I love to work through SATs papers are part of my revision program. These two PowerPoints are designed for whole class interaction. All the students need are some whiteboards. Each question is immediately followed by its answer.
This has lots of motivational and organisational benefits. The first is the students get immediate feedback on their ideas and misconceptions, without needing to wait until the end of a test. It also means different students can explain each of their solving strategies to the class and help everyone become more effective learners.
As the answers are straight after the questions, it is possible to simply use these PowerPoints for 5 minutes a day and still get the full benefit as all the questions are immediately solved. This is also a nice way of tutoring students at home. The tutor can then focus on the areas the students to need to work harder in.
