The 'small catechism'. This page has been originally conceived for catechists and religion teachers, but it is also open to children as it includes DIY.
"Hi, If you want to learn more about my friend Jesus, you are at the right place! Are you a teacher or you are a child who wants to make his first communion? If you download this free brochure and these DIY, you have a funny little course on the Eucharist. Easy and interesting, it has been made for children."
