TIGER, tiger, burning bright
In the forests of the night,
What immortal hand or eye
Could frame thy fearful symmetry?
Nature is full of symmetry. Bring something into the class room that shows the symmetry of nature (like a leaf or flower). Secondly, use squared paper, colour in to make a pattern using one line of symmetry (half of the page). Then try folding and cutting paper and discuss the lines of symmetry in the patterns produced.
SHIVA Charity (UK) puts these free educational pages on its web site in order to be used primarily in Nepal, and Sri Lanka, where lessons are mostly repetitive "chalk and talk" and curriculum restrained. We are involved in teachers' resources training there, and hope that schools in the UK and elsewhere will support SHIVA Charity's cause with funding. Please visit our main pages to see the work we do, and how we raise money for individual projects and for child sponsorship.
