Roald Dahl's, Matilda the Musical - Toronto 2016...it is going to be quite the show!
Theatrical productions such as these can be an amazing experience, see them as windows of opportunity for learning.
For example, if the play is based on a novel take the time prior to screening to introduce the story and author, read the book together.
After you've seen the play encourage ongoing discussion, did the production portray the novel in its entirety? What did they like most about it? Who was their favourite character and their least favourite?
Children WILL learn through their own experiences.
