发明名称 Reading teaching aid
摘要 The reading teaching aid is a transparent substantially right triangle shaped sheet, preferably plastic. The sheet has linear legs and a staircase shaped hypotenuse. The sheet is used to teach a learner to read symbols, such as letters, characters, syllables or words, by covering the symbols with the sheet thereby highlighting the symbol(s) to be read. The stepped shape permits the user to successively highlight larger groups of adjacent symbols to learn to read or pronounce progressively larger groups of the symbols.
