Rachel, Sylvia and Lola each receive the same homework assignment, but they only complete part of it. Rachel completes ⅙ of her homework. Sylvia completes ½ of her homework. Lola completes ⅓ of her homework. Write the amount of homework each girl completes from least to greatest. Draw a picture to prove your answer. RachelSylviaLola ½ ⅓ ⅙ Sylvia did the most homework because ½ is the largest fraction of the assignment.

1 is the same as 1. Thumbs up if you agree. Here is 1 liter of soda and 1 can of soda. Is 1 still the same as 1? The liter bottle holds more, so it is a larger whole than the can of soda. How MANY we have is the same (1), but how MUCH we have is different.

Let’s explore how MANY versus how MUCH using fractions: Let’s say you and your brother both have a glass of juice this morning. How full is your glass? How full is your brother’s glass?

True or False: ½ is larger than ¼, so your brother drank the most juice. False: The containers aren’t the same size so we can’t accurately compare the amount of juice.

Can I accurately compare the fractions in these two figures? Why or Why Not?

What about these two? Yes; these two figures can be compared because they are the same shape and size.

What about these two? Yes; these two figures can be compared because they are the same shape and size.

What fractions do they show? Which fraction is greater? 1/3 is greater than 1/6

Problem Set Everything is different … … Now that I know fractions!
