Lindsay uses fraction models to identify a fraction greater than 1.  Created by Lindsay Spears.

• I don't understand, they were separate shapes so shouldn't the first one have been 2/3 and the last one be 3/3? Why put them together if they are separate?
• We are looking at how many pieces of the whole. One circle is a whole. (We find it helpful to say one whole pizza). If we ate two slices and ate three slices, we ate 5/3 or 5 thirds. One whole is still only one pizza no matter how many slices we eat. We want to know what fraction we ate, so we count up all the shaded slices.
• This was obviously confusing to me. I totally did not get how that was showing a fraction greater than one. I mean, to me it looked like 2/3 and 3/3. Why couldent you just simply add the numerators?
• You could just add the numerators, which gets you 5/3.
But, you need to recognize that it is an improper fraction and that it is larger than 1 which is what this video is trying to show you.
5/3 = 1 2/3 (one whole unit and 2/3 of another unit).
• how am i supposed to recognizied fractions that are greater then 1?
• Well 5/3 would be 3 equal pieces with 5 of them shaded in but you would need like, 2 pies with three slices and someone ate 5 of the three slices, I know that would kinda sound like 5/6 but it's not it's 5/3 so that means the person a 5 slices of two pies with 3 pices.
• Im so bad at fractions Im SO HAPPY MY TEACHER IS TEACHING ME FRACTIONS
• i don't know what to write when it says What part of the square is shaded.
• lets say you have 1 half of a candy bar you would rite it like 1/2. or you have 3/3 of crowns that means you have a whole box but you only get 1 quarter of a box. so you get 1/3 of a box of crowns. hope this is what you asked.
• when I have a number like this 5/5 that means one why? and why cant it mean two
• because if you had one shape then you divided it into fifths you still have one shape. if you colored 5 of the 5 sections then you don't suddenly have two shapes appear that are all shaded in.
• is there another way to write,say something like 2 3rds because my keyboard doesn't have that hifin thing-a-mo-bob whatever its called! (the thing that goes in the middle of the numerator and denominator)
• You could also represent it by adding a dash. For example 2/3. The dash is located by your right hand shift button
• can fractions represented in a decimal form
• Yes, it can, if you had 1/2 then that would be .5 because 1.0 is a whole 0.0 is well 0 so 1/2 would be 0.5 same with 3/4 = .75, 1/4 = .25 ect.
• If there was was two pizzas, why would the denominator still be the same sometimes? (I said sometimes)
• If you slice up a pizza into eight slices, and eat one slice, you have eaten 1/8 of the pizza. If you eat another piece, you will have eaten 2/8 of the pizza.

If you slice up two pizzas, you will have sixteen slices. Eat one slice and you will have eaten 1/16 of the two pizzas. If you eat another slice, you will have eaten 2/16 of the two pizzas.

I hope this helps you understand how the denominator can remain the same.
