Question: Should a second-grader be using a calculator?

By Liz Rusch

Q: I observed my daughter's second-grade math class recently and was upset
to see the kids using calculators. How will she learn to do basic math if
she uses a calculator in class?

A: "Calculators in a second-grade classroom do not mean that children
aren't learning elementary math facts," says Donald Dessart, Ph.D., a
professor of mathematics and education at the University of Tennessee, in
Knoxville. "On the contrary, calculators can boost basic skills by letting
kids check their pencil-and-paper work, learn how to estimate, and work on
problems that would be too complex for them to try without help."

In 1986, Dr. Dessart and a colleague reviewed 79 studies that compared the
basic math skills of students in classes that used calculators with those
of students in classes that did not. They found that students with access
to calculators actually did slightly better on tests of basic skills-a
point or two on a 100-point scale.

Still, you should make sure calculators are being used properly in your
daughter's class. Ask the teacher if she still expects children to
memorize the basics, like multiplication tables. The answer should be yes.
Then find out in what context the students are using calculators. "If the
children depend on calculators to add three plus four, that's a problem,"
says Dr.Dessart. A more reasonable use, he says, is for kids to estimate
the cost of buying three items at one price and five items at another
price, and then use a calculator to check their answer.

Calculators also make it easier for kids to explore number patterns. For
instance, a second-grader might use a calculator to discover that adding
two even numbers will always result in an even-numbered answer. And adding
any number over and over on the calculator can clarify the connection
between addition and multiplication.

Another reason teachers include calculators in math class is to help kids
learn to use them judiciously, says Mary Lindquist, Ph.D., professor of
math education at Columbus State University, in Columbus, Georgia, and past
president of the National Council of Teachers of Mathematics. "We know
that kids are going to use calculators in their everyday lives, so we have
an obligation to teach them when it's appropriate to use them and when it's
not," she says.

You can support wise calculator use at home too. For instance,
Dr.Lindquist suggests explaining to your child that although you use a
calculator to do your taxes, it's still easier to do simple calculations,
like computing a tip, in your head.
