As a starter students highlight what they think the important information is on the handout (which has been differentiated). Students then use what they have done to come up with some questions and answers that they will use to test the person sitting next to them. After they've come up with the questions, they quiz each other. Then, as the last main activity, students write a paragraph explaining the key features of the Battle of Britian. Plenary is a Think/Pair/Share exercise.
