Add-A-Count Scale

images for Add-A-Count Scale
During the 1950s, the number of children in the United States grew rapidly. Several manufacturers introduced toys intended to communicate elementary ideas. The Add-A-Count scale, made by Child Guidance Toys of New York City, well illustrates this trend. The red, white, and blue plastic toy is a balance with weights in the form of numbers. The weight of the weight is proportional to the size of the number. Hence a "3" on one arm will balance a "2" and a "1" on the other. There are two weights for each digit from 1 to 5 and one weight for each digit from 6 to 9, making a total of 14 weights. The weights and scale fit in a paper box, which has on it a drawing of a girl playing with the toy. In the 1960s, the toy was sold by instrument dealers like Edmund Scientific Company of Barrington, New Jersey. It sold for $1.00—by 1968 the price was $1.50.
