Recognizing and Creating Patterns


Recognizing and creating patterns is an essential skill in math. It helps us understand the world around us and it can be especially fun and engaging, especially for young learners in Grade 2. In this exploration, we'll take a deeper look at how students can recognize and create patterns using simple terms and examples.

Understanding the pattern

A pattern is a repeated design or recurring sequence. In mathematics, patterns are often numbers or shapes that follow a specific rule or order.

Simple pattern with shapes

Let's start with a simple example. Look at the sequence of shapes below:

This sequence follows the simple pattern of square, circle, square, circle. If we want to continue this pattern, the next figure will be a square.

Simple numerical patterns

Recognizing numerical patterns can be just as easy. Consider the following series of numbers:

2, 4, 6, 8, 10, ...

In this sequence, we add 2 to each previous number to reach the next number. Here is the pattern rule: add 2 each time. If we continue this pattern, the next number will be 12.

Creating patterns

Pattern making is about continuing the pattern or starting new sequences based on a rule. The ability to make patterns reflects an understanding of repetition and sequence in mathematics.

Pattern with shapes

Create a pattern using the shapes below:

If you start with a circle and then make a square, then continue doing this with alternating shapes. You will have a pattern that looks like this:

Patterns with numbers

Create a pattern using the numbers, such as starting with 5 and adding 3 each time:

5, 8, 11, 14, ...

In this numerical sequence, the next number is formed every time 3 is added. Continuing this pattern, the next number will be 17.

Pattern recognition strategies

Recognizing patterns can be easier with some strategies. Let's look at some techniques:

Focus on repetition

Many patterns rely on repetition. Identifying the repeated element can often help you see the entire pattern.

Consider this visual sequence:

The repeating unit here is two orange circles followed by a purple square.

Use the count

Another helpful strategy is to count the number of units before repeating. This works especially well with shapes.

Look at this numerical sequence:

10, 15, 20, 25, ...

Each number is 5 more than the previous number.

Applications in real life

Patterns help children understand the rules that govern the natural world around them.

For example, consider the pattern for the days of the week:

Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday...

This sequence is repeated every 7 days, which mark the weeks. Recognizing this pattern helps children plan daily routines or events.

Challenges and activities

Here are some fun exercises you can try with young learners to enhance pattern recognition skills:

Pattern continuation

Expand the pattern by adding more elements:

Repeat for three more cycles. You can also ask students what would happen next if this continued.

Pattern creation

Ask students to create their own patterns using blocks of different colours and shapes.

Fill in the blanks

Fill in the missing numbers or shapes in the pattern:

3, 6, __, 12, ...

Help them recognize the rule and suggest that the missing number is 9 (because each number increases by 3).

Expanding pattern understanding

As learners understand basic pattern concepts, introduce more complex ideas, such as two rules in the same pattern.

Alternating pattern rules

Consider a sequence where the rules alternate:

Start with 1: add 2, then multiply by 2. 
1, 3, 6, 8, 16, 18, 36, etc.

Here, notice the alternative operations applied to the numbers.

Visual patterns

Help students recognize visual patterns:

Note the repeated colors in the shapes.

Using patterns to increase spatial awareness

Patterns are not just about remembering sequences, but also help strengthen spatial awareness in geometry. Understanding patterns helps learners understand how objects are related in space.

Summary

Recognizing and creating patterns is an important step in developing mathematical reasoning and spatial awareness. From simple sequences of shapes and numbers to more complex alternating patterns, these foundational skills will aid further learning in math and real-world problem-solving.

Through a variety of activities and challenges, students discover the joy of patterns, which not only makes math fun but also prepares them for more advanced concepts in the future.
