I am always looking for ordinary items that can
be used in the classroom as manipulatives. I'm a firm believer in the
Conceptual Development Model which advocates teaching the concrete (using
manipulatives) prior to moving to the pictorial before even thinking
about the abstract. When I was at the Dollar Store (a great, inexpensive
place to purchase school stuff) I saw sets of dominoes for $1.00 each.
Since they were inexpensive and readily available, I decided to create several math
activities and games to introduce, reinforce, or reteach math concepts.

Think about it; if you
lay a domino horizontally, you have a two digit number. Put two dominoes
side-by-side, and a four digit number is created. Now you can work with
place value, estimation, or rounding. How about lining up dominoes in a
column, and working on addition (with or without regrouping) or subtraction
(with or without renaming)?

If a domino is placed
vertically, you immediately have a fraction. Placed one way it is a
proper fraction, but rotated around, it is an improper fraction which can then
be reduced. A fraction can also be changed into a division
problem, a ratio, a decimal, or a percent.

So think outside that box of dominoes and use them as an inexpensive math manipulative because there is
