Unit 6, Lesson 3-- Building Fractions

Lesson 3-- Building Fractions

Introduction

Hello Mathematicians! Today we will be learning about building non-unit fractions.

Take a look at image A and image B.  What is the same?  What is different?  Jot down your thoughts in your math notebook.

Directions:

• Let's experiment with fractions in the lab again today.
• Using the interactive, navigate to the Fraction: Intro Lab.  

• Build a non-example of a unit fraction.  Remember, a unit fraction is a fraction with 1 in the numerator.  It is one piece of a whole. A non-unit fraction is made by combining two or more unit fractions.  It would be a fraction with a numerator other than 1.

  • What do you observe when you make the numerator a number other than 1?

  • Draw and label 3 non- unit fractions in your notebook.

In Your Math Notebook:

Let’s get out our math notebook and  work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write an answer with numbers and words.

Read, Draw, Write, DONE!

R (Read the problem carefully.) Ellie makes a triangle with Play- Doh.  Her little sister comes along and takes one fourth of it.  How much of the Play-Doh does Ellie have left? D (Draw a picture.) W (Write an answer with numbers and words.)
