  This paper is related to my ongoing research concerning the possibility to enhance teachers' algebraic thinking through the creation of a learning community consisting of three teachers and a researcher. It explores teachers' reflections when engaging in a mathematical task related to elementary algebra in collaboration with a researcher. Issues concerning the different steps in teachers' reflections, their use of symbolic notation and its relation to algebraic symbolism are addressed. Possible consequences for teacher education are also discussed.
