From the 1950s, particularly after the launch of the Soviet Sputnik satellite in 1958, American mathematicians and mathematics educators introduced a variety of reforms in mathematics teaching that went under the name “The New Math.” This set of flash cards reflects the way of presenting addition problems that emerged.
The set includes 50 cards showing sums of one digit numbers. A sum is written out horizontally on each side of each card. The sides are numbered from 1 to 50 on one side and from 50 to 100 on the other. A "sliding number cover" fits over a card to cover one term in the "number sentence." The child is to figure out the answer. A window in the back of the cover reveals the correct answer written on the back of the card. In addition to these cards, there is a card listing "Basic Addition Facts" (written vertically, with answers) and "Basic Addition Combinations" (written vertically, without answers). Four cards give tips and instructions for teachers and parents.
A mark on the top of the box reads: NEW MATH (/) ADDITION (/) FLASH CARDS. A second mark reads: ED-U-CARDS. Another mark reads: [copyright]1966 ED-U-CARDS MFG. CORP., L.I.C., N.Y.
