As a mentor, I try to make activities quite personal which does tend to hold the concentration better.
This worksheet works really well.
Read the unicorn story twice, answer the questions and then answer the other set of questions which is personal choice. i.e. What are you going to name the unicorn? and How old is the unicorn?
These are questions with no answers in the story so it allows the children to think on their own and write their answer.
