Though they can strike fear in many a student's (and perhaps teacher's!) heart, fractions boast a rich history interwoven with human civilization. The word "fraction" itself stems from the Latin "fractio," meaning "to break," aptly reflecting their role in dividing wholes.
Origin
While their birthplace remains a mystery, evidence of their use stretches back to ancient Egypt, India, Babylonia, and Greece. Around 3000-1900 BCE, merchants in the Indus Valley (present-day India and Pakistan) utilized fractions for planning and trade.
Babylonia
The Babylonians, known for their precise astronomical and calendar calculations, employed fractions for greater accuracy.
Greece
In ancient Greece, mathematicians like Pythagoras and Euclid laid the groundwork for future advancements by formalizing concepts like ratios and proportions.
Egypt
Closer to home, Egyptians often received wages in loaves of bread or beer, frequently divided among groups of workers. Imagine – fair compensation depended on a solid grasp of fractions!
Today
Though loaves of bread are no longer our standard currency, fractions, or their influence, permeate daily life. From baking perfect cakes to dyeing hair, their presence spans engineering, finance, and countless other fields.
So, let's demystify the concepts of fraction, explore common challenges encountered in teaching fractions and suggest a clear pathway for teaching them.
