Object Details
- Milton Bradley Company
- 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 subtraction problems that emerged.
- The set consists of fifty cards, printed with subtraction problems on each side. The problems are written crosswise, with a box for the answer. The solution is printed in red in the upper left corner on the back. Another card lists basic subtraction facts (vertically), and three cards give work sheets and directions.
- A mark on the paper box reads: MILTON BRADLEY (/) NEW MATH (/) FLASH CARDS (/) SUBTRACTION. Another mark reads: [copyright] 1965. A third mark reads: 4592.
- These and several other sets of flash cards were donated by elementary school teacher Marjorie A. Naidorf.
