This article describes a classroom episode where a student’s unanticipated reasoning reminds us that foregrounding student sensemaking requires more than listening for strategies from a prepared list.

I present how transformations can be applied to support students’ solving linear inequalities involving absolute value. In particular, the horizontal dilations/compressions and translations of graphical representations of distances from zero along a number line are important tools to emphasize a visual representation of the solutions to absolute value inequalities.
