# Lesson Plan Template

• #### Vocabulary

• Addition Sentence: A mathematical statement that shows two numbers being added together, like 3 + 1 = 4.
• Pattern: A repeated or recurring sequence that follows a specific rule.
• Sequence: An ordered set of numbers or objects.

### Materials and Preparation

• Whiteboard and markers
• Addition Sentences Pattern Worksheet Pack (including guided practice, independent practice, exit tickets, homework, and assessment)
• Small counters or manipulatives for each student (e.g., counting bears, blocks)
• Document camera or projector to display worksheets

### Learning Objectives

• Students will be able to identify numerical patterns in simple addition sentences.
• Students will understand and apply the concept of increasing and decreasing numerical sequences in addition.
• Students will solve for missing numbers in addition sentences based on identified patterns.

### Introduction

Begin the lesson by introducing the concept of patterns in numbers, especially focusing on sequences in addition. Display several simple addition sentences and ask students if they notice anything about the numbers. Example: 5 + 1 = 6, 6 + 1 = 7. Explain that today they will become detectives looking for clues in number patterns to solve addition puzzles.

### Explicit Instruction/Teacher modeling

Explain the concept of increasing and decreasing sequences. Demonstrate with examples on the whiteboard:

• For increasing sequences, each number is one more than the number before it (Example: 2, 3, 4, ...).
• For decreasing sequences, each number is one less than the number before it (Example: 4, 3, 2, ...).

### Guided Practice

Using the Addition Sentences Pattern Worksheet under the document camera, work through several examples together. Highlight how each addition sentence in the sequence adheres to the established pattern, either increasing or decreasing. For instance, show a sequence where the first number in each sentence increases by one, and the second number decreases by one.

### Independent Practice

Students will complete a worksheet where they identify and fill in missing numbers in addition sentences by recognizing the patterns. They will use counters or manipulatives to physically manipulate the numbers, helping to solidify their understanding of the sequence.

## Support

• Provide number lines or visual aids for students who struggle with abstract number concepts.
• Work in small groups or pairs for students needing additional support, allowing peer learning.

## Extension

• Challenge students to find patterns in subtraction sentences.
• Introduce patterns using three numbers in an addition sentence.

### Assessment

Use the Assessment worksheet from the Worksheet Pack, which includes several patterns of addition sentences. Students will identify and complete missing parts of each sequence, demonstrating their understanding of patterns in addition.

### Review and closing

Review the patterns discovered today and discuss any common misconceptions, such as confusing the increase and decrease in sequences. Open the floor for students to ask questions or share observations about patterns in numbers.

### Misconceptions

1. Students may think the sequence always increases. Clarify that patterns can increase or decrease.
2. Students might confuse the position of numbers in an addition sentence, affecting their understanding of the pattern.
