HaGefen Sabbath school material is a good Bible-based source for Sabbath school teachers. It is divided by ages: 3-6, 7-9, 10-12. Each age group has 5-6 series with 12 lessons in each. It includes teacher's guidebook and worksheets for children. The lessons are built step by step and fit to a class of 45 minutes up to one hour. The material has been used by many congregations in Israel throughout the years and now is in process of renewal and update. If your heart is into children's ministry in Israel, please consider supporting the project.
