Engaging Patterns

Lesson Overview

Objective

Students will develop an understanding of nonnumerical patterns with a focus on repeating and growing patterns. By the end of the lesson, students should be able to identify, describe, and create both types of patterns using everyday objects.

Curriculum Area

Mathematics - Patterns and Algebra

Grade Level

4th Grade (Aligned with US Common Core Standards: CCSS.MATH.CONTENT.4.OA.C.5)

Materials Needed

• Colored tiles or blocks (enough for each group of students)
• Pattern cards or images
• Whiteboard and markers
• Chart paper and markers
• Pattern worksheet for individual practice

Lesson Structure

Introduction (5 minutes)

1. Greeting and Warm-Up: Begin with a brief discussion by asking students if they can think of patterns they see in everyday life. Examples might include patterns in clothing, wallpaper, or floor tiles.

2. Objective Sharing: Explain to the students that today they will be exploring two types of patterns: repeating patterns and growing patterns. Write the objectives on the board:

   • Identify and describe repeating patterns.
   • Identify and describe growing patterns.

Direct Instruction (5 minutes)

1. Revisiting Patterns:

   • Define a repeating pattern using simple examples, such as colors or shapes (e.g., red, blue, red, blue).
   • Define a growing pattern and give examples where the elements increase or decrease in a systematic way (e.g., one tile, two tiles, three tiles...).

2. Interactive Examples:

   • Use colored tiles to physically create a short repeating pattern and a growing pattern on the board.
   • Discuss how repeating patterns have a unit that repeats over and over, whereas growing patterns change with each step.

Interactive Activity (10 minutes)

1. Group Work: Divide students into groups of 3-4.

2. Task:

   • Provide each group with colored tiles or blocks.
   • Assign each group to create one repeating pattern and one growing pattern using the materials provided.
   • Instruct students to describe their patterns in words on a piece of chart paper.

3. Class Discussion:

   • Have each group briefly present their patterns to the class, explaining their decisions.
   • As each group presents, encourage students to identify the 'rule' or logic behind each pattern.

Reflection and Wrap-Up (5 minutes)

1. Class Reflection:

   • Ask students to reflect on the differences between repeating and growing patterns. Write key points on the board.
   • Facilitate a short discussion on the importance of patterns in the real world and where they might notice them daily.

2. Worksheet: Distribute a worksheet with a mix of patterns and instruct students to complete a section on identifying and extending both repeating and growing patterns.

3. Closing: Praise students for their creativity and collaboration. Highlight the importance of recognizing patterns as a skill that is used in various aspects of life.

Assessment

• Informal Observation: During group activities, observe students’ understanding and participation.
• Worksheet: Evaluate the completed worksheets to assess individual comprehension of pattern identification and application.

Extensions

• For students who have mastered the concept, introduce patterns with more complexity, such as alternating two growing patterns or introducing a surprise element in a growing pattern.
• Encourage artistic students to find or create patterns in art or nature.

This lesson includes interactive and creative elements designed to engage fourth-grade students in understanding and applying nonnumerical patterns, thereby satisfying both educational standards and inspiring enthusiasm for mathematics.
