In this paper, we deal with the teaching of the approaching to algebra based on patterns. The change of algebra curriculum has been undergoing in many countries including USA, England, Australia. The traditional algebra curriculum starts with letters(variables), algebraic expressions, and equations. But these formal approaching method has many difficulties in teaching school algebra. Therefore the new algebra curriculum has to be needed, and the approaching to algebra based on patterns has been focused. In this paper, we compare this new approaching to algebra based on patterns to the traditional algebra curriculum. Next we consider the NCTM algebra curriculums based on Standards (1989) and Standards 2000(2000), Britannica textbook series(1998) based on RME. Also we investigate our pattern approaching in our curriculum and discuss some problems from the perspective of the approaching to algebra based on patterns.
