Summary: Algebra is a multi-dimensional content of school mathematics. In this study a fine-grained analysis was made of two lessons on introduction of variables in two Swedish classes with teachers who followed the same curriculum. When comparing the two lessons subtle differences were found in the approach to algebra and the meaning of variable in what at first seemed to be lessons about the same content. Findings indicate that teachers shape the opportunities of learning by the approach they take.
