Someone popped a question with a denominator other than multiples of 10.
They worked with 1/2 - 0.5- that was easy. 1/4- 0.125, they kept halving the fraction to reach 1/64 - which gave a decimal in the millionths.
The next discovery was 1/3. They were delighted to see a never ending pattern 0.3333333...
2/3 gave a 0.6666666...
I was delighted. You'll have stumbled upon a special set of numbers- repeating decimals!
The next idea was to hunt for more such numbers. Let's try 1/7 was a suggestion, 1/9.. let's see where it goes
Now a bunch of girls is having fun dividing large decimal numbers - "Fearsome Fractions" to see the long chain to decimals it produces.
I'm having fun each time a new Montessori Math material is introduced. It brings out so much potential.
