ABSTRACT:
A self-corrective, reversible device comprising a handled, slotted framework, on each side of which the top frame is imprinted with inverse mathematical symbols, below which is a number line from one through ten in ascending and descending order. Below the number line, nine channeled horizontal rows each contain ten grooved, colored, movable, workpieces. The first four rows on side "A" teach counting, addition, subtraction and place value. These workpieces have the following values: Row one, "1" each; Row two, "1" each; Row three, "10" each and Row four, "100" each. Workpieces in each row are the same color, but each row is a different color. Corresponding with these four rows in both value and color are four boxes imprinted on an erasable surface contained within the framework. The remaining five rows on side "A" teach large and small letters of the alphabet, phonics and consonant blends. These workpieces are each colored in one of various monochromatic shades with the ten workpieces in the last row also each having one of a variety of textures. On the side of the frame, numerals and color words correspond with the workpieces. Workpieces are in Braille, as Braille is designed in multiples of ten. The reverse, or multiplication/division side, has workpieces with from two through nine dots, with workpieces in the top row each bearing two dots and each succeeding row increasing by one dot per workpiece. Imprinted answer-backboards are designed for insertion in top of the frame for self-correction.
