Page of the children's book on mathematics (by cover)

She has made more than 10 variations of a page for a children's book on mathematics. The book contains more than 200 pages. Deadlines for inventory less than 5 hours). I think the pages need to be combined - not all 200 pages can be made together. It’s boring, and that’s the same book first.

What was done?
Different backgrounds, fonts (both size and appearance), small graphics and/or illustrations.
