Objective: Students will compare and order fractions. November 4, 2009 Math 201 Objective: Students will compare and order fractions. Aim: How do we use models to compare fractions, and how can we use our knowledge of the lowest common denominator to help us order fractions? Prior knowledge: 2/5 + 3/10 = ?

Mini – lesson:

Order from least to greatest: 3/8 2/3 2/4 3/8 2/3 2/4 Step 1. List the multiples Step 2. Find the Least Common Multiple, which is the lowest common denominator Step 3. Make equivalent fractions with the new denominator Step 3. Order from the smallest value to the largest value

Try another! Order from greatest to least: 5/8 4/6 7/12 Homework: Order from least to greatest: 2/3 5/9 5/6 11/18 3/4
