BRAILLE AND ABACUS
TOOLS FOR LEARNING
AND ACCESSIBILITY
Presented by: C3
INTRODUCTION
BRAILLE AND ABACUS ARE TWO IMPORTANT TOOLS THAT
HELP PEOPLE WITH DISABILITIES, ESPECIALLY THOSE
WHO ARE BLIND OR VISUALLY IMPAIRED, LEARN AND
PERFORM EVERYDAY TASKS.
WHAT IS BRAILLE
• Braille is a writing system for people who are blind or visually impaired.
• It uses raised dots arranged in a pattern that represents letters,
numbers, and symbols.
• Invented by Louis Braille in the early 1800s.
• Read by running fingers over the dots.
• Helps blind individuals read books, signs, and even digital screens.
HOW BRAILLE WORKS?
• Uses a six-dot cell system
arranged in two columns of
three dots each.
• Different dot combinations
represent letters,
numbers, and punctuation
marks.
IMPORTANCE OF BRAILLE
Helps blind individuals
become independent
readers and writers.
Used in education,
banking (Braille money),
and public places
(elevators, signs, menus,
etc.).
Learning Braille increases job
opportunities for visually
impaired individuals by
enabling them to work in fields
like teaching, law, and
administration.
WHAT IS ABACUS?
• The Abacus is an ancient counting tool used for
calculations.
• Made of a wooden frame with beads that slide on
rods.
• Used for addition, subtraction, multiplication, and
division.
• Still used today for math education and by visually
impaired individuals.
TYPES OF ABACUS
Chinese Abacus (Suanpan)
Has two sections, with beads
above and below a divider.
TYPE OF ABACUS
• Japanese Abacus
(Soroban) – Has one
bead on top and four
on the bottom.
TYPE OF ABACUS
Modern Adaptations – Some
abacuses are made for blind
users with tactile features.
IMPORTANCE OF
ABACUS
• HELPS DEVELOP MENTAL MATH SKILLS.
• USED BY VISUALLY IMPAIRED INDIVIDUALS TO
PERFORM CALCULATIONS WITHOUT WRITING.
• AIDS IN EARLY MATH LEARNING FOR CHILDREN.
