We are very aware that lots of our children have their own interests for example animals, aeroplanes, super heroes, Lego etc. Children are much more eager to write when it is something they are interested in.
If you are finding it difficult to keep your child engaged and on task then use the learning challenges that the teachers have set for their year group, but change the subject area.
For example, Edinburgh Zoo are showing live web cams of their animals. The children can log in and then write about what they've learnt. A leaflet, PowerPoint or information book can be created on whatever they are keen on.
