Even parents who did not, themselves, receive a Torah education growing up can provide a Torah education for their children. Suggested religious-studies curricula can be found through Torah Umesorah and Chabad. One can purchase textbooks and workbooks through such resources as Torah Umesorah publishing, bookstores, and other sources that can be found online. Some families hire tutor-rebbes (rabbi-teachers), others send their children to school for religious studies only.
If we educate our children according to their individual ways, as King Solomon admonishes us, we will help to nurture and strengthen their inner flames. Only then can we ensure the continuation of the Jewish people as a light unto the nations.
