This Lesson Plan is based on the Standard MAFS.4.NF.1.1: Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions
This lesson focuses on creating equivalent fractions using the numbers 2, 3, and 4. Students will practice multiplying the numerator and the denominator by 2, 3, or 4 to create equivalent fractions.

 Lesson Plan Template: General Lesson Plan

Formative Assessment
Recognizing Equivalent fractions:
 The teacher will ask students to prepare for their warm up, which will be posted on the walls of the room.
 The teacher will post fractions around the room on printer paper, large enough to be seen anywhere in the room. The fractions will be: 1/2, 2/3, 2/6, 3/4, 1/4, 1/5
 The teacher will write a fraction on the board and ask students to stand next to the fraction that they think is equivalent to that fraction.
 Students may use their scrap paper to find answers.
 After each student has chosen, the teacher will select a student(s) to explain why their answer is correct. Continue giving fractions until all students have given an explanation or gotten several incorrect. Make sure to ask if students have different explanations for the correct answers. Examples of fractions the teacher can give are: 2/10, 4/8, 3/6, 2/8, 4/6, 5/10
 The teacher will record observations about what each student is able to accomplish on a Role Sheet. (Role Sheets have each students name listed with boxes beside each with room to record student responses. Spaces for dates should be available also).
 Students would score 0 for no understanding or being unable to explain their answer.
 Students would score 1 for correct answers and explanations.

Feedback to Students
 During the formative assessment, students are required to explain their thinking or reasoning for the answers they chose.
 There are multiple times during teaching phase and guided practice for students to ask questions and the teacher to provide feedback.
 During guided practice, there are stopping points to allow for questions.

Summative Assessment
 Students will be given 5 groups of 2 fractions. For each problem, using the multiplication method taught during this lesson, students must determine if the fractions are equivalent or not. Students should be able to find the number used to multiply and create the equivalent fraction and they can only use 2, 3, or 4.
 Students will record their responses on notebook paper and turn in to the teacher. Focus on the student's ability to correctly multiply the numerator and the denominator to find each equivalent fraction. After students have done correct calculations, students must show evidence that the fractions are equivalent or not equivalent. They can create 2 fraction strips or circles, demonstrating the relationship between the 2 fractions.
 They will explain the relationship between the 2 fractions (verbally or in written form) and tell what part of the whole they both represent. *Remind students that it is easier to start with the smaller fraction.
 1/2 = 4/8 Yes, equivalent.
 3/4 = 1/4 No.
 1/5 = 4/20 Yes.
 3/6 = 1/2 Yes.
 2/4 = 6/6 No.

Learning Objectives: What should students know and be able to do as a result of this lesson?
 Students will create an equivalent fraction when given a benchmark fraction.
 Students will be able to multiply the numerator and denominator of a fraction by 2, 3, or 4 to find equivalent fractions.
 Students will be able to explain why the created equivalent fractions are equivalent using visual examples or written/verbal explanations.

Guiding Questions: What are the guiding questions for this lesson?
 What are equivalent fractions? (Fractions that have the same relationship to one.)
 Why do both the numerator and the denominator need to be multiplied by the same number to create an equivalent fraction? (The numerator and the denominator must both continue to represent an equivalent part of the whole when changing to an equivalent fraction.)

Prior Knowledge: What prior knowledge should students have for this lesson?
 Students should be able to multiply numbers 110.
 Students should be able to determine if two benchmark fractions are equivalent by creating fraction bar visual examples of them.

