Which among the following Learning-Teacher Resources (LTRs) are most appropriate for visually challenged students in mathematics classroom?
A. Geogebra
B. Taylor’s abacus
C. Computer
D. Spreadsheet
Choose the correct options:

Correct option is B

Taylor’s abacus is the most appropriate Learning-Teacher Resource (LTR) for visually challenged students in a mathematics classroom.
Computer can be equipped with specialized software and accessibility features like screen readers and voice recognition, making them useful for visually impaired students. However, the effectiveness depends heavily on the software used and the student's familiarity with the accessibility tools.
Spreadsheet like those in Microsoft Excel or Google Sheets, can be powerful tools for organizing data, performing calculations, and analyzing information. For visually impaired students, accessibility can be enhanced with screen readers, though navigating complex spreadsheets might require a steep learning curve and additional adaptations.
GeoGebra (a) is a dynamic mathematics software that combines geometry, algebra, spreadsheets, graphing, statistics, and calculus in one easy-to-use package. While immensely useful, its standard interface relies heavily on visual elements, making it less accessible for students with severe visual impairments unless adapted versions or additional support tools are used.
