Dividing Fractions

Opening: Last class was spent reviewing the idea behind common denominators. Today, we will begin with a short assessment on this topic.

Objectives:
  • I will use models to represent division of fractions.
  • Return to estimation - what skills am I using when estimating?

Estimating: How many sheets of toilet paper are on the roll?


Two Scenarios - whiteboard it!

A) Sally has 12 marbles and she wants to give 3 to each friend. To how many friends can she give her marbles?


b) Sally has 12 marbles and she wants to distribute them among three friends. How many marbles will she give to each friend?


To do:
  1. Draw a diagram that shows each scenario.
  2. What do the two scenarios have in common?
  3. What is different about the two scenarios?
