This workbook is very comprehensive and can be used for 4-5-6 year olds easily. It has stories, coloring, games, cut-outs, stickers, songs, etc... wonderful! As a teacher of Islamic sunday school this book reduces the time making copies for coloring and worksheets. This has it all! I don't have to search around and make my own curriculum with worksheets. The only thing I want to know... where's the CD for the songs!?! It doesn't give the tunes for the songs so I am going to have to be creative to make up some tune for the songs in the book.... UGH!
