Reply To: UEB math Number Lines
Hello,
It is the Tactile Graphics Committee's stance that we follow the suggestion in the 2010 Guidelines and Standards for Tactile Graphics (TGG) for texts transcribed using UEB Guidelines for Technical Material: number lines for kindergarten through grade 3 should be done as tactile graphics with raised lines (TGG 6.5.1.12) while grades 4 and up may be done using braille symbols (TGG 6.5.1.13).
However, even when the number line in grades 4 and up is created using braille symbols, it is still recommended to create any lines above the number line using tactile lines. In addition, if a number line must be rotated to vertical, it will be always done using tactile lines.
Thank you for your question.
Rebecca
