General Lesson Information
 Lesson Plan ID: 26357 Title: I Want My Half- An Interactive Lesson Introducing Fractions Overview/Annotation: In this lesson, the children will identify parts of a whole using modeling clay, participate in an interactive web lesson, participate in an interactive web game, and construct a fraction poster. The activities are used as instructional plans to help students better understand shapes and parts of a shape up to a whole.This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Associated Standards and Objectives
Content Standard(s):
 MA2015 (1) 21. Partition circles and rectangles into two and four equal shares; describe the shares using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares. [1-G3] ELA2015 (1) 29. Participate in shared research and writing projects (e.g., explore a number of "how-to" books on a given topic and use them to write a sequence of instructions). [W.1.7] ELA2015 (1) 40. With guidance and support from adults, demonstrate understanding of word relationships and nuances in word meanings. [L.1.5] a. Sort words into categories (e.g., colors, clothing) to gain a sense of the concepts the categories represent. [L.1.5a] b. Define words by category and by one or more key attributes (e.g., a duck is a bird that swims; a tiger is a large cat with stripes). [L.1.5b] c. Identify real-life connections between words and their use (e.g., note places at home that are cozy). [L.1.5c] d. Distinguish shades of meaning among verbs differing in manner (e.g., look, peek, glance, stare, glare, scowl) and adjectives differing in intensity (e.g., large, gigantic) by defining or choosing them or by acting out the meanings. [L.1.5d]

Local/National Standards:

Alabama Course of Study MA2009 (5) Identify parts of a whole with two, three, or four equal parts.

NCTM Numbers and Operations (K-2): Understand numbers, ways of representing numbers, relationships among numbers, and number systems - understand and represent commonly used fractions, such as 1/4, 1/3, and 1/2.

Primary Learning Objective(s):

Students will identify equal parts of a whole.
Students will divide shapes into equal parts.

Students will create shapes showing equal parts.

Preparation Information
 Total Duration: 61 to 90 Minutes Materials and Resources: Eating Fractions, by Bruce McMillanRed, yellow, and brown modeling clay for each pair of studentsPlastic knife for each pair of students3 plastic zip close bags for each pair of studentsFraction recording sheet for each studentScissorsConstruction paper shape cut outs (Each student will need a variety of shapes-circles, squares, triangles, rectangles to cut into the different fractions.)Large sheet of construction paper for each child Technology Resources Needed: Computer with Internet acccessProjector connected to computerI Want My Half Interactive Web LessonCross The River Interactive Web GameFractions Interactive Web Game Background/Preparation: Prior to the lesson, roll the yellow modeling clay into a cylinder shape. It will resemble an ear of corn. Place the yellow modeling clay in separate zip close bags for each pair of students. Roll the brown modeling clay into a pie or circle shape. It should resemble a muffin. Place the brown modeling clay in separate zip close bags for each pair of students. Roll the red modeling clay into a pie or circle shape. It should resemble a pie. Place the red modeling clay in separate zip close bags for each pair of students.Assign students a heterogenous discussion partner that they will sit with during the engage portion of the lesson. Have students return to their desks during the explore part of the lesson. It might be helpful to have them continue working with their partner.The book, Eating Fractions, shows different food cut into fractions. For example, it shows an ear of corn cut in half.Students will place their fraction recording sheet and their fraction poster in their math journals.
Procedures/Activities:
 Engage Step 1:  Explain to the students that you have one sandwich, but you want to share it with a friend.  Ask the students if they can figure out a way to share your sandwich with your friend and both of you have equal parts.  Have students turn and talk with a partner to help you solve your problem.  Give students time to discuss.  Select a pair of students to share with the rest of the class. Step 2: Explain to students that during this lesson they will learn to identify parts of a whole with two, three, or four equal parts. Step 3: Read Eating Fractions, by Bruce McMillan. Stop on each page and discuss with students what the picture shows. Explore Step 1: Hand out the bags of clay and plastic knife.  Have students locate the bag with the yellow modeling clay.  They will work with their partner to discover a way to cut the yellow modeling clay role into two equal parts.  The teacher will walk around the room and observe the students working cooperatively.  The teacher will also observe each group dividing the clay shape into half (see assessment rubric, Identifying Fractions).  Once the teacher has observed the students successfully dividing the shape into half, the teacher will have the students journal their answer by drawing a picture of their answer on the fraction recording sheet.  Then the teacher will challenge the students to find another way to cut the shape into two equal parts.  Give students time to explore the different ways they can divide the shape into 2 equal parts. **Have a copy of the book Eating Fractions for students to refer to if they are having a problem.** Step 2.  Repeat the same procedure with the brown modeling  clay.  This time the students are dividing the shape into three equal parts.  Remind the students to journal their answer.  Once again, challenge the students to figure out a different way to divide the shape into 3 equal parts. Step 3: Repeat the same procedure with the red modeling clay.  This time the students are dividing the shape into four equal parts.  Remind the students to journal their answer.  Once again, challenge the students to figure out a different way to divide the shape into 4 equal parts. Explain  Step 1:  Have students meet back as a whole group.  Ask students if the pictures they drew reminded them of any they saw in the book Eating Fractions.  Show the students the pictures from the book and discuss how each picture is divided into equal parts.  Have selective students demonstrate how they divided their modeling clay into halves, thirds, and fourths.  Encourage students to use the fraction vocabulary in their descriptions. Step 2:  Watch I Want My Half.  Choose different students to complete the interactive activities within the lesson.   Extend As an extension activity, the students will make a fraction poster.  They will label the large sheet of construction paper with 1/2, 1/3, 1/4.  They will take the construction paper shapes and cut them into halves, thirds, and fourths and glue them under the correct label. As an extension activity, the students will complete the interactive game, Cross The River. Evaluate As the students are completing the activities, teacher will use the Identifying Fractions rubric to assess student understanding of fraction identification.

Assessment
 Assessment Strategies As the students are completing the activities, teacher will use the Identifying Fractions rubric (attached) to assess student understanding of fraction identification.
 Acceleration: Intervention: For students who need extra practice identifying fractions or those who have problems cutting the shapes into equal parts, have them work through the interactive web game Fractions.
