Kenchako Daibouken - Kenchako's Great Adventure

Kenchako is a website for kids and Japanese to practice Japanese but it can be just as helpful to you! This link will take you to some PDF files of Kanji worksheets with answer keys included! These are also great for reading practice. If you're not familiar with written Japanese, it's OKAY! You should still be able to navigate the site fairly well by following this key:
小学 means elementary school
１生 (lowest level in Japan elementary school) means 1st year (student)
２年　means 2nd year (student)....
６年 (highester level in Japan elementary school) means 6th year (student)

Each colored box represents a different level.
