Description
Each of these one hundred paper cards shows the sum to two integers between 0 to 9, written in a vertical column. The total is given on one side of the card but not the other. Cards are notched at one bottom corner to make them easier to sort.
The cards are stored in a dark brown paper box, with instructions for use given on the lid. A label there reads: SELF-TEACHING (/) Flash Cards (/) No. 2135 (/) ADDITION (/) By GARRY CLEVELAND MYERS, Ph.D. (/) Cleveland School of Education.
The cards were designed by Garry Cleveland Myers of the Cleveland School of Education and published by The Harter Publishing Co. of Cleveland, Ohio. They sold for $1.00. Myers received his PhD. from Columbia University in 1913. He was at the Cleveland School of Education from 1920 to 1927. The Harter Publishing Company was in business in Cleveland from at least 1927 until at least 1938.
