日本語の中の漢字

I am not sure if it can help or not, but I have created a series of lessons (web pages) that teach you the first 150 Kanji in Japanese with native speaker pronunciation demonstration.

Why don't you take a look yourself?

http://www.japanese-language.aiyori.org/kanji-numbers.html

It is the index page for Kanji related to numbers. Click and learn. Or you may select other Kanji from the navigation bar on the left.

先把单个的字的发音掌握了，然后往上拼就行了。碰到特殊的再特别记忆~
