The book will be paperback, A4 sized (8.27 x 11.69 inches), and 150 pages in length.
PLEASE stick to the measurements in the cover dimensions image I have uploaded - they have come from Amazon KDP's own cover calculator.
The cover needs to look professional, pleasing to the eye and easy to understand, but not too intimidating, so that it appeals to both the teenagers who will mostly be using it, and the parents / organisations who will purchase it.
The cover might be enhanced by some original background pattern, or mathematical imagery. You may incorporate some of the mathematical diagrams I have uploaded into the cover, but ONLY if it makes the cover pleasing to the eye. A well-designed original pattern might be more attractive.
It would be great to see some designs with a beautiful pattern, and some designs incorporating some of my images.
I don't yet have a winning design in mind, so there's still time to think about new concepts for the cover.
Something clever with the layout of the title;
Interesting original patterns;
Something fun and light-hearted (but still looks professional);
Anything else you can think of that would make a great cover.
