These projects were formatted for 30 minutes of child participation with some prep by the teacher and some by the child, depending on the age of the child. But they can certainly be done at home. I did projects in 3 temples. They all needed me to keep the cost down. These projects are economical because they had to be. I wanted Jewish kids to understand the incredible depth and beauty of their religion. I wanted to teach Judaism through crafts. Children remember hands on. I went to a bat mitzvah at Temple B'Nai Israel in Galveston years after I had left. Kids surrounded me that had done projects years before, and described their delight in doing a project that I didn't even put in the book, a project involving adding headdress, necklace, bracelets, ear rings and nose rings to Moses' Egyptian adoptive mother. I had forgotten all about it. They never will.