Teaching Phase: How will the teacher present the concept or skill to students?
*Prior to instruction, have small paper plates (spinner circles), square card stock, fraction strips, whiteboards and whiteboard markers ready. The overhead projector is not necessary for this activity but is recommended.
 Hook: "Today we are going to make the next part of our game board using fractions. Part of our game requires us to know how to create equivalent fractions out of any fraction that we are given. We are going to start learning how to do that with the numbers 2, 3 and 4."
 "We are going to use our paper plates to make some fractions, similar to what we did yesterday (in Fraction Land lesson) with our fraction strips."
 "Now our classroom assistant is going to pass out scissors and "spinner circles," white boards, and markers. Please hold your scissors and circle up so that I can see that you have them." (Each student will receive one precut circle/paper plate and scissors. Be sure to have extras if students make mistakes.)
 "Now that we all have our spinner circles, please fold the circle once. When you do this, what fraction does one section of our spinner circle represent? (Have the students write down the fraction representing one section of the circle on their white boards. The fraction should be 1/2."
 "What part of the whole does the fraction, 1/2, represent (random student)? (Response can be: half, one of the two parts.) Good."
 "We are going to take our benchmark fraction that we see all the time, 1/2, and we are going to create an equivalent fraction using multiplication. We are going to use the number 2."
 "When we make equivalent fractions using multiplication, we have to remember that anything we do to the top of the fraction, or the numerator, we also have to do to the bottom of the fraction, or the denominator." (Stress this "if we do something to the top, we have to do it to the bottom also")
 "Using the number 2, I'm going to multiply the numerator by two. 2 x 1 = 2. I'm going to multiply the denominator by 2. 2 x 2 = 4. So the equivalent fraction that we created is 2/4. Does anyone remember from yesterday how we were able to find 2/4 using our fraction strips? Good." (Allow a moment for questions. At this point, you may go into explaining why you can multiply by the fraction 2/2 and how it does not change what the benchmark fraction represents, but that is it's own lesson and it is better to leave that for teaching the identity property unless asked by a student.)
 "Now you might be skeptical about whether or not 1/2 really is equivalent to 2/4, even though we proved that yesterday. Let's go to our next step to help us out."
 "Take your circle and fold it along your 1/2 fold again. Now, fold the top point of your half circle down to the bottom point of your half circle."
 "How many sections have we created? (4) Each section should represent what fraction of the circle? (1/4)
 "Two of the sections or 2/4 is the fraction we found to be equivalent with 1/2. Do 1/2 and 2/4 represent the same amount of the circle?" (Yes.)
 "We have found our first equivalent fraction using multiplication. Let's find another. Look at 2/4."
 "Earlier we said that 1/2 represent half or one of the two parts of the whole."
 "If that is true, what does 2/4 represent? We just found out that it is equivalent to 1/2, so what should 2/4 represent? (Half or two of the 4 parts.) Very good."
 "Let's take that 2/4 and multiply the numerator and denominator by 2 again."
 "Each time you use this method to find equivalent fractions, it should look just like this." (Stress to students that you will be looking for this setup on their assessments.)
 "We are going to move into some more examples using numbers other than 2. Do you think we will get equivalent fractions if we use a number other than 2, like 3 or 4?" (Yes, because we are still multiplying the numerator and the denominator by the same number. Use this moment for more formative assessment and to take any questions about the lesson so far.)
*"Please write your name on the back of your spinner circle and cardstock square. When you are done with today's lesson, Ill give you the final pieces to make your spinner.

