Reading in mathematics classrooms needs to be an active part of the learning process. If it continues to be viewed as a passive way to gain information, then its benefit to the learning process will also continue to be under-utilised. The "Read--Think--Do (x2)" model, designed by these authors and described in this article, can be a support to students to become more active readers. However, teachers need to show students how to make use of the model and to encourage them to do so. By having the model on a wall in the classroom, teachers can be reminded to ask questions as their students are reading. Changing students' reading habits will need constant reinforcement and will not occur quickly. (Contains 3 figures and 1 table.)
