There is no need to have different
colors among the positive tiles. The positive tiles could all be of one color.
The negative tiles should all be red. The tile sets are packaged in sandwich bags
and enough sets are prepared so that each student in the class has his/her own set.
( I also produced an "enlarged" tile set with magnets on the back for
demonstrations at the chalkboard. Magnetic strips can be found in any craft department. )
Many of the commercial versions of algebra tiles are made from plastic and possess a
"projectile" quality. I have found that the homemade tiles are seldom
"airborne" since they are aerodynamically deficient. : )
*Hint: When making your tile sets, consider asking for assistance from other
adults, retired persons, younger children, and student helpers. My retired mother
("grandma") was most willing to assist in making these
manipulatives.
Template for homemade tiles for algebra:
| If you would
like a grid to use as a template to create your tiles, click on the
Download Template at the right.
A larger (full page) grid, suitable for printing,
will appear in .pdf format. If
your copy machine can process card stock paper, you can transfer the template directly to
the card stock. If not, you may need to measure and cut the tiles by hand.
Template was
modeled after template appearing in CORD Applied Mathematics-Unit 23. |
