Children can learn the Qur'an online at HomeQuran.com, LearnQuranKids.com and KidsQuranReading.com. One benefit of learning the Qur'an online is that children don't need transportation to and from a mosque or other teaching center, making it highly accessible.
HomeQuran.com is aimed at teaching the Qur'an to children as young as 4 years old. The program also includes lectures designed to teach young children about prayer, fasting, the prophet and other aspects of Islam.
Another online source to teach the Qur'an to children is Learn-Quran-Kids.com. This website offers one-on-one classes on the Qur'an with a focus on Tajweed, using Skype technology.
KidsQuranReading.com is another resource for children who want to learn the Qur'an. This institution focuses on children who live abroad with little access to traditional studies at mosques or other institutions.
