This site has some wonderful games for kids learning Hebrew; Hang Man in Hebrew, Trivia quizes, a word search in Hebrew (covering lots of easy vocabulary for kids). http://www.j.co.il – make a point to try the word search in Hebrew. Its very cool.
There’s a songbook that let’s you print some popular songs and prayers – the words in Hebrew. Some songs are secular Israeli, others are holiday oriented. http://www.j.co.il/songs/index.asp
There’s a fun application too that let’s you create a banner in Hebrew and allows you to use a variety of nice Hebrew fonts. http://www.j.co.il/signmaker/index.asp