Guided Practice: What activities or exercises will the students complete with teacher guidance?
Students will use their whiteboards and markers for the next part of this lesson.
 "For the next part of the lesson, I'm going to take suggestions for which number to use."
 "Now would be a good time to get out your multiplication charts if you need them. This is a lesson on equivalent fractions, not multiplying, so please use them if needed."
 "We don't want to make our fractions too complex so you can choose from 2, 3, or 4."
 "What number are we using first?" (2)
 "Ok, if I give you the fraction 3/4, give me an equivalent fraction using the number 2."
 "We created the fraction 6/8 using our multiplication method."
 "Who can tell me what 6/8 represents?" (6/8 shows 6 of the 8 parts which is equivalent to 3/4.) "Great."
 "Now take a 2 fraction circles from your table. Show me one that has 3/4 and one that has 6/8. If you need help folding, raise your hand."
 (When students are done,) "Each of you should now have to fraction circles that show 2 different fractions that represent the same part of the whole."
 "Does anyone have a question about what we just did?"
 "Let's keep the same fraction, 3/4. Let's try another factor to multiply with, 3 this time."
 "We have 3 or 4 left." (random student) "Ok, 3."
 (Random Student), "When you multiply the numerator by 3, what product do you get?" (9) "Very good."
 (Random Student), "What was the product when you multiplied 4 x 3?"(12) "Great."
 "The fraction we should end up with is 9/12. 9/12 is equivalent to 3/4."
 This time take 2 fraction strips. Fold one to show 3/4 and another to show 9/12. Remember, when your are working with higher even numbers like 12, try folding the strip in half until you get 12 parts.
 "Let's try one more fraction before I let you all work on your own. We are going to work with the fraction 1/4 and the number 4."
 "Just to recap, first, I am going to multiply my numerator by 4. When I do this, what should I get?" (random student?) (4) "Very good."
 "Next, I am going to multiply my denominator by the same number, 4. When I do this, what should I get?" (random student?) (16) "Good."
 "If new numerator is 4 and my new denominator is 16, then my equivalent fraction should be 4/16."
 "Now make 2 more visual representations of your fractions, 1/4 and 4/16. You can use the circles or the strips, but you must you 2 of either one." (At this point, you can survey or walk around the room and collect more formative assessment data or offer help.)
 Alright, I think that is enough practice. If you still think you need to work with me please raise your hand. (This can be an opportunity to gather Response to Intervention (RTI) data or work in a small group.)

Independent Practice: What activities or exercises will students complete to reinforce the concepts and skills developed in the lesson?
Paper bag fractions:
 For each student prepare one bag with 2 groups of items in them.
 On each back, tape an index card that is broken into 2 columns (3 if there is room on the card).
 Write "results" at the top of each column on the index card. Inside of each back should be 3 groups of items.
 Items can be pencils, colored blocks, dice, straws, or coins.
 Items should clearly represent a fractional amount such as 2 red pencils and 1 blue pencil. The fraction can be 1/2. Remind students that for right now, the smaller number should be the numerator.
Directions are as follows:
 "Each student has a bag." (You can play up the suspense of what's in the bag if you choose.) "At this time, please remove the contents of your bag put them on your desk. Take a look at them and make sure you know what they are and how they are different." (Allow a minute or two for students to examine the items.)
 "Please put all the similar items together. Pencils with pencils, bears with bears, etc."
 (Use a students items as an example.) "(Random Student) has 3 pencils. 2 are blue and 1 is red. What fraction can he make with those items? (1/3 or 2/3) That's right, 2 of the 3 pencils are red."
 "Your job is to write the fraction you found in the bag and then 2 equivalent fractions. You get to choose which number you multiply by. Use your white board to do your calculations. Record your equivalent fractions on the card attached in the format that I showed at the beginning of this lesson."
 "(On the board,) So if my fraction is 2/3, I'll write 2/3 and then I'll choose the number 2. I'll multiply the numerator and the denominator by 2 and I get the equivalent fraction 4/6. I write my name and my whole answer on the card attached to the bag."
 "When another student is done with their bag, raise your hand and you can switch bags with them."
"When all the columns on a card are full, bring me the bag and Ill give you the other pieces to build you board game spinner."

Closure: How will the teacher assist students in organizing the knowledge gained in the lesson?
 Exit Slips: The exit slip is either a premade document or it can be scrap paper or flash card, used as a formative assessment and to transition into the next subject or activity.
 Possible questions for your exit slips:
 Why are 2/4 and 4/10 NOT equivalent fractions? (They do not have the same relationship to one.)
 Explain, in your own words, why multiplying the numerator and denominator of a fraction create an equivalent fraction.
 In 2 or 3 sentences, tell me one thing you learned, or did not understand about today's lesson.
 Were the items that you found in your bag what you expected? What items would you have liked to see? (I like to give at least one question that any student would want to respond to but make sure it give you information that you can use in the future.)
