New Math Flash Cards, Addition-Subtraction

Description
From the 1950s, particularly after the launch of the Sputnik satellite in 1958, American mathematicians and mathematics educators introduced a variety of reforms in mathematics teaching dubbed “The New Math.” This set of flash cards reflects the way of presenting addition and subtraction problems that emerged.
The set consists of flash cards showing sums written out horizontally on one side and differences written out horizontally on the other. A blank square indicates where the answer is to go. The cards are numbered from 1 to 81, with several missing and some duplicates. One unnumbered card may be card one. The cards are cut off at one corner, like punch cards. Another card lists on one side "Basic Addition Facts" for sums as large as 9 + 9, and "Basic Subtraction Facts" on the reverse side. Two further cards provide explanation.
An explanation card for a similar set of flash cards for teaching multiplication and division is included, but none of these cards. Seven further cards, apparently from another set, give sums and differences written vertically.
A mark on the cardboard box holding the cards reads: MILTON BRADLEY COMPANY (/) SPRINGFIELD (/) MASSACHUSETTS. Another mark reads: NEW MATH(/)FLASH CARDS. Another mark reads: ADDITION-SUBTRACTION. A further mark reads: [copyright] 1965. The set has the maker’s number: 7020.
