For World Book Day, we encourage the children and staff to come dressed as a fictional book character. In the past, we have had each class come to the front of the hall so everyone can see their costumes and a selected panel of staff members then choose 2 children to be winners for their costumes, getting a prize of a book. This year, we are again encouraging children to come dressed as book characters and will be having prizes for each class, but I was looking for other ideas to organise the assembly. I sometimes feel, with each class parading at the front of the hall, things drag on and especially the younger children get quite restless. Any suggestions that have worked for others?
