What is the ruling on placing pictures of animated drawings of girls, faces, and animals in worksheets prepared for female students in school, with the aim of beautifying the paper and making the students love the subject?

The basic principle concerning images of animate beings is prohibition. We are commanded to efface them, not to hang them. Beautifying the paper is not a legitimate Sharia justification for hanging pictures. Students can be encouraged through other permissible methods, such as decorating papers with natural landscapes or distributing gifts.
