Mathematics - Term 4 - Week 3

Patterns are sequences that repeat in a predictable way. They can be made using numbers, shapes, or colors. For example, a simple pattern could be red, blue, red, blue. In mathematics, we can also create patterns using numbers, such as 2, 4, 6, 8, where each number increases by 2. Today, we will explore how to identify and create our own patterns.

Let's create a number pattern together. Start with the number 5. If we add 3 each time, our pattern will be: 5, 8, 11, 14. Notice how each number increases by 3. Now, if we wanted to write the next three numbers in this pattern, we would continue: 17, 20, 23. This shows how we can extend a number pattern by consistently adding the same value.

Now, let's identify some patterns together. Look at this sequence: 10, 20, 30, __, __. What do you think the next two numbers are? (Pause for responses). Yes, the next numbers are 40 and 50 because we are adding 10 each time. Let's try another one: 1, 3, 5, __, __. The next numbers are 7 and 9, as we are adding 2 each time. Great job!

Now it's your turn! Create your own number pattern using the number 4. Decide how much you want to add each time and write down the first five numbers in your pattern. After that, share your pattern with a partner and see if they can identify the rule you used. Remember to think about how you can extend your pattern!

• 8
• 7
• 9
• 10

Answer: 8

The pattern adds 2 each time, so after 6 comes 8.

• 1, 2, 3, 4
• red, blue, red, blue
• cat, dog, fish
• apple, banana, orange

Answer: red, blue, red, blue

This sequence repeats colors in a predictable way.

Answer: 5, 10, 15, 20

The pattern adds 5 each time, starting from 5.

• A
• B
• C
• D

Answer: A

The pattern alternates between A and B.

Answer: Add 5 each time.

The pattern increases by 5.

• 15
• 13
• 18
• 21

Answer: 13

The pattern adds 3, so the next number should be 15.

Answer: circle

The pattern alternates between circle and square.

• 10
• 12
• 16
• 14

Answer: 16

The pattern doubles each time, so after 8 comes 16.
