocks that have fractured into polygonal blocks that appear tiled or tessellated. The overall flatness of the pavement is due to wave and chemical erosion. Then rocks which have absorbed salt water at high tide dry out at low tide. This causes salt crystals to grow and […]

### Create your own fish tessellation

August21

Tessellations are wonderful ways to create amazing patterns. The one above is based on squares and can be done with careful attention to detail. This is a great activity when studying different shapes in Junior Mathematics and, if using card, gives a practical take-home product ready to hang on display. Instructions are here. Also see […]

### Tiles and Tessellation Art Exhibition

January30

The art of fitting together mathematical shapes in repeating patterns is the basis of many fine designs and art work (unlike this one): In 2012 there was an excellent exhibition of mathematical art works. Click on this image below (“hyperbolic tiling”) to find out about these wonderful works and their author-artists: (Footnote: the first pic […]

### Tessellations – Pt II – Cool interactive site

March7

The Escher blog leads to your own discovery about symmetry in Mathematics. We most often use symmetry in our study of Polygons (from the Greek language where “poly” = many and “gon” = angle or ‘knee’). Actually, I must confess that I find it easier to think of a polygon as “many-sides” for a more […]

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
