I decided to start islamic studies with my son this Ramadan. I chose this textbook to start our lessons. The book is written in english, and there are three units with three lessons in each one. The lessons are easy and straightforward, as the illustrations and the activities. The recommended age is 5-8. I think when using textbooks you need to have activities, books, and printables to support your lessons. I bought my copy from @mumzworld.
