Showing Fractional Amounts Greater Than 1; Writing Mixed Numbers Today you will learn how to show fractional amounts greater than 1 and how to write mixed numbers.
Showing Fractional Amounts Greater Than 1; Writing Mixed Numbers • mixed number
A few weeks ago we used pattern block to show fractions. We pretended that the pattern blocks were pieces of cake. What fractional part of the cake was the red trapezoid? 1/2 What fractional part of the cake 1/3 was the blue parallelogram? What fractional part of the cake was the green triangle? 1/6
How much cake will we have if we have 2 red trapezoids? 1 whole cake How much cake will we have if we have 3 red trapezoids? 1 and 1/2 cakes We have one whole cake plus one half more. We write one and one half like this: 1 1 2 This means that we have one whole cake plus another half of a cake. When we write 1 1 we do not need to write a plus sign 2 between the 1 and the 1/2.
How much cake will we have if we have 4 red trapezoids? 2 cakes How much cake will we have if we have 5 red trapezoids? 2 and 1/2 cakes We have two whole cake plus one half more. We write two and one half like this: 2 1 2
What fractional part of the cake was the blue parallelogram? 1/3 How much cake will we have if we have 2 blue parallelograms? 2/3 of a cake How much cake will we have if we have 3 blue parallelograms? 1 whole cake
How much cake will we have if we have 4 blue parallelograms? 1 and 1/3 cakes We have one whole cake plus one third more. We write one and one third like this: 1 1 3 This means that we have one whole cake plus another third of a cake.
How much cake will we have if we have 5 blue parallelograms? 1 and 2/3 cakes 2 How do you think we will write this? 1 3
All of the numbers we have been talking about are mixed numbers. 2 1/2, 1 1/3, 1 2/3 They have a whole number plus a fraction. The whole numbers are the numbers that we say when we count by 1’s from zero. What are the whole numbers in the problems we have been talking about? 1 and 2 What are the fraction in the problems we have 1/2, 1/3, and 2/3 been talking about?
Now everyone will have a chance to show fractional amounts greater than 1. We will use pattern blocks to do this. I was very hungry and I ate one and one-half cakes. Use the pattern block to show much cake I ate. How do you think we will write how much cake I ate? 1 1 2
Brian, the custodian, was very hungry and ate two and one-third cakes. Use the pattern block to show much cake Brian ate. How do you think we will write how much cake Brian ate? 1 23
Mr. Shelley, the principal, was hungry and ate one and one-sixth cakes. Use the pattern block to show much cake Mr. Shelley ate. How do you think we will write how much cake Mr. Shelley ate? 1 1 6
2 23 This is how much cake you ate. Show this using pattern blocks.
1 5 6 This is how much your sister ate. Show this using pattern blocks. Put your pattern blocks back in the bag.
How much cake is shaded 1 1/3 in Problem 1? How much cake is shaded 2 1/6 in Problem 2? How much cake is shaded 3 1/2 in Problem 3? How much cake is shaded 1 2/3 in Problem 4? How many equal pieces 4 are in the candy bar? What fractional part is 1/4 each piece? Write a mixed number to show many candy bars Sam ate. 1 1/3 2 1/6 1/4 3 1/2 1 2/3 4 2 1/4
Write a mixed number to show many candy bars Gail ate. Write a mixed number to show many candy bars Max ate. How many whole candy bars and extra pieces will you color to show many candy bars Sherry ate? One whole candy bar plus one extra piece. Color the candy bars to show this. 1 1/3 2 1/6 1/4 3 1/2 1 2/3 4 2 1/4 1 3/4 2 2/4
How many whole candy bars and extra pieces will you color to show many candy bars David ate? One whole candy bar plus 3 extra pieces. Color the candy bars to show this. How many whole candy bars and extra pieces will you color to show many candy bars Doug ate? One whole candy bar plus 2 extra pieces. Color the candy bars to show this. 1 1/3 2 1/6 1/4 3 1/2 1 2/3 4 2 1/4 1 3/4 2 2/4
