Accessibility Features

  • Accessible graphs. Students who are blind can determine the shape of a graph through audio trace. The pitch of the tone increases or decreases depending on the shape of the wave or graph.
  • Support for screen readers. The calculators communicate with screen readers, which voice additional cues to indicate a student’s location within an expression (numerator or denominator, superscript or subscript, baseline, etc.).
  • Colors that have sufficient contrast
  • Adjustable font-size settings for students who have low vision

The Smarter Balanced Desmos calculator is also compliant with the latest web accessibility standards.
