Oh.My.Goodness! This is one of the BEST hiragana-learning websites for children I have ever seen!!!
This hiragana-learning website, Aiuebu/あいうえぶ (by S5-Style) has been designed for children ages 3 and up. The purpose of the site is to provide children with a fun and cute way to practice reading and writing their hiragana. I have to say… it sure is cute! I think it would only be better if it would pronounce each kana and word for you when you click on it. It looks like they are adding more words daily.
