    Hello! I am having a debate with my math colleagues about what grade level do students convert or understand fraction and decimal equivalencies? I know in 5th grade they learn about tenths and hundredths in both fraction and decimal forms. But what about 5/8, 3/5…as decimals…etc? What is your opinion?

    Also, I have noticed in a lot of resources for suggested units, it begins in 6th grade with ratios and proportions. Why?

    Thanks.

    In the Common Core decimals are treated simply as a different way of writing fractions with denominator 10, 100, and so on. So Grade 5 students can certainly see the equivalence of 3/5 and 0.6 because they can see the equivalence of 3/5 and 6/10. For 5/8 you are getting into 1000ths, so that would have to wait.
