LEARNING ACTIVITY #2
COMPARING FRACTIONS
Let's begin by getting into the same pairs as we were in yesterday! I am going to pass out the same fraction plates that we used yesterday.
- Each pair needs to pick ONE person to show an EQUIVALENT FRACTION using the 1/2 plate with any other plate of your choice.
- Switch roles and have the other person show an equivalent fraction using the 1/3 plate with any other plate of their choice.

Higher Order Thinking!!
- Is everything in life equal?
- Are all the people in the world an equal height?
- Is everyone's pencil today an equal length?
- Can you name some other things that you know of that are not equal?
- Do you think all fractions are equal?
Yesterday, we talked about how we could use different fractions plates to create EQUIVALENT (______) FRACTIONS! Today we are going to discover more about fractions and how to COMPARE them!
We need some RULES FOR COMPARING FRACTIONS!!!
Before we start comparing fractions, let's come up with some simple rules that will help us understand a little more about fractions and how they work!
1st: Look at the plate that is divided into 2 parts.
2nd: Which plate is that? ____
3rd: How many parts is that plate divided into? _____
4th: If we were going to separate this fraction plate into groups, how many groups (sets) would we have? _____
Remember, the denominator determines how many groups or sets we can make from our fraction!!!
5th: Now let's look at the plate that is divided into 4 parts.
6th: Which plate is that? ______
7th: How many parts is that plate divided into? ______
8th: If we were going to separate this fraction plate into groups, how many groups (sets) would we have? ______
Remember, the denominator determines how many groups or sets we can make from our fraction!!!!
Important: The bigger the number in the denominator – the more parts there are to the fraction plate and the smaller each part is. Therefore, it takes more pieces on a fraction plate with a big denominator to equal the same fraction on a fraction plate with a smaller denominator.
1st: Look at the plate that is divided into 2 parts.

Learning Activity #2
Problem #1
Based on what we just learned, can you solve this problem?
Brad’s mom ordered two pizzas from the pizzeria. She asked that 1 pizza be cut into 4 pieces and the other pizza be divided into 8 pieces. When the pizzas arrived, she gave Brad 1 piece from the pizza that was divided into 4 pieces and Brad’s sister 1 piece from the pizza that was divided into 8 pieces. Who got the bigger piece of pizza? How do you know? Use your fraction plates if you need help solving this problem.

Rule #1
- If the numerators of the two fractions that we are comparing are the same, the fraction with the smaller number in the denominator always represents the bigger (greater) fraction.

- If the denominators of the two fractions that we are comparing are the same, the fraction with the larger number in the numerator always represents the bigger (greater) fraction.
Comparing Rules YOU NEED TO KNOW!!!!
Rule #1 - If the numerators of the two fractions that we are comparing are the same, the fraction with the smaller number in the denominator always represents the bigger (greater) fraction.
Rule #2 - If the denominators of the two fractions that we are comparing are the same, the fraction with the larger number in the numerator always represents the bigger (greater) fraction.
Now for the TOUGH PART!!!!
- What happens when neither the numerator or the denominator are the same? We are going to use our plates today in a different way to help us discover the answer!
2nd: Show 1/3 on your first fraction plate and 1/2 on your second fraction plate.
3rd: Put the plates side by side and compare the two fractions. Tell me what you notice.
4th: Could we use a rule to help us solve this problem if we didn't have fraction plates? Which rule could we use?
- Let's try another one using the 1/8 and 1/5 fraction plates.1st: Show 5/8 and 2/5 on your fraction plates.
3rd: Put the plates side by side and compare the two fractions. Tell me what you notice.
4th: If we wanted to compare these two fractions, what math symbols could we use?
Application Time.....
Now you are going to work with your partner. Using the fraction plates, you and your partner are going to complete the worksheet: Dare to Compare. By using your Comparing Rules and fraction plates, you will be comparing sets of fractions and deciding whether the fraction on the left of set is greater that, less than, or equal to the fraction on the right. If you can use a rule to solve a comparison, write either Rule #1 or Rule #2 beside the problem that explains the rule you used.
-Extension: Give the student the opportunity to create his/her own flash cards. They can use these flashcards to create a game of “comparison fraction war” with their classmates.

- What strategies could we use?
- Could we use multiplication?
Multiplication to Find Equivalent Fractions
It's GAME TIME
I am going to pass back out the fraction paper plates. However, before you actually begin to order (sequence) fractions, you need to remember that fractions actually represent numbers that are _________ than one __________.
In order to help you arrive at the above conclusion, I am going to draw a number line on the board with only the 0 labeled at the beginning (left hand side) and a blank line at the end of the number line (right hand side) where another number needs to be written.
In order to help you arrive at the above conclusion, I am going to draw a number line on the board with only the 0 labeled at the beginning (left hand side) and a blank line at the end of the number line (right hand side) where another number needs to be written.
- If you were creating a fraction number line, what is the greatest number you should use? (Remember a fraction actually represents (part of one whole).
- What other number should we place on the number line in order to make our number line easier to read? Should that number be a whole number or a fraction? (You may use your fraction plates to make your decisions!
- Is 2/3 > 1/2?
- Is 2/3 > 1 ?
- What do we know then about where the fraction 2/3 should go on the number line?
- How can we use the number line, fraction plates, and multiplication strategies to compare our fractions to 1/2 in order to place them onto the number line correctly between 0 and 1?
TEST TIME!!!!!
I am going to place the Hershey's Milk Chocolate Fraction Book "guess" sheet back on the board. (Remember we completed this during Learning Activity #1). I am now going to pass out the FRACTION CLOTHESLINE worksheet.
Now that we have explored fractions for three days, we are going to put our fraction smarts to work and use the Hershey Fractions Book guess sheet and our fraction plate to put the fractions on the cover of the book in order from least to greatest.
-Extension: Give the student the opportunity to add fraction clothes to their clothesline.
- Remember that guess list was generated at the beginning of class during learning activity #1. Why am I referencing that fact? Why is that important?
Now that we have explored fractions for three days, we are going to put our fraction smarts to work and use the Hershey Fractions Book guess sheet and our fraction plate to put the fractions on the cover of the book in order from least to greatest.
- What other strategies could we use to order the fractions?
-Extension: Give the student the opportunity to add fraction clothes to their clothesline.
Do you think you can pass the test now?????
Embedded Assessment – After you have completed your clothesline, I will pass out the Fraction “Clothes” worksheet to be completed independently by each of you. This resource sheet is designed to allow you to apply your cumulative knowledge and show acquired knowledge of fractions.
