Would highly recommend.
I have used these books both with low ability year 10 and also mixed ability year 7.
I have found they work well with both groups. I especially like the worked example which the students read which encourages more independent learning and engagement.
I think the books are attractively laid out and clear and easy for all abilities to follow without being patronising. The students are very happy to use these books.
I like the questions as they really get the students thinking and demonstrate to the students they can answer questions that at first look impossible if they just stop and think.
I like the detect, recall, solve route through questions and often use this when going through past paper questions.
To improve the books slightly I feel question 2 in each section could be made a little easier to boost confidence, maybe even with a little scaffolding to help answer this and then questions 3 and 4 getting progressively harder

I and the department are very impressed with the design and the specific feedback and intervention activities for students.
