| Research Abstract |
This research has developed teaching unit and leaning method centered in mathematical activity on spiral curriculum about school algebra. Teaching unit in this research forcus on square root,expression and proof, sequence,limit of sequence,the volume and surface area of square. Through these lessons about teaching unit, students make progress to form conception of irrational number, to make connection between unit such as number, expression and proof, sequence, and to reflect own learning about secondary school algebra.
