Welcome to Equivalent Fractions! – Understanding basic fractions – Fractions represent parts of a whole – Exploring equivalent fractions – Fractions with different numbers but the same value – Importance of equivalent fractions – Useful for comparing and simplifying fractions – Finding missing numbers in fractions – Use multiplication or division to find missing values | This slide introduces the concept of equivalent fractions to fourth-grade students. Begin by explaining what fractions are and how they represent parts of a whole, ensuring students understand the terms numerator and denominator. Then, move on to equivalent fractions, showing how different fractions can express the same value. Emphasize the importance of equivalent fractions in making comparisons and simplifying calculations. Finally, demonstrate how to find missing numerators or denominators by using multiplication or division, providing examples and encouraging students to practice this skill. Prepare to have interactive activities where students can practice finding equivalent fractions with different numerators and denominators.

Understanding Fractions – A fraction shows part of a whole – Like a slice of pizza is a part of a whole pizza – Top number is the numerator – Bottom number is the denominator – Example: 1/2 of a pizza – 1/2 means 1 out of 2 equal slices | Begin the lesson by explaining that a fraction represents a part of a whole, similar to how a slice of pizza is just a part of the entire pizza. The numerator, which is the top number of the fraction, indicates how many parts we have. The denominator, the bottom number, tells us into how many equal parts the whole is divided. Use the example of a pizza cut into two equal slices where 1/2 means one slice of the two available. This visual can help students grasp the concept of fractions as parts of a whole. Encourage students to think of other examples of fractions they encounter in everyday life.

Exploring Equivalent Fractions – Understanding equivalent fractions – Fractions with the same value – They may look different but are equal in value – Example: 1/2 equals 2/4 and 3/6 – 1/2 is the same as 2/4 or 3/6 because they divide into equal parts – Finding missing numbers in fractions – Use multiplication or division to find missing numerators or denominators | This slide introduces the concept of equivalent fractions, which are fractions that represent the same part of a whole despite having different numerators and denominators. Use visual aids like pie charts or fraction bars to show that 1/2, 2/4, and 3/6 all represent the same portion of a whole. Explain that by multiplying or dividing both the numerator and denominator by the same number, we can find equivalent fractions or the missing part of a fraction. Encourage students to practice with different fractions to become comfortable with the concept. Provide several examples and exercises where students can apply multiplication or division to find missing numerators or denominators in equivalent fractions.

Finding the Missing Numerator – Use multiplication to find numerator – Multiply the known numerator by the same number you multiply the denominator to get the equivalent fraction. – Divide to check the equivalent ratio – Dividing the denominator of the equivalent fraction by the original denominator gives the multiplier for the numerator. – Example: 1/2 equals ?/4 – If 1/2 is equivalent to ?/4, what number times 1 gives us a numerator for 4? – Solve: Missing numerator is 2 – Since 2 times 1 equals 2, and 2 times 2 equals 4, the missing numerator is 2. | This slide is aimed at teaching students how to find a missing numerator in equivalent fractions. Start by explaining that the ratio of the numerator to the denominator must remain the same in equivalent fractions. Show the multiplication method by using an example where the denominator is multiplied by a number to find the equivalent fraction, and then apply the same multiplier to the numerator. Also, demonstrate the division method as a way to check their work. Use the example provided to illustrate the concept, and then solve it step by step. Encourage students to practice with different fractions and to verify their answers by ensuring the two fractions are equivalent.

Finding the Missing Denominator – Understand the numerator’s role – Multiply to find equivalence – Find what number multiplies the numerator to get the equivalent numerator – Example: 3/? equals 6/8 – 3 multiplied by what equals 6? The answer is 2 – Solve for the missing denominator – If 3 x 2 = 6, then ? x 2 = 8, so the missing denominator is 4 | This slide is aimed at teaching students how to find a missing denominator in equivalent fractions. Start by explaining that the numerator indicates how many parts of a whole we have. To find a missing denominator, determine what number you can multiply the known numerator by to get the equivalent numerator. Use the example 3/? = 6/8 to illustrate this: since 3 times 2 equals 6, the missing denominator must be multiplied by 2 to get 8. Therefore, the missing denominator is 4. Encourage students to practice with different fractions and to check their work by ensuring the cross-products are equal.

Let’s Practice Together: Equivalent Fractions – Find the missing numerator: 2/3 = ?/9 – To find ?, multiply 2 by the number that makes 3 into 9. – Find the missing denominator: 4/? = 8/12 – To find ?, divide 12 by the number that turns 4 into 8. | This slide is an interactive class activity designed to help students practice finding missing numerators and denominators in equivalent fractions. For the first problem, guide the students to understand that they need to find the factor that turns 3 into 9, which is 3, and then multiply the numerator (2) by this factor. For the second problem, they need to find the factor that turns 4 into 8, which is 2, and then divide the denominator (12) by this factor to find the missing number. Encourage students to work through these problems in pairs or small groups and then share their solutions with the class. Provide additional examples if time allows, and ensure to reinforce the concept that equivalent fractions are different fractions that represent the same value.

Class Activity: Fraction Scavenger Hunt – Pair up and explore the classroom – Find objects and create equivalent fractions – For example, if you find 4 blue pens out of 16, what’s an equivalent fraction? – Record your findings – Share with the class | This interactive activity is designed to help students understand equivalent fractions in a fun and engaging way. Have the students work in pairs to encourage teamwork. They should look for objects around the classroom that can be divided into parts, such as a set of markers or a group of books. Once they find an object, they should create equivalent fractions representing parts of the object. For instance, if they find 4 blue pens out of 16 pens, they can create the fraction 4/16 and simplify it to 1/4. After they have recorded their findings, each pair will share their fractions with the class, explaining how they found the objects and determined the equivalent fractions. This will help reinforce their understanding of the concept and allow them to see practical applications of equivalent fractions. Provide guidance and ensure each pair understands the task. Possible variations for different pairs could include finding different colored objects, different shapes, or items in different quantities to ensure a variety of examples.

Wrapping Up: Equivalent Fractions – Review of equivalent fractions – How to find missing numbers Use multiplication or division to find the missing numerator or denominator. – Homework: Practice worksheet Complete the worksheet to find missing values in fractions. – Share what you’ve learned Be ready to discuss the worksheet in the next class. | As we conclude today’s lesson on equivalent fractions, remind students of the key concept: fractions are equivalent if they have the same value when simplified. Reinforce the method of finding missing numerators or denominators by using multiplication or division. For homework, assign a worksheet that provides practice on this concept, ensuring students understand how to apply what they’ve learned. Encourage them to be prepared to share their answers and methods during the next class, fostering a collaborative learning environment. This will help solidify their understanding and give them confidence in working with equivalent fractions.
