 And how do you know? What takes longer and how do you know? Oh, you got put on the spot, Emily. What takes longer and how do you know? I think it's maybe four-six because if one half of a minute equals thirty minutes... Rhett, rephrase what you're thinking. One half of a minute equals thirty minutes? One half of a minute equals thirty seconds because you're saying half of a minute and a minute is sixty seconds and half-sixty is thirty. So I think four-six is more than one half because it could be more seconds than thirty seconds. How is Emily using her knowledge of fractions to correctly state that? How is she using her knowledge of fractions and what she knows about benchmark fractions and where fractions are in terms of greater than certain benchmarks or less than certain benchmarks? Gerilyn, what do you think? So in other words, how does she know that four-six is greater than one half? Let's say we didn't even know how many seconds equals a minute. Just looking at those fractions, how do you know that four-six is greater? I think that four-six is greater just like Emily said because if you divide six times sixty which is the seconds it'll give you about like ten. I think let's forget about division. Let's focus on our fractional knowledge. What do you know about halves and what do you notice about four-six? That four-six is greater than a half because when you simplify the four-six it'll give you two-thirds and two-thirds is greater than a half. Very good. But what else do we know about that six and how is it important to really analyze that six, Gabby? Four-six is greater than a half because a half of six is three and the fraction will be three over six and this is one more than a half. Very good. So what Gabby knows is this represents one half. One half represents one half. She knows that four-six is greater than half because what is half of six? Three. But do we have three parts of that six? We have four-six. All right, so we have more than that half.
