Developing a strong number sense isnt quick or easy, but it also isnt magic. Its like common sense, but for math. Number sense is useful throughout life and generally makes all things mathematical much easier.

Math problems that have a serious bearing on real life rather than the silly, unrealistic problems that most students are usually exposed to can be stimulating too, especially for older kids. Edward Zaccaros book 25 Real Life Math Investigations is another rich source for this type of problem.

A related strategy is to study the mathematics of interesting physical phenomenon. The question is, how can we help children (or teenagers, or adults) develop number sense?

In the most basic terms, people who think more deeply about math are more likely to develop and intuitive sense of how numbers act. Heres an example. Pick a number from 1 to 9. What happens? Why? (Can you figure it out? Hint: what is 37,373,737 times 3?) Thinking about problems like this, and especially talking about them can be a great way to develop number sense. Done right, it might even be fun.Some people are just better with numbers than other people.

Certain games tilting pad thrust bearing suppliers are good ways to develop number sense, too. An older, better known game that can also serve this purpose is Risk. The people who are better with numbers have something that math teachers sometimes refer to as number sense. Using the density formula while designing model boats is one of my favorite projects using math.
