Unit 6, Lesson 15-- Fractions Greater than One

Lesson 15-- Fractions Greater than One

Introduction

Hello Mathematicians! Today we will be learning about fractions that are greater than one whole.

Take a look at this image of leftover pizza.  How could we represent this amount with a fraction?  Jot down your thoughts in your notebook.

Part 1 Directions:

  • In today's math lab, you will experiment with mixed numbers and improper fractions.
    • Open the Fractions: Mixed Numbers Intro Lab.
      • Change the "max" arrow at the top to 2, 3, or 4.
      • Use the yellow arrows to change the numerator and denominator of the fraction you are building. 
      • Change the model type at the top of the interactive (pie/ circle model; bar models; cylinder model; cake model; line/ ruler model).
    • Build 3 fractions whose numerators are larger than the denominator. Show them in your math notebook using drawings, numbers, or words.

Part 2 Directions:

  • Complete the chart below in your math notebook. 
  • Each row of the chart contains various representations of the same fraction, but some are missing for you to fill in.  For example, the first row shows you the number 1 1/4 (one and one-fourth) as a circle/ pie model.  Your job is to fill out the missing fraction bar model, number line, and improper fraction.
  • Use the interactive to help you build, draw, and name the models.
