Fraction Flags!

Introduction

Fractions, fractions everywhere! What is a fraction you may ask?

A fraction is a smaller part of a whole. For example, a whole pizza cut into slices, or sharing a box of Smarties among friends. 

Watch the video below to understand how we use fractions in every day life!

 

Math Strands:

B1.3: "Represent equivalent fractions from halves to twelfths, including improper fractions and mixed numbers, using appropriate tools, in various contexts" (MOE, 2020).

B1.4: "Compare and order fractions from halves to twelfths, including improper fractions and mixed numbers, in various contexts" (MOE, 2020). 

Task

Students will participate in the following activities in order to complete the Webquest assignment.

1) Review equivalent fractions by watching a video and completing a quiz. 

2) Watch videos related to Whole Numbers Minus a Fraction and Partitioning a Whole. 

3) Represent equivalent fractions using classroom materials and items found around their home, on the web and/or in the community. Demonstrate their knowledge by designing a fraction flag to represent their class. 

Process

1) Review equivalent fractions

Listen to the video linked below about equivalent fractions, and complete the multiple choice questions embedded in it.

2) Design a Class Flag

Guidelines for the flag include:

The flag must be a rectangle.

It must have 4 different sections on it:

  • 3/10 is striped
  • 1/4 is a solid color
  • 1/5 is a pattern of your choice
  • The remainder is photo/clip art/drawing of your choice

Draw the flag on a grid paper or construct it using Google Slides.

a) Consider the fractions of the 4 different sections of your flag 3/10 is striped, 1/4 is a solid color, 1/5 is a pattern of your choice and the remainder fraction is photo/clip art/drawing of your choice. 

b) Figure out remaining fraction space for the photo/clip art/drawing of your choice. For this, you might need to review how to minus a fraction from a whole number linked here: 

 

c) Use what you know about equivalent fractions to make dominators of all the fractions the same. 

d) Next, review the lesson below on creating equal partitions of shapes.

 

 

Part 2:

Come up with your own different guidelines to design a flag. Make sure your guidelines include sections that will cover the entire flag.

You should use different fractions than the ones used in part 1.

Flag Creation

 

 
  • 3/10 is striped
  • 1/4 is solid colour
  • 1/5 is pattern of your choice
  • remainder is photo/clipart/drawing and fraction is correct
  • fractions are all correct and add up to 1
  • flag is created by hand with a ruler and pencil crayons or using Google Slides
 
Flag Guidelines  
  • guidelines are clear and make sense
  • fractions all add up to 1
  • fractions are different than those used in student's own flag
  • guidelines show understanding of equivalent fractions
 

   

Conclusion

By the end of this lesson, you should have a good understanding of equivalent fractions. As well, you should be able to compare and represent various fractions that add up to a whole. Your class flag is a great representation of your understanding of these concepts.  For further practice, here are a few games and websites to check out:

Teacher Page

This lesson and assignment was created for Grade 5 Mathematics. 

Students can work through the webquest videos with a partner. The flag should be completed independently. 

Prerequisite skills from Grade 4 include the following:

B1.4 "Represent fractions from halves to tenths....and explain the meanings of the denominator and the numerator" (MOE, 2020)

B1.5 "Use drawings and models to represent, compare, and order fractions representing the individual portions that result from two different fair-share scenarios involving any combination of 2, 3, 4, 5, 6, 8, and 10 sharers" (MOE, 2020)

B1.6 "Count to 10 by halves, thirds, fourths, fifths, sixths, eighths, and tenths, with and without the use of tools" (MOE, 2020)
