Cut, Draw, and Write Fractions
Cut, Draw, and Write Fractions! | |
|Grade Level: Third Grade |
|Assessment: Ask your student to draw 1 whole and label it using a sheet of blank paper and a writing utensil. Repeat this with 1/3,|
|1/5, 1/2, and 1/4. |
|Alignment/ Standards: |
| |
|Pennsylvania Department of Education State Aligned Standards |
|M3.A.1.2.1: Write the fraction that corresponds to a drawing or part of a set (numerators 1-9, denominators 2-10. No equivalent or |
|improper fractions or mixed numbers). |
|M3.A.1.2.2: Create a drawing or set that represents a given fraction (numerators 1-9, denominators 2-10. No equivalent or improper |
|fractions or mixed numbers). |
| |
|Common Core Standards |
|CCSS.Math.Content.3.NF.A.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal |
|parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. |
|Vocabulary: |
|Fraction- Any part of a group, number, or whole. |
|Numerator- The number above the line of a fraction, showing number of parts of a whole. |
|Denominator- The bottom of a fraction. The number of groups the whole is divided into. |
|Objectives: |
|The student will be able to draw a picture to represent a fraction correctly 4 out of 5. |
|The student will be able to write a fraction to represent a picture. |
|Essential Question: |
|How can we represent fractions? |
|Duration: |
|~15 minutes |
|Materials: |
|Paper cut into 6 equal sized circles or 6 paper plates |
|Crayons, markers, or colored pencils |
|Scissors |
|2 blank pieces of paper |
|Suggested Instructional Strategies: |
|Active Engagement- The student is coloring, cutting, and drawing fractions. |
|Modeling- The teacher models the first fraction so the student can observe the activity. |
|Skill/Concept- Throughout the lesson the students will be |
|Kinesthetic/Tactile- The students are able to physically color, create, and represent fractions. |
|Analysis- The students analyze characteristics of fractions and determine |
|Instructional Procedures: |
|Introduction |
|Today we are going practice representing fractions in different ways. We will color, write, and even cut fractions. But first, |
|let’s review what we know about fractions. When we make a whole into fractions, we need to separate it into equal pieces. When we |
|write fractions we place the numerator or the number of parts of a whole on the top and the denominator, the number of groups the |
|whole is divided into. Let’s make some fractions! |
|Have your student color each paper plate to look like a different circular object. (ex. Beach ball, pumpkin, cookie, wheel, etc.) |
|Pick one of the colored circles and a piece of paper and writing utensil. |
|Say, this is one whole paper plate. I am going to draw a picture on this paper of 1 whole and next to my picture I am going to |
|write 1 because it is one whole. |
|Repeat this process with another plate and cut it into half. Say, “This is cut into halves. I am going to draw a picture of this |
|circle and next to each piece I am going to write ½.” |
|Now it is your turn! Have students cut one of their circles into thirds, draw it, and label each piece. |
|Continue this with the last three circles, fourths, fifths and sixths allowing the student complete fifths and sixths |
|independently. |
|Conclusion: How many ways did we represent fractions? What do you think we do more often, draw or write fractions? Why? We cut, |
|wrote, and drew fractions. Let’s see if you can represent fractions without the plates. |
|Assessment: Ask your student to draw 1 whole and label it using a sheet of blank paper and a writing utensil. Repeat this with 1/3,|
|1/5, 1/2, and 1/4. |
|Modifications/ Extensions: |
| |
|Extension- See how many different ways you can cover the whole circle with the fraction pieces (ex. 1/2 and 2/4s = 1 whole). Keep a|
|record of your combinations. This can even be competitive. See who can find the most combinations to make 1 whole. |
|Retention- If the student is struggling with drawing fractional representations, the student can trace the fraction pieces of |
|plates onto a blank piece of paper and label them. |
