This site sells storybooks, CDs and more for parents and teachers to use to teach children Ivrit. I don’t know much about the materials themselves though I support anyone claiming that their materials make learning Hebrew fun and Exciting.

They have a great activity page with downloadable pages for free – I really liked the color by letter. My 4 yr old enjoyed it a lot.
