Grade Level

4th Grade

Duration

55 minutes

Class Size

16 students

Common Core State Standards

CCSS.MATH.CONTENT.4.OA.C.5

Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself.

CCSS.MATH.PRACTICE.MP1

Make sense of problems and persevere in solving them.

CCSS.MATH.PRACTICE.MP2

Reason abstractly and quantitatively.

Learning Objectives

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

Identify and describe number patterns using addition, subtraction, and multiplication.
Generate number patterns based on given rules.
Articulate the rule represented in a given number pattern.
Explore and extend number patterns beyond the examples given.
Demonstrate problem-solving and mathematical reasoning skills aligned with standards.

Materials Needed

Whiteboard and markers
Pattern worksheets (with spaces to continue and describe patterns)
Number cards (0-50) for hands-on activity
Colored pencils or markers
Student math journals or notebooks
Timer or stopwatch

Lesson Outline

1. Hook/Introduction (7 minutes)

Begin with a quick brain teaser: Write this sequence on the board — 2, 4, 6, 8, __, __.
Ask students, “What do you notice about the numbers? What would come next and why?”
Guide students toward identifying the pattern rule (adding 2 each time).
Highlight how patterns help us “predict what comes next” in math and the world around us.

Tip for the teacher: Encourage all students to share, fostering a supportive environment for their first ideas.

2. Direct Instruction (10 minutes)

Explain what number patterns are and how they follow specific rules.
Show examples on the whiteboard:
- Increasing pattern (add 3): 3, 6, 9, 12...
- Decreasing pattern (subtract 2): 20, 18, 16, 14...
- Multiplying pattern: 1, 2, 4, 8, 16... (doubling each time)
Model identifying the pattern rule from a sequence of numbers.
Write a pattern and ask the class together what rule it follows.

Visual Aid: Use colored markers to highlight the "rule difference" (e.g., +3, -2).

3. Guided Practice (15 minutes)

Distribute number cards to students, 2-3 per student.
In pairs, ask students to create their own number pattern using their cards and write down the numbers in the sequence on their worksheet. They should also write the rule they used (e.g., add 4 or multiply by 2).
After 5 minutes, pairs swap their pattern with another pair. Each pair figures out the rule of the new pattern and writes it down.

Teacher Circulates: Provide help and ask guiding questions (e.g., “How can you check if your rule works for the whole pattern?”).

4. Independent Practice (15 minutes)

Instruct students to choose or create one pattern from a list on the worksheet (including addition, subtraction, or multiplication patterns).
They will extend the pattern by writing 5 more numbers and then write a short explanation describing the rule in their math notebooks.
Encourage colorful illustrations or symbols to represent the pattern in a creative way.

Tip for the teacher: Use this time to review individual students’ understanding and provide immediate feedback.

5. Assessment and Closure (8 minutes)

Conduct a quick “Pattern Pop Quiz”: On the board, display 3 short number patterns. Students write down the rule for each one on a slip of paper.
Randomly select volunteers to explain their reasoning out loud to the class.
Summarize the importance of patterns and how understanding the rule helps us predict and solve problems.

Differentiation Strategies

For students who need extra support: Use simpler patterns (add 1 or subtract 1) and work in small groups with teacher assistance.
For advanced students: Challenge them to create patterns involving two-step rules (e.g., add 2 then subtract 1, repeat).

Reflection for the Teacher

Which students were able to identify and articulate patterns successfully?
Did students engage with both creating and analyzing patterns?
Were the visual and hands-on activities effective for maintaining attention?
Plan to record student progress and adjust next lessons based on who needs more practice with operations or pattern rules.

This lesson plan focuses on experiential learning and student conversation to build solid pattern recognition skills foundational for later algebraic thinking. Your enthusiasm and support will help build your students’ confidence in math!
