Reading teaching aid

A reading teaching aid comprising two substantially coplanar masking elements which when in use lie against a supporting surface upon which words or syllables are adapted to be localized to enhance readability by a pupil, said substantially coplanar masking elements each including at least one edge collectively setting off between said edges a viewing area, said substantially coplanar masking elements being located one each on respective first ends of a pair of elongated arms which are resiliently hinged together by a resilient hinge at second ends of said elongated arms, and each of said elongated arms having finger reception means adjacent said coplanar masking elements which include a substantially horizontal portion and an adjacent upstanding portion to allow said substantially coplanar masking elements to be pressed onto a supporting surface and moved toward and away from each other by finger forces applied to said upstanding portions and against the resilience of said resilient hinge to thereby selectively vary the distance between said edges and thus the dimensions of the viewing area therebetween.
