FOR 3RD GRADE

Students don't need to draw a benchmark fraction in order to compare the two fraction. Fraction with common numerators may be compared and ordered using the denominators as a guide.Fraction with larger denominator is the lesser fraction.

12b) additional question: without drawing a benchmark fraction, which is greater between the two fraction 3/10 and 3/8. How about 3/8 and 3/4 ?

 

I show the number line as a proof that larger denominator is lesser if the fractions have the same numerator.

So did you get the correct answer , which is greater between 3/10 and 3/8? You are right. 3/8 is greater than 3/10. Can you write it to numerical form? 3/8 > 3/10 that is how you write it in numeral form.

Now how about between 3/8 and 3/4, which fraction is greater? You are right. 3/4 is greater than 3/8. Can you write it to numerical form? 3/4 > 3/8 that is how you write it in numerical form.
