EquaBeam Balance

Help students understand equality with this self-correcting balance. This unique balance has a double-sided crossbeam with imprinted numbers on one face, and a blank face with tracks to hold value strips.

As a hands-on, interactive math manipulative for students, the EquaBeam is unparalleled in versatility and sophistication. It is the perfect manipulative for reinforcing the number facts and revealing the structure of arithmetic—that the facts are commutative (a+b = b+a), associative, [(a+b)+c = a+(b+c)], and distributive [a(b+c) = ab+ac]—thus aiding mental arithmetic and reducing the number of facts to be learned. By relabeling the pegs on the channel side, the EquaBeam can be used to teach time, money, measurement, fractions, decimals, percent, and more in conjunction with other manipulatives.

• The zero peg is aligned with the pegs for the numerals 1-10 as on a number line.

• Together, the front and back pegs for a numeral hold 10 weights which allows the demonstration of the multiplication facts and division facts up to the decades, for example, up to 10 x 5 = 50 for the multiplication facts for 5 and up to 90 ÷ 9 = 10 for the division facts for 9.

• The beam extends out to 12, instead of 10, on either side to utilize the divisibility of 12 for multiplication (like 3 x 4 = 12), division (like 12 ÷ 6 = 2), and fractions (like 1/3 + 1/4 = 7/12) and to capitalize on the fre-quency of 12 in everyday equivalences such as twelve 5-minute intervals in an hour, 12 inches in a foot, and 12 months in a year.

• The channel side of the beam facilitates changing topics with strips that fit in the channel and re-label the pegs.
