great math manipulative to have on hand for long car rides, trips
to the dentist or other times when young children need something
to keep them occupied. Kids love to play with geoboards and a package
of rubber bands. Don't limit that geoboard to your preschooler though.
There are many ways to use geoboards to teach math concepts. Here
are a couple of ideas from our Geometry Unit Study. Pop down to
the resource list to find online lesson plans, virtual geoboards,
and places to get your own geoboard and geoboard activity resources.

- Using a geoboard
try to make a shape that has more sides than angles. Try to make
a shape that has more angles than sides. Can it be done?
- Use your
geoboards to make the following shapes: polygon, triangle, square,
rectangle, quadrilateral, pentagon, and hexagon. How would you
show a line segment on a geoboard?
the Concept of Triangle and the Properties of Polygons
and the Geoboard
This sixth grade math lesson plan helps students visualize the
concepts of squares, rectangles, triangles and polygons and explore
line segments, areas, and perimeters.
Three mathematical activites that require geoboards.

in the Classroom
"This unit deals with the length and area of two-dimensional
geometric figures using the geoboard as a pedagogical device.
Even though your students may have already seen some of this material,
it is still likely that many of them have only a superficial understanding
of length and area. It's quite amazing, for example, how many
students have trouble distinguishing between perimeter and area
- even secondary students confuse the two.
A typical student's
understanding of units is even more problematic. Ask your students
to describe a square inch, for example. It's unfortunate, but
true, that many write "in2" without really understanding
what it means. But with a geoboard, a student can see the area
of a rectangle, say, and will readily count the square units making
up such a geometric figure. Indeed, "square unit" takes
on a whole new meaning with the geoboard."

Using the virtual geoboard kids can solve a variety of geoboard

To better appreciate the power of Pick's theorem try answering
a few questions below without invoking the theorem. The questions
are posed for the geoboard. Learn more about Pick's theorem at

a Patter Block Geoboard with a 10 x 10-pin isometric array on one
side, enabling children to loop actual-size geometric Pattern Blocks
shapes. On the reverse, an 11 x 11-pin coordinate grid can be used
for plotting, map skills practice, and graphing. It sells for $4.95.
They offer a Double Sided Geoboard with a 5x5 pin grid with coordinates.
On the reverse is a 12-pin Geocircle that includes radius and diameter
pegs. It sells for $2.95. A complete listing of geoboards and geoboard
resources can be found at the Cuisenaire
Hill offers Geoboard
Activity Sheets. These 23 blackline masters teach students to
locate points, change figures, create symmetry, and measure area.
Available for $8.99. geoboard-activity_sheets_book.jpg
They also offer Geoboard
Pictures for Little Kids. Children will develop their fine motor
and visual discrimination skills as they copy these 16 adorable
pictures on the included 5 x 5 pin plastic geoboard. Includes eight
colorful two-sided picture cards, each 8" x 8" (20.5 x
20.5cm), one plastic geoboard, and over 400 rubber bands. The set
sells for $12.99.
They also offer
two books titled Math Discoveries with Geoboards, one for Kindergarten
and 1st grade, the other for 2nd and 3rd grades. Students will discover
how shapes are alike and different, how shapes can be subdivided
or changed into other shapes, and the relationship between sides
and angles. They will explore congruency, symmetry, area, and perimeter.The
hands-on activities actively engage students in doing mathematics,
which is emphasized by the National Council of Teachers of Mathematics
(NCTM). This book contains 40 reproducible student activities, two
investigations,a game, award certificates, and sample solutions.Each
sells for $7.99. K-1st,
