Designs and patterns, music and fractions…and mathematics

Quilt pattern
Have a look at the quilt and try to identify the details of the pattern.
Given that this kind of quilt does not have to be stitched one square at a time, think of an efficient way of making it.
Objectives
To appreciate the richness of the links between mathematics and arts
To experience relevant activities and reflect on how they might be adapted and extended for use in the classroom
To explore relevant websites

Maths everywhere – from the graph paper websiteCalculating various bits about regular hexagons
Given length of a side x... Tip to tip across the hex is 2x. Height of the hex flat side to flat side is 2x(sqrt(3/4)) or about 1.732x. Area of the hex is 1.5(x^2 (sqrt(3)) or about 2.56x^2.
Example: Making graph paper with 4 hexes per square inch
Hexagon with a side length of x... The area of that hex would be about...2.6 (x^2)So for 4 hexes per square inch...4 * 2.6 (x^2) = 1x^2 = 1/10.4x^2 = .096x = .31 inches per side.
Extra: 1 sq. in. per hex ~= 0.6204
