From Dollars to Degrees: Braille Symbols

Understanding and transcribing special symbols in braille opens up a world of information!

Welcome students and briefly recap the purpose of learning braille symbols for common print symbols.

The Dollar Sign ($)

  • Braille Symbol: ,$
    - Placement: Placed directly before the number it modifies.
    - Example: $5.00 becomes ,$500

Introduce the dollar sign braille symbol. Emphasize its placement and how it affects the following numbers. Provide a few simple examples and ask students to try them.

The Percent Sign (%)

  • Braille Symbol: .%
    - Placement: Placed directly after the number it modifies.
    - Example: 25% becomes 25.%

Introduce the percent sign braille symbol. Explain its usage and provide examples. Discuss how it's different from the dollar sign in terms of spacing.

The Degree Sign (°)

  • Braille Symbol: ,°
    - Placement: Placed directly after the number it modifies.
    - Example: 72°F becomes 72,°f

Introduce the degree sign braille symbol. Explain its common use cases (temperature, angles) and how to transcribe it.

Simple Numeric Fractions

  • Fractions help us describe parts of a whole.
    - Example: 1/2, 3/4, 5/8
    - We use a special symbol for the fraction line!

Transition to simple numeric fractions. Explain the components: numerator, fraction line, denominator. Show the braille equivalent.

Transcribing Fractions

  • Braille Fraction Line: /
    - Example: 1/2 becomes 1/2
    - Example: 3/4 becomes 3/4
    - Example: 5/8 becomes 5/8

Show specific examples of simple fractions and their braille transcriptions. Highlight the fraction line symbol and how it separates the numerator and denominator.

Putting It All Together!

Today, we learned:
- Dollar Sign ($)
- Percent Sign (%)
- Degree Sign (°)
- Simple Numeric Fractions (1/2, 3/4)

Summarize the key symbols learned and encourage students to ask questions before moving to practice activities.
