A literacy development device includes a light source that provides a general white illumination area and an adjustable light within the illumination area, both from the same light source. The adjustable light can be changed in shape and color through a LCD screen provided within the device. The device contains a rechargeable battery and various buttons for changing functions, light parameters, and other controls. The device is preferably usable in teaching applications, especially with children and other students with learning and/or attention issues. The device is useful in drawing attention to certain areas of a surface that includes written language, including a letter, a group of letters, a word, or a sentence, through use of the adjustable light to highlight, underline, or otherwise draw visual attention to a particular area of the surface within the illumination area.
