## Mathematical habits of mind

January 27, 2010 10 Comments

Learning mathematics is not just about knowing, understanding, and applying its concepts, principles and all the associated procedures. It’s not just even about acquiring the capacity to solve problem, to reason and to communicate. It is only when these capacities become part of students’ thinking habits that one can be said to be mathematically literate.

The test for example that solving problem is no longer just a skill but has become part of students thinking habit is when students are doing it without the teachers still having to ask “Can you explain why you solve it that way?” or “Can you do it another way?” Those should be automatic to students.

“A habit is any activity that is so well established that it occurs without thought on the part of the individual.”

Here’s is a list of important mathematical habits of mind that I believe every teacher should aim at in any mathematics lesson.

Habit #1: Searching for Patterns

Students should develop the habit of

- generating cases and generalizing patterns
- looking-out for short-cuts that arise from patterns in calculations
- investigating special cases, extreme cases from patterns observed

Habit #2: Reasoning

Students should develop the habit of

- explaining the positions they take
- providing mathematical evidence/justification for the conjectures or generalizations they make
- testing conjectures by generating cases both special and extreme
- justifying why a generalization will work for all cases or for some cases only

Habit #3: Solving and posing problems

Students should develop the habit of

- always looking for alternative solutions to problems
- extending problems and solutions to more general case
- solving problems algebraically, geometrically, numerically
- asking clarifying and extending questions

Habit # 4: Making connections

Students should develop the habit of

- Linking algebra, number, geometry, statistics and probability
- Finding/devising equivalent representations of the same concept
- Linking math concepts to real-world situation

Habit #5: Communicating mathematics

Students should develop the habit of

- listening, reading, writing and speaking about mathematics
- noticing faulty, incomplete or misleading use of numbers

Habit #6: Reflecting and self-directing learning

Habit is a cable; we weave a thread of it each day, and at last you cannot break it. – Horace Mann

All these are only possible in an environment where students are engage in problem solving and mathematical investigation tasks.
