★★★★★

5.0 (1 rating)

In the 'Great Fraction Pizza Party' project, second-grade students explore fractions by creating pizzas, learning to model and identify halves, quarters, eighths, and tenths using real-life scenarios. Students engage in various activities such as ingredient card games, pizza-sharing calculations, and collaborative pizza-making, gaining practical skills in comparing, ordering, adding, and subtracting fractions. Through interactive challenges like escape rooms and treasure hunts, students not only deepen their understanding of fractions but also enhance their problem-solving and teamwork abilities, culminating in a comprehensive portfolio showcasing their mastery of fraction concepts.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we create our own pizzas while exploring the different ways fractions like halves, quarters, eighths, and tenths help us in understanding math concepts?

Essential Questions

Supporting questions that break down major concepts.

What are fractions and why are they useful?
How can we identify and model halves, quarters, eighths, and tenths using real-life examples, like pizzas?
What strategies can we use to compare and order unit fractions?
How do we calculate unit fractions of a given number and apply this knowledge in everyday situations?
In what ways can we add and subtract fractions with the same denominator, and why is this important?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:

Students will be able to identify and model fractions of halves, quarters, eighths, and tenths using real-life examples such as pizza.
Students will learn strategies to compare and order unit fractions effectively.
Students will calculate unit fractions of a given number and apply this knowledge to solve real-life problems.
Students will demonstrate the ability to add and subtract fractions with the same denominator.

Common Core Standards

2.G.A.3

Primary

Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.Reason: The project involves partitioning pizzas to model fractions, which aligns with understanding how to partition shapes into equal shares.

2.NF.A.3

Primary

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.Reason: Comparing and ordering fractions is a key component of the project, directly aligning with explaining equivalence and comparison of fractions.

2.OA.A.1

Secondary

Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.Reason: The project involves adding and subtracting fractions with the same denominator, which is similar to solving problems using addition and subtraction.

2.NF.B.6

Primary

Solve problems involving basic addition and subtraction of fractions with the same denominator.Reason: This standard directly supports the project's goal of teaching students to add and subtract fractions with the same denominator.

Entry Events

Events that will be used to introduce the project to students

The Mystery Pizza Chef Challenge

Students walk into the classroom to find a video message from "The Mystery Pizza Chef" challenging them to create perfect fractions of pizzas to uncover a special ingredient list that must be used for the school's Great Fraction Pizza Party. This not only sparks curiosity but connects directly with their project goal of understanding fractions.

Math-Fraction Escape Room

Transform the classroom into an escape room where students solve fraction puzzles to 'unlock' pizza ingredients. This adventurous setup challenges their conventional perception of math and encourages teamwork and problem-solving.

Fraction Treasure Hunt

Students embark on a school-wide treasure hunt to find and assemble pizza ingredients, using maps and clues based purely on fractions, leading to a grand pizza-making event. This event directly links fractions with adventure and discovery, appealing to their sense of exploration.

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.

Activity 1

Fraction Comparison: The Topping Challenge

Students will compare and order fractions by determining how much of each ingredient they need for their pizzas. Through a fun 'ingredient card' game, they will position ingredients based on fractional needs, learning to compare different fractions effectively.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Provide each student with a set of ingredient cards showing different fractions (e.g., 1/2 cheese, 1/4 pepperoni).

2. Students will arrange these cards from smallest to largest fractions.

3. Discuss as a class why certain fractions are larger or smaller and relate them to pizza ingredients needed.

Final Product

What students will submit as the final product of the activityCompleted fraction order chart with ingredient cards placed in sequence from smallest to largest fractions.

Alignment

How this activity aligns with the learning objectives & standardsSupports standard 2.NF.A.3 by explaining the equivalence and comparison of fractions.

Activity 2

Slice & Dice: Fraction Calculation Fiesta

Learners will calculate unit fractions and apply this calculation to real-life scenarios. They will be tasked with determining how much pizza each person gets when divided equally among different numbers of people.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Divide students into small groups and give each group a pizza image divided into 8 or 10 slices.

2. Present scenarios where these pizzas have to be shared among a certain number of people.

3. Guide students to calculate how much (what fraction of pizza) each person would receive.

Final Product

What students will submit as the final product of the activityWritten explanations of how each group solved their fraction problems and a display of the divided pizza images.

Alignment

How this activity aligns with the learning objectives & standardsAddresses the learning goal of calculating unit fractions and aligns with standards related to modeling fractions (2.G.A.3).

Activity 3

Fraction Addition & Subtraction: Numbers on the Dough

This activity emphasizes the addition and subtraction of fractions through an interactive pizza-making session where students must collaborate to complete 'pizza orders' that require combining or dividing fractions.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Introduce scenarios where students need to add or subtract certain fractions of ingredients (e.g., needing an extra 1/4 mushroom).

2. Using pizza models or drawings, students will perform additions and subtractions.

3. Students write down their fraction equations and solutions for each scenario.

Final Product

What students will submit as the final product of the activityA completed set of fraction equations showing the addition and subtraction needed to fulfill pizza orders.

Alignment

How this activity aligns with the learning objectives & standardsAligns with 2.NF.B.6 and 2.OA.A.1 by teaching students to add and subtract fractions, and solve problems using these operations.

Activity 4

Fraction Fundamentals: Pizza Jam Session

In this activity, students will dive into the very basics of understanding fractions by using pizzas. They will learn to partition circles into halves, quarters, eighths, and tenths by constructing pizza models out of colored paper. This will scaffold their understanding of equal parts and how different fractions represent different amounts of the same whole.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Introduce the concept of fractions using a real pizza, showing how it can be divided into equal parts.

2. Provide students with paper circles and colored pencils.

3. Guide students to carefully partition the circles into halves, quarters, eighths, and tenths using the colored pencils.

4. Have students label each partition with the correct fraction and color code the similar fractions.

Final Product

What students will submit as the final product of the activityA visually engaging portfolio with labeled pizza models showing different fractions.

Alignment

How this activity aligns with the learning objectives & standardsAligns with 2.G.A.3 by helping students partition shapes into equal shares and describe the shares.
