Exploring Number Patterns
– What are number patterns?
– A sequence of numbers following a rule
– Types of patterns in sequences
– Look for arithmetic, geometric, or repeating patterns
– Patterns in math and life
– Helps with predictions and problem-solving
– Recognizing patterns practice
– We’ll find patterns in different sequences together
|
Begin the lesson by explaining what number patterns are, emphasizing that they are sequences of numbers that follow a specific rule. Introduce different types of patterns such as arithmetic (adding or subtracting a constant value) and geometric (multiplying or dividing by a constant value). Discuss the importance of patterns in math for predicting the next numbers in a sequence and in life for establishing routines and making sense of the world. Engage students with practice exercises where they identify and extend various number patterns. Encourage them to explain the rule they see in each pattern and how they used it to determine the next numbers.
Exploring Number Patterns
– What is a number pattern?
– A sequence following a specific rule
– Examples: Count by 2s, 5s, 10s
– 2, 4, 6, 8, … or 5, 10, 15, 20, …
– Let’s find patterns together!
– We’ll identify patterns as a class
– Practice with different sequences

Introduce the concept of number patterns to the students by defining what a number pattern is and explaining that it follows a specific rule. Provide simple examples that they are familiar with, such as counting by 2s, 5s, and 10s. Engage the class by working together to identify patterns in different sequences. Encourage participation and guide them through the process of discovering the rule behind each pattern. For practice, present various sequences and ask students to determine the rule and continue the pattern. This activity will help solidify their understanding of number patterns and prepare them for more complex sequences in future lessons.
Exploring Types of Number Patterns
– Arithmetic patterns: add or subtract
– Add or subtract the same value each time, e.g., 2, 4, 6, 8 (+2)
– Geometric patterns: multiply or divide
– Multiply or divide by a consistent number, e.g., 3, 9, 27, 81 (x3)
– Other patterns: various changes
– Look for sequences that repeat, grow, or shrink, e.g., 1, 1, 2, 3, 5, 8…
– Recognizing and using patterns
|
This slide introduces students to the concept of number patterns, a fundamental part of mathematics. Arithmetic patterns involve a constant addition or subtraction between consecutive numbers. Geometric patterns involve multiplication or division by a fixed number. Other patterns may include repeating sequences, or those that grow or shrink in a non-uniform manner. Encourage students to practice by identifying the rule in different patterns and creating their own sequences. Understanding these patterns lays the groundwork for algebraic thinking and problem-solving skills.
Finding the Rule in Number Patterns
– Understanding pattern rules
– A rule tells us how numbers change in a pattern
– Identifying arithmetic operations
– Check if numbers increase by addition, decrease by subtraction, multiply, or divide
– Practice with pattern examples
– Example: 2, 4, 6, 8; what’s happening to the numbers?
– Discuss pattern findings
– Share your rule discoveries with the class
|
This slide is aimed at helping students understand how to determine the rule of a number pattern. Start by explaining that a rule is a consistent way numbers change in a pattern. It could be an addition, subtraction, multiplication, or division. Use simple examples to illustrate each operation within a pattern. For practice, provide a series of patterns and ask students to identify the rule. Encourage them to explain their reasoning and how they arrived at the rule. This activity will enhance their analytical skills and understanding of sequences. In the next class, students can share their findings, fostering a collaborative learning environment.
Creating Our Own Number Patterns
– Time to get creative with numbers!
– Let’s craft our unique number patterns
– First, think of a rule for your pattern
– A rule could be ‘add 3’ or ‘subtract 2’
– Use your rule to make a pattern
– If your rule is ‘add 3’, your pattern might look like 4, 7, 10, 13

This slide is designed to engage students in an interactive class activity where they apply their understanding of number patterns by creating their own. Start by encouraging creativity and reinforcing the concept of a ‘rule’ that dictates the pattern. Provide guidance on how to establish a simple rule, such as adding or subtracting a consistent number. Once students have decided on their rule, they should apply it to generate a sequence of numbers. For the activity, consider having students work in pairs to create patterns and then share with the class, or write their patterns on the board for a group discussion. This exercise will help solidify their grasp of number patterns and demonstrate their ability to recognize and apply rules to create sequences.
Patterns in Real Life
– Patterns exist all around us
– Nature’s patterns: leaves and snowflakes
– Examples: the veins in a leaf, the unique symmetry of a snowflake
– Music and art are full of patterns
– Rhythms, beats in music, and repeated designs in art
– Daily routines have patterns too
– Morning activities, or the order we get ready for school
|
This slide aims to show students that patterns are not just a mathematical concept but are also present in everyday life. Start by explaining what a pattern is: a repeated or recurring design or sequence. Then, give examples from nature, such as the arrangement of leaves on a stem or the intricate designs of snowflakes. Highlight how patterns are fundamental in music and art, with beats and rhythms in songs or patterns in paintings and sculptures. Finally, relate it back to the students’ daily lives by discussing the sequence of activities they do every morning or evening, helping them recognize the patterns they follow. Encourage students to observe the world around them for patterns and share their observations in class.
Class Activity: Pattern Detectives
– Become a Pattern Detective!
– Find patterns on your worksheet
– Look for sequences in shapes, colors, or numbers
– Complete the missing numbers
– Use logic to figure out what comes next
– Work in pairs for teamwork
– Share ideas and solve together
|
In this engaging class activity, students will pair up to become ‘Pattern Detectives.’ Each detective pair will receive a worksheet filled with various number patterns. Their task is to identify the type of pattern (e.g., adding, subtracting, alternating) and fill in the missing elements. Encourage students to discuss their strategies with their partners and to check each other’s work for accuracy. Possible activities include: finding patterns with a fixed number addition or subtraction, identifying patterns with multiplication or division, and creating their own patterns for others to solve. This activity promotes collaborative learning and critical thinking as students explore different number patterns.
Review and Share: Number Patterns
– Recap today’s number patterns
– Share your pattern discoveries
– What patterns did you notice in your exercises?
– Discuss any questions
– Are there parts of number patterns you’re curious about?
– Interesting observations?
– Did you find any patterns surprising or particularly cool?

This slide is meant to facilitate a discussion and review of the day’s lesson on number patterns. Encourage students to think about what they’ve learned and articulate their understanding of number patterns. Have them share the patterns they’ve discovered in their classwork, fostering a collaborative learning environment. Open the floor for any questions the students might have, addressing misunderstandings or reinforcing concepts. Also, prompt them to share any interesting observations they’ve made during the lesson to engage their curiosity and interest in the subject. This will help consolidate their learning and ensure they are comfortable with the material covered.
Pattern Detectives: Homework Mission

This slide wraps up the lesson on number patterns and transitions students to their homework assignment. They are tasked with creating their own number pattern, which reinforces their understanding of sequences and the rules that govern them. Encourage creativity and remind them to think about patterns they see in their daily lives for inspiration. The homework also includes writing down the rule of their pattern, which could be an addition or subtraction rule, for example, ‘add 3’ or ‘subtract 2’. Lastly, prepare them to present their pattern in the next class, which will help build their confidence in explaining mathematical concepts. Provide examples of simple patterns to get them started, such as ‘2, 4, 6, 8, …’ with the rule ‘start at 2 and add 2 each time’.
