Grade Level:

4/5
Timeframe:
One Week

50 Minute Class Periods

5 Class Periods


Lesson Description or Explanation

These lessons will be taught in five day duration. During these times students will:
Differentiate between fractions as whole, parts, or sets
Add and subtract fractions with different denominators
Understand fractions as a part whole concept
The students will be using the computer to help solve the different mathematical applications and be able to come to a conceptual understanding of fractions.

Indiana Curricular Standards


5.1.5 Explain different interpretations of fractions: as whole, parts or a set , and division of whole numbers by whole numbers.

5.2.2 Add and subtract fractions (including mixed numbers) with different denominators.



ISTE Standards


2. Design and Develop Digital-Age Learning Experiences and Assessments

Teachers design, develop, and evaluate authentic learning experiences and assessments incorporating contemporary tools and resources to
maximize content learning in context and to develop the knowledge, skills, and attitudes identified in the NETS.

a. design or adapt relevant learning experiences that incorporate digital tools and resources to promote student learning and creativity.

b. develop technology-enriched learning environments that enable all students to pursue their individual curiosities and become
active participants in setting their own educational goals, managing their own learning, and assessing their own progress.

c. customize and personalize learning activities to address students’ diverse learning styles, working strategies, and abilities using
digital tools and resources.

d. provide students with multiple and varied formative and summative assessments aligned with content and technology.

Assessments
Formative/Summative

Summative: Students will do “Fraction Bars” ( on computer http://arcytech.org/java/fractions/), and show answers to teacher. Teacher will walk around with a clipboard and check off for completion and understanding. Students who do still not understand fractions will have small group instruction. We will also be walking around the room, while activities are going on, to assess growth. We will have whole group discussions and reflect on concepts and strategies that are being constructed

Formative: On the fifth day students will create their own pizza based on fractions from materials in the classroom (construction paper ect.).

Prior Knowledge

Curricular Knowledge or Skills: Fractions; addition and subtraction of fractions, multiplication, division.

Procedure

Day 1: We will examine prior knowledge of fractions as a part-whole concept. Students will express their knowledge through the “Think, Pair, Share” strategy. After sharing, we will collaboratively, as a whole class, come up with an understanding of fractions as a part-whole concept, which will be transferred onto a classroom chart.

Day 2: This day will consist of students exploring fractions with the “Fraction Bar” website. Students will work independently. Throughout the lesson students will be asked to represent multiple fractions using the tools provided. Once students have had practice and completed multiple fraction bars, we (the teachers and aids) will assess their current understandings.

Day 3: Students will revisit “Think, Pair, Share” strategy of fractions and share new understandings with the class. We will add these new connections to the classroom chart.
They may also be given additional independent work time for small group instruction and or one-on-one time.

Day 4: Students will visit “pizza fraction” website activity. This interactive website provides students with measured ingredients for toppings. The students will be given “pizza orders” to complete using the fractions. We will be concentrating on multiple fractions combining for the whole.

Day 5: “Pizza Day”! Students will create own specialty pizzas (materials will be provided). They will be given a pizza order with multiple fractions listed to complete the pizza order as a whole. We will come back as a group to discuss the different processes the students applied to complete their pizza order. New understandings and strategies will be added to the classroom chart.
Differentiated Instruction

ESL
Students will have the option to have the entire website translated into a more familiar language. If they chose to do so they may have the option to work with a partner.

Challenge/Extend

· To challenge students, they may be given mixed fraction “toppings” to create their pizza.
· They will represent serving sizes specific to a group. This will be represented as a fraction.

Special Needs

· Students will have the lesson differentiated according to their IEP.
· The in classroom special education aid will be available to assist students.

Specific examples can include:
· Additional time to be given.
· Students may be given readymade “pizzas” and asked to shade in the different “toppings” for students that may have trouble with their fine motor skills.
· Students who have difficulty using the computer may be taught in small group or one on one instruction. Additional manipulatives will be supplied.
· Students with special needs may work in pairs.
