Below are several PDF files. Each one has a list of where each individual juz (parts) of the Quran start and stop. All of the files are nicely decorated except the one that says ‘blank’ and the ‘blank small’ one.
Print and use coloring pencils, markers, or crayons to add color. Or print of decorated printer paper.
This is a good activity to do with children. The artist-types can get very creative with the blank one.
