Math 402, Methods of Instruction for
Math, K-9, instructor Ellen Hines
reviews a problem for her
students. The Math Education Lab
contains a variety of resources to
aid prospective math teachers,
including pattern blocks, geoboards
and base blocks, as well as journals
and books.
In NIU's Math Education Lab, brightly colored Macintosh computers sit
all in a row.

Hundreds of Tupperware containers line the shelves on the wall, each
containing a different material used in demonstrating math concepts,
such as pattern blocks, geoboards and base blocks.

The shelves on both sides of the room are filled with math journals
and books.

About 20 students began to pile into DuSable Hall, Room 306, for Math
402, Methods of Instruction for Math, K-9. This class is different in
that the students become the teachers.

Students are required to demonstrate how to complete a problem. They
were given a sample problem involving Auntie Mae, a candy store owner
who received an order for 432 pieces of candy. She got a call asking
her to mail the candy in three separate equal packages. How much candy
will be in each package?

Students used base boards to simulate how the candy would be divided.
The boards consist of flats, which are 10-by-10, or 100 squares; rods,
which are 10 squares long and units, which are single squares.

The students first divided the flats into three groups, then the rods
and the individual units. Exchanges were made if necessary.

They determined that 144 pieces of candy would be in each package.

The students then watched a video in which this same procedure was
used with actual children. The children responded well to this method
and showed an understanding of division.

NIU math professors feel that the lab, which is used for all the math
methods courses, contains many useful resources for the students,
including hundreds of current teaching books and journals.

Helen Khoury, a math professor, said students understand something
best when they have to teach it to someone else.

"The math education lab contains a remarkable collection of materials
for prospective teachers," said Mary Shafer, a math professor.

Shafer said many of the materials aid in developing students'
understanding of place value, fractions and decimals, and concepts in
geometry and measurement.
