Standard: 4.NF.3.c

Understand a fraction a/b with a > 1 as a sum of fractions 1/b. Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction. (CDE, n.d.)

How can we use fractions to represent parts of a whole in different ways?

Folding Paper to Represent Fractions

Teacher demonstrates how folding paper can create more pieces

Now it's your turn! Let's prove that fractions do exist! Fold your paper strips to create different fractions. Make sure you have at least 3 by the end of the 10 minutes.

In your journal, write the different ways you can represent a fraction like 3/4 using the strips.

Finally, let's turn-and-talk to someone in a different row than you. Share what you learned and any struggles you had.

Teacher Example: Word Problems

We will apply what we learned from activity #1 and solve some real-life word problems with fractions.

Example: Mr. E ate 5/9 of a pizza for lunch, and then he ate 2/9 more for dinner. How much pizza did he eat in total?

We should use our fraction strips to solve this. First, we put 5/9 out using five 1/9 strips. Then, we add two more 2/9 strips to represent the additional 2/9 he had for dinner.

Finally, let's count the total number of 1/9 strips to find the answer. In this case, it's 7/9.

Creating Word Problems

maganaedgar1 — 2024-07-25 21:42:24 UTC

Think of a real-life situation where you might need to add fractions. Create a two-step word problem involving fractions with the same denominator (ex: 1/4, 3/4). Be creative and be ready to share with at least 2 people!

Next, show your problem in different ways. You can use fraction strips, drawings, number lines, or anything else.

Finally, in 2-3 sentences, describe the methods you used to solve the problem and share how they helped you understand the concept.

Fraction Project

Let's explore how fractions are used in everyday life! You will choose a topic, gather information, analyze it using fractions, and present it to the class next week.

Example topics: cooking, video games, sports, shopping, school exams, etc.

Collect information related to your topic. If you choose cooking, you will likely look at the fractions of the ingredients in a recipe.

Analyze and use different methods to explore your fractions (like we did in class) such as drawing pictures, using fraction strips, or creating number lines. You got this!

Finally, you will create your presentation. You can make a poster, a drawing, a short video, or a slideshow.

You will be grading your classmates' efforts and presentation skills. Each student must grade 3 of their classmates and turn in the rubric to me. Please make sure you leave comments as you go!

Reminders: The presentation must include information you collected, how you analyzed it using fractions, and interesting/cool facts.
