Lesson Plan

From Dollars to Degrees

Students will be able to correctly transcribe expressions involving common special symbols (currency, percent, degree) and simple numeric fractions.

Mastering these transcriptions is crucial for effective communication and literacy in Braille, enabling accurate reading and writing of mathematical and symbolic expressions.

Audience

Adult Learners

Time

30 minutes

Approach

Guided instruction and hands-on transcription practice.

Materials

Whiteboard or projector, Special Symbols Slide Deck, BrailleNote or slate and stylus, Money and Fractions Braille Puzzles, Money and Fractions Answer Key, Real World Math Worksheet, and Real World Math Answer Key

Prep

Teacher Preparation

15 minutes

Step 1

Warm-up & Review of Indicators

5 minutes

  • Greet students and briefly review previously learned Braille indicators. Ask students to transcribe a few simple words or numbers that require indicators to refresh their memory.
  • Facilitate a quick discussion about why indicators are important in Braille transcription.

Step 2

Introduce Special Print Symbols ($, %, °)

7 minutes

  • Use the Special Symbols Slide Deck to introduce the Braille symbols for currency ($), percent (%), and degree (°).
  • Show examples of each symbol in print and their corresponding Braille transcription.
  • Explain the rules and context for using these symbols, emphasizing the importance of accurate placement and spacing.

Step 3

Guided Instruction: Simple Numeric Fractions

8 minutes

  • Explain how to transcribe simple numeric fractions (e.g., 1/2, 3/4) and mixed numbers (e.g., 2 1/3) in Braille.
  • Use the Special Symbols Slide Deck to demonstrate step-by-step transcription.
  • Work through several examples together as a class, encouraging student participation and answering questions.
  • Pay special attention to the fraction line and mixed number spacing.

Step 4

Practice Transcribing Mixed Problems

7 minutes

  • Distribute the Money and Fractions Braille Puzzles activity.
  • Students will work individually or in pairs to transcribe various expressions that combine special symbols and simple numeric fractions.
  • Circulate around the classroom to provide individualized support and feedback.

Step 5

Wrap-up & Cool Down

Welcome! Let's Review Indicators

What are Braille Indicators and why are they important?

Welcome students. Briefly review basic Braille indicators. Ask a few quick questions to engage prior knowledge.

Money Matters: The Dollar Sign ($)

Print: $5.00

Braille Transcription:

⠐⠋⠑⠒⠴⠴

Key Points:

  • Placed before the number.
  • No space between the dollar sign and the number.

Introduce the dollar sign symbol in print and Braille. Provide clear examples and explain its use.

Percentage Power: The Percent Sign (%)

Print: 75%

Braille Transcription:

⠼⠛⠑⠴⠴⠨⠴

Key Points:

  • Placed after the number.
  • No space between the number and the percent sign.

Introduce the percent symbol. Show examples and discuss its application.

Degree of Detail: The Degree Sign (°)

Print: 90° F or 45° angle

Braille Transcription:

⠼⠊⠴⠘⠔⠋⠀⠕⠗⠀⠼⠙⠑⠘⠔⠀⠁⠝⠛⠇⠑

Key Points:

  • Placed after the number.
  • No space between the number and the degree sign.

Introduce the degree symbol. Show examples and discuss its use in temperature and angles.

Fractions Fun: Simple Numeric Fractions

What is a simple numeric fraction?

  • A way to represent parts of a whole.
  • Made of a numerator, a fraction line, and a denominator.

Examples:

  • 1/2
  • 3/4

Transition to fractions. Explain the concept of simple numeric fractions.

Transcribing Fractions in Braille

Braille Fraction Line:

⠌

Example: 1/2

Braille Transcription:

⠼⠁⠌⠃

Example: 3/4

Braille Transcription:

⠼⠉⠌⠙

Demonstrate the Braille transcription of simple fractions step-by-step. Work through examples with the class.

Mixing It Up: Mixed Numbers

What is a mixed number?

  • A whole number and a fraction combined.

Example: 2 1/3

Braille Transcription:

⠼⠃⠀⠼⠁⠌⠉

Key Point:

  • A space separates the whole number from the fraction in Braille.

Explain mixed numbers and their Braille transcription. Provide examples for practice.
