In this paper, we deal with the teaching of algebra in the elementary school mathematics, and call this algebra teaching method as 'early algebra'. Early algebra is appeared in the 1980's with the discussion of 'algebraic thinking'. And many studies about early algebra is in progress since 1990's. These studies aims at reducing difficulties in the teaching of algebra and the development of algebra curriculum. We investigate the background of early algebra, and justify teaching of early algebra. Also we examine the projects and studies in progress around the world. Finally through these discussions, we compare our elementary textbooks with early algebra, and verify the characters of early algebra from our arithmetic curriculum.
