Title: LESSON 5: Proper and Improper Fractions with Different Denominators
Lesson Overview: Students will learn how to find Greatest Common Factors (GCF) and Least Common Multiples (LCM) for proper, improper, and mixed fractions with different denominators
Resources or Materials Needed:
Teachers: GCF and LCM Lesson on Activboard, computer, Elmo (document camera), example of GCF and LCM foldable
Students: math toolkit, individual whiteboard, marker and eraser, student worksheet, scissors, markers, foldable for GCF and LCM
Technology: class blog, Photoshop
Lesson Standards:
USOE Mathematics Fifth Grade Number and Operations 1:
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.
Time: Approximately 1 hour

Step 1: Pre-instructional activities:
· Students will get out math toolkits
· Students will need scissors, markers, and glue
· Teacher will pass out GCF and LCM Foldables
o Example at (open from class blog): http://simplifyingradicals2.blogspot.com/2013/09/gcf-and-lcm-foldable.html
· Students will follow along as teacher goes over the steps needed to build the foldable
· The top half will teach GCF, the bottom half will cover LCM
· Students will copy the information then glue into math toolkit
Teacher will have used Photoshop for Foldable
· Students will get out math toolkits
· Students will need scissors, markers, and glue
· Teacher will pass out GCF and LCM Foldables

Step 2: Content presentation:
· Teacher will pass out guided notes with a Venn diagram on the front for GCF and written notes on the back for LCM
· Teacher will open ActivBoard lesson Greatest Common Factor
· Students will write and follow along as teacher goes step by step through greatest common factor Venn diagram lesson
· Students will then turn their paper over for a lesson on Least Common Multiple
