Welcome to Fractions!
– What is a fraction?
– A fraction represents a part of a whole.
– Parts make a whole
– Like pieces of a pie put together to make a full pie.
– Whole numbers as fractions
– 1 can be written as 1/1, 2 as 2/1, and so on.
– Equivalent fractions
– 2/1 is the same as 2 whole pies.

This slide introduces the concept of fractions to third-grade students. Begin by explaining that a fraction represents a part of a whole, using tangible examples like slices of a pie or pizza. Show how multiple parts come together to form a whole item. Then, demonstrate how whole numbers can be expressed as fractions with a denominator of 1, reinforcing the idea that the numerator indicates how many parts of that whole we have. Lastly, explain that fractions like 2/1 are equivalent to whole numbers, in this case, two whole pies, to help them understand the concept of equivalent fractions. Use visual aids like fraction models or pie charts to illustrate these points clearly.
Understanding Fractions
– A fraction shows part of a whole
– Top number is the numerator
– It tells us how many parts we have
– Bottom number is the denominator
– It tells us into how many parts the whole is divided
– Examples: Pizza and watermelon slices
– 1/2 pizza means half; 3/4 watermelon means three out of four parts

Begin by explaining that a fraction represents a part of a whole, like a piece of a pie or a slice of pizza. The numerator, the top number of a fraction, indicates how many parts we’re talking about, while the denominator, the bottom number, shows how many equal parts the whole is divided into. Use visual aids like pictures of a pizza cut into halves or a watermelon cut into quarters to illustrate fractions. Encourage students to think of fractions as parts of their favorite foods or activities to make the concept relatable and easier to grasp. The goal is for students to understand that fractions are another way of representing numbers and quantities.
Whole Numbers as Fractions
– Whole numbers as fractions
– Numerator equals denominator
– Like 2 is the same as 2/2 or 3 as 3/3
– One whole equals one part
– Think of a pizza cut into 1 big slice
– Examples with models
– Use pie charts to show 1 as 1/1, 2 as 2/2

This slide introduces the concept that whole numbers can be represented as fractions. Emphasize that when the numerator (the top number) and the denominator (the bottom number) are the same, the fraction is equivalent to a whole number. For example, 1 can be written as 1/1, 2 as 2/2, and so on. This is because the fraction represents one whole thing, like a pizza that hasn’t been cut or a pie chart with one big piece. Use visual aids like models or pie charts to help students visualize this concept. Encourage them to think of other whole numbers as fractions and draw their own models. This foundational understanding will be crucial as they progress in learning about fractions.
Understanding Equivalent Fractions
– What are equivalent fractions?
– Fractions with the same value
– Examples: 2/2 and 3/3 equal 1
– 2/2 and 3/3 are both equal to 1 whole
– Using models to show equivalence
– Draw circles or bars divided into equal parts
– Equivalent fractions to whole numbers

This slide introduces the concept of equivalent fractions to third-grade students. Begin by explaining that equivalent fractions are different fractions that represent the same value. Use simple examples like 2/2 and 3/3 to show that they both equal one whole. Demonstrate with visual models such as pie charts or bar models, dividing them into equal parts to illustrate how these fractions are equivalent to a whole number. Emphasize that even though the number of parts may differ, if all parts are combined, they make up a whole. Encourage students to think of other examples and use models to represent them. This will help solidify their understanding of equivalent fractions in relation to whole numbers.
Understanding Fractions with Models
– Explore fraction circles and bars
– Visual tools to see fractions clearly
– Count parts to make a whole
– If 4/4 parts are put together, it’s 1 whole
– All parts together make a whole
– Combining all slices of a circle shows a whole
– Equivalent fractions to whole numbers

This slide is aimed at helping third-grade students understand the concept of fractions equivalent to whole numbers using visual models such as fraction circles and bars. Start by showing them how these models represent fractions, with each part of the model representing a fraction of the whole. Then, demonstrate how combining all the parts of the fraction model equals one whole unit. Emphasize that when the number of parts equals the denominator, the value is equivalent to one whole. For example, 4/4 or 8/8 both represent one whole. Encourage students to use these models to visualize and better understand the concept of equivalent fractions and whole numbers.
Let’s Practice Together: Fractions as Whole Numbers
– Observe the given fraction
– Is it equivalent to a whole number?
– A fraction like 3/3 or 4/4 equals 1
– Use models to verify
– Draw circles or bars divided into equal parts
– All parts make a whole? It’s a whole number!
– If all parts are shaded, it equals 1

This slide is an interactive class activity designed to help students understand the concept of fractions equivalent to whole numbers. Start by showing a fraction to the class and ask them to determine if it represents a whole number. Use visual aids like fraction models (circles or bars) to demonstrate the concept. For example, if a model is divided into three parts and all three parts are shaded, it represents the fraction 3/3, which is equivalent to the whole number 1. Encourage students to draw their own models and shade in the parts to visually verify if the given fraction is equivalent to a whole number. This hands-on activity will reinforce their understanding of fractions and whole numbers.
Class Activity: Fraction Fun!
– Try finding fractions with models
– Work together in pairs
– Find fractions equal to whole numbers
– Use fraction circles or bars to see how many parts make a whole
– Share your discoveries with the class

This activity is designed to reinforce the concept of fractions equivalent to whole numbers through hands-on practice. Provide students with fraction models such as circles or bars. Guide them to work in pairs to explore how many equal parts make up a whole, emphasizing that fractions like 1/1, 2/2, 3/3, etc., are all equivalent to one whole. Encourage them to find other examples, such as 4/4 or 8/8. After the activity, ask the pairs to present their findings to the class, fostering a collaborative learning environment. Possible variations for different pairs could include using different models, finding fractions equivalent to numbers other than one, or creating a poster of their findings.
Conclusion & Homework: Exploring Fractions at Home
– Excellent work on whole number fractions!
– Homework: Find and write fractions of home objects
– Look for items you can divide into equal parts
– Remember: Practice leads to improvement
– The more you work with fractions, the better you’ll understand
– Share your findings next class!

Today’s lesson focused on understanding how fractions can represent whole numbers when the numerator and denominator are the same. For homework, students are encouraged to find everyday objects that can be divided into equal parts and write down the fraction that represents the whole object (e.g., a pizza cut into 8 equal slices is 8/8). Remind students that consistent practice is key to mastering fractions. In the next class, ask students to share their examples, which will help reinforce their understanding and allow them to see how fractions are part of their daily lives.
