Critical thinking plays a significant role in mathematics. When faced with problems to solve mathematicians routinely make reasoned judgments about what, and how to think. While thinking about mathematical concepts, procedures, strategies, tools, representations, and models, decisions are made through the use of criteria and appropriate evidence. To think like a mathematician is to think critically through the mathematical processes. By promoting, teaching and assessing critical thinking through the processes, teachers not only help students to learn to think like a mathematician, they ensure students think to learn about mathematics. By placing the quality of thinking at the core of learning mathematics teachers can make learning meaningful and engaging for both students and teachers. Come learn more about putting thinking at the core of the mathematics classroom.] Critical thinking plays a significant role in mathematics.
