For the last couple of years my children have taken part in the summer reading challenge at the local library and one of the incentives for doing so is a free bookmark. This year it is about a quest to find the golden book and the bookmark shows some of the characters that are being used to encourage the children to read.
The challenge works by getting the kids to read six books and for each two they receive stickers and rewards like pens and cards. At the end they receive a certificate that always makes them proud of having made the effort.
