Theme 2 : Arithmetic Work-Text

Introduction

INTRODUCTION TO NEW MATERIAL: Explain subtracting fractions using visual aids (e.g., fraction circles). Demonstrate how to convert improper fractions to mixed numbers with examples. Introduce line graphs using a simple data set (e.g., daily temperatures). Anticipate the misconception that students may think you can only subtract whole numbers.

Lesson 58-83| Pgs: 103-150| Subtracting Fractions With Common Denominators. Building A Line Graph. Mixed Numbers. Area. Prime & Composite Numbers. Solid Shapes. 

How do we represent fractions in writing?

What are the rules in constructing a line graph?

STANDARDS ALIGNED: MA.5.F.1.1: Add and subtract fractions with common denominators. MA.5.F.1.2: Understand mixed numbers and improper fractions. MA.5.DP.1.1: Represent and interpret data using line graphs. MA.5.NSO.1.1: Identify prime and composite numbers. MA.5.G.1.1: Understand the properties of solid shapes and their area.

Task

LEARNING OBJECTIVE: Students will be able to subtract fractions with common denominators, identify mixed numbers, and create a line graph based on given data.

Process

KEY POINTS: Subtracting Fractions: Understand how to subtract fractions with the same denominator. Mixed Numbers: Recognize and convert improper fractions to mixed numbers. Line Graphs: Learn how to plot points on a line graph and interpret data. Prime and Composite Numbers: Identify the difference between prime and composite numbers within the context of area. Solid Shapes: Understand the properties of solid shapes and how they relate to area.

OPENING:

  • Begin with a question: "If I have 3/43/4 of a pizza and I eat 1/41/4, how much do I have left?"
  • Engage students with a hands-on activity: use fraction strips to visualize the subtraction of fractions.

INTRODUCTION TO NEW MATERIAL:

  • Subtracting Fractions: Demonstrate using fraction strips or visuals to show how to subtract fractions with like denominators.
  • Line Graphs: Introduce line graphs through examples. Show how to plot points based on data.
  • Mixed Numbers: Explain mixed numbers with visual aids, like pie charts.
  • Area: Use grid paper to help students visualize and calculate the area of different rectangles.
  • Prime vs. Composite Numbers: Use a number chart and highlight prime numbers.

GUIDED PRACTICE:

  • Students will work on example problems on subtracting fractions with guidance.
  • Practice building a line graph using provided data as a class.
  • Solve problems calculating the area of various rectangles.
  • Identify prime and composite numbers from a list with teacher support.
  • Monitor student understanding by walking around and checking their work.

INDEPENDENT PRACTICE:

  • Assign a worksheet with problems on subtracting fractions, constructing a line graph, calculating areas, and identifying prime/composite numbers.
  • Set behavioral expectations: students should work quietly, raise hands for help, and check their answers with a partner once finished.
Evaluation

ASSESSMENTS:

Students will complete a worksheet that includes problems on subtracting fractions, constructing a line graph based on given data, identifying mixed numbers, calculating the area of rectangles, and classifying numbers as prime or composite. Student will also complete a 10 question quiz. Using a rubric:

categories and criteria for my rubric will be:

Excellent

Good

Fair

Poor

Conclusion

CLOSING:

  • Recap the day’s learning by asking students to share one thing they learned about fractions, area, or prime numbers.
  • Conduct a quick quiz with a few questions to reinforce the concepts covered.

EXTENSION ACTIVITY:

  • For students who finish early, provide additional challenges, such as creating their own line graph from a set of data they generate (like favorite fruits).

HOMEWORK:

  • Assign practice problems on subtracting fractions and calculating area.
  • Include a short reading assignment on prime and composite numbers with questions to answer.
