For Sura Ankabut, recommended to be recited in Laylatul Qadr…make handprint spiders with your little ones! More details on this website: http://islamfromthestart.blogspot.co.uk/2012/08/handprint-spider_93.html
Or how about this craft sent in by a mum? I love how her son chose to make it colourful, instead of black!
Here is another craft for slightly older children perhaps? They talked about the fragile web of the spider, and related it to this world…
