Cookie Monster's Counting Scale is a Sesame Street educational toy produced by CBS Toys in 1982. The toy comes with a set of plastic numbers that can be placed on either side of the scale to show the properties of addition and subtraction.
For example, when the 8 is placed on one side and the 5 and 3 are placed on the other, the scale balances out, and the chocolate chip cookie sits directly on Cookie Monster's open hand.
This toy is a new version of a previous toy, The Count's Counting Scale, produced by Questor under the Child Guidance label in 1978.
