Title: LESSON 8: Dividing Fractions
Lesson Overview: Students will learn how to divide proper, improper, and mixed fractions.
Resources or Materials Needed:
Teachers: Activboard Division Lesson and Jeopardy game, computer, Elmo (document camera), example division foldable
Students: math toolkit, individual whiteboard, marker and eraser, blank paper for notes, student worksheet, scissors, markers, foldable, post-test
Technology: Prezi Presention, class blog, Mastery Connect
Lesson Standards:
USOE Mathematics Fifth Grade Number and Operations Fractions 3:
Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem
Lesson Objectives:
Performance Objective 8: When given a math worksheet of 10 fraction equations, including proper, improper, and mixed fractions, involving division, students will correctly solve, without a calculator, with 80% accuracy.
Performance Objective 9: When given a math worksheet of 10 fraction equations, including proper, improper, and mixed fractions, involving division, students will correctly solve, with a calculator, with 80% accuracy.
Time: Approximately 1 ½ hours

Step 1: Pre-instructional activities:
· Students will get out their math toolkits
· Teacher will pass out Dividing Fractions foldables
· Teacher will put example on Elmo and explain as students copy down information
o Foldable will include all the steps to dividing fractions
§ 1. Turn the second fraction (the one you want to divide by) upside-down (this is now the reciprocal)
§ 2. Multiply the first fraction by that reciprocal
§ 3. Simplify the fraction (if needed)
o Students will add reciprocal to their vocabulary list, with definition
· Teacher will put a few basic dividing equations on the board as review
· Students will glue in foldable and division practice paper
· Students will get out their math toolkits
· Teacher will pass out Dividing Fractions foldables
· Teacher will put example on Elmo and explain as students copy down information

Step 2: Content presentation:
· Teacher will open Prezi Dividing Fractions on ActivBoard (or they can use the Dividing Fractions PowerPoint)
· Students will get out a piece of paper and take notes on the presentation
· Teacher will explain that when we divide fractions, it is a multi-step process
§ 1. Turn the second fraction (the one you want to divide by) upside-down (this is now the reciprocal)
§ 2. Multiply the first fraction by that reciprocal
§ 3. Simplify the fraction (if needed)
o The lesson will also include that when we divide mixed fractions, you keep the whole number and just deal with the fractions
· After guided notes, teacher will go to class blog and open http://www.mathsisfun.com/fractions_division.html to reinforce the dividing fractions concept
· Students will verbally answer questions as teacher goes through the website

Step 3: Learner Participation:
· Same activity as multiplying fractions
o Students will use their whiteboards and markers
o Teacher will put a division equation on the board
o Students will copy down the problem on their whiteboard and solve, when they have finished they will hold up their white board
o If they get it correct they get 2 points
o If they get it incorrect, they have a chance to fix it and get 1 point
