Exploring Number Sequences: Twos, Threes, and Fives

Learning objective

Learning Objectives

At the end of the lesson, you will be able to create, describe, and continue increasing and decreasing number sequences using twos, threes, and fives.

What do you already know about number sequences?

Curriculum Links

Aligned with ACARA Year 2 Mathematics: Number and Algebra, focusing on recognising and exploring patterns in numbers.

Materials Needed

Dice, number lines, counters, and a board or chart paper for demonstrating sequences.

Introduction to Number Sequences

Number sequences are lists of numbers that follow a certain rule. Let's explore sequences using twos, threes, and fives.

Exploring Twos

Roll a dice to find starting points. Count by twos to create a sequence. Write your sequence on the number line.

Exploring Threes

Use the dice to select a starting point. Count forward and backward by threes. Note the sequence on the number line.

Exploring Fives

Choose a starting point with the dice. Count by fives up and down the number line. Observe the pattern.

Activity: Sequence Challenge

Each group rolls the dice and creates a sequence using twos, threes, or fives. Share your sequences with the class.

Describing Sequences

Describe the pattern and rule of your sequence. How does it start, and how does it grow or shrink?

Continuing Sequences

What comes next in your sequence? Can you predict future numbers? Extend your sequence further.

Review and Reflect

What rules did you discover? How do number sequences help us in maths? Share your thoughts.

Conclusion

Great job exploring sequences today! Keep practising recognising patterns in numbers and sequences at home.
