Title: LESSON 6: Comparing Fractions with different denominators
Lesson Overview: Students will learn how to compare proper, improper, and mixed fractions with different denominators. They will learn how to determine which fraction is greater than, less than, or equal to.
Resources or Materials Needed:
Teachers: Activboard Comparing Fractions Lesson, computer, Elmo (document camera), example comparing fractions foldable
Students: math toolkit, individual whiteboard, marker and eraser, student worksheets, scissors, markers, foldable, clickers
Technology: clickers
Lesson Standards:
USOE Mathematics Fourth Grade Number and Operations 2:
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
Lesson Objectives:
Performance Objective 5: When given a math worksheet of 10 fractions, including proper, improper, and mixed fractions, students will correctly compare two fractions with 80% accuracy.
Time: Approximately 1 hour

Step 1: Pre-instructional activities:
· Students will get out their math toolkits, scissors, markers, and glue
· They will turn to the entry on comparing proper fractions – they will review what greater than, less than, and equal too mean
· They will receive a blank paper to make a foldable for “Comparing Fractions with Different Denominators”
· Teacher will put foldable example on ELMO
· Students will copy example
· Teacher will discuss the similarities with comparing proper fractions with the same denominator
· Students will get out their math toolkits, scissors, markers, and glue

Step 2: Content presentation:
· Teacher will open “Comparing Fractions with Different Denominators” on ActivBoard
· Students will be given guided notes to follow along
· The presentation will begin with visual representations with shaded shapes, then slowly move into written fractions by themselves
· Teacher will explain how to change the denominators so that they are the same number
· Teacher will open “Comparing Fractions with Different Denominators” on ActivBoard
· Students will be given guided notes to follow along
· The presentation will begin with visual representations with shaded shapes, then slowly move into written fractions by themselves
· Teacher will explain how to change the denominators so that they are the same number

Step 3: Learner Participation:
· Teacher will bring out Bubble Clickers (or bell if clickers are not available)
· Students will be separated into two teams
· Teacher will put a comparing fractions with either like denominators and different denominators question on the board
· Students will need to solve in their teams, when they have the correct answer they will send a person up to ring the bell
· Teacher will bring out Bubble Clickers (or bell if clickers are not available)

Step 5: Follow-through activities:
· Students will get in pairs and play “Fraction Wars”
· This game involves students having two stacks on Fraction Cards
· Each card will have a different fraction, some with picture, some with written fractions
· Students will need to determine if they hold the greater fraction, least fraction, and equal fraction
