The Math Balance is a great tool for visualizing simple mathematical equations and | ||||
number relationships. When a weight is placed on a number peg (i.e. 6) on the balance, the | ||||
weight appears to take on the numerical value of that peg and causes the balance to tilt. | ||||
In order to level the balance, a weight must be placed on the opposite side of the balance | ||||
arm, either on the equivalent peg (6) or two or more different pegs that equal the same | ||||
number (i.e. 5+1). |

ORDERED PAIRS |
|
|
| |
Find all the ordered pairs for a number by combining two weights to balance the | ||||
opposite weight. For example, place a weight on the 10. To balance, place a weight on the | ||||
9 and on the 1 (9,1) and then on the 8 and on the 2 (8,2). Continue until all ordered pairs | ||||
have been found. Find all the ordered pairs for several different numbers. | ||||
