Number Patterns (Addition/Subtraction)

Children learn number patterns best when they can see, touch and talk about what they observe. With addition and subtraction patterns, active movement and visual sequences make the rule come alive in ways that worksheets alone cannot.

Pattern Chain Relay

Students work in pairs to build a paper chain where each link has a number following an addition or subtraction rule, like starting at 5 and adding 3 each time. One student adds a link, passes to partner for the next. The class checks the complete chain.

Analyze a number sequence to determine the rule that generates it.

Facilitation Tip

For Pattern Chain Relay, prepare a set of number cards taped to the floor so students can physically step on each number while reciting the pattern aloud.

What to look for

Write the sequence 5, 10, 15, 20 on the board. Ask students: 'What is the rule for this pattern?' and 'What are the next two numbers?' Observe student responses and note who can correctly identify the rule and predict the next terms.

Missing Number Puzzle

Provide worksheets with incomplete sequences like 3, _, 9, 12. Students fill gaps individually, then share rules in small groups. Discuss why subtraction patterns skip numbers.

Predict the next numbers in a sequence like 2, 4, 6, 8...

Facilitation Tip

During Missing Number Puzzle, give students colour pencils so they can circle the missing number and write the rule above the sequence for easy checking.

What to look for

Give each student a card with 'Start with 7, add 4'. Ask them to write down the first five numbers in this pattern. Collect the cards to check their ability to construct a pattern.

Create Your Pattern

Each student draws a number pattern on a chart paper, such as starting from 10 and subtracting 2. They present to the class, who predicts the next three numbers.

Construct a number pattern that increases by 3 each time, starting from 10.

Facilitation Tip

In Pattern Clap Game, pair students so one claps the pattern while the other writes it down, ensuring every child participates.

What to look for

Present two sequences: 3, 6, 9, 12... and 20, 18, 16, 14.... Ask students to work in pairs and explain to each other: 'How are these patterns different?' and 'What is the rule for each?' Listen for clear explanations of addition versus subtraction.

Pattern Clap Game

Teacher calls a starting number and rule, like '10, add 2.' Whole class claps and shouts numbers in unison, speeding up to test recall. Vary with subtraction.

Analyze a number sequence to determine the rule that generates it.

What to look for

Write the sequence 5, 10, 15, 20 on the board. Ask students: 'What is the rule for this pattern?' and 'What are the next two numbers?' Observe student responses and note who can correctly identify the rule and predict the next terms.

A few notes on teaching this unit

Start with concrete objects such as number cards or counters to build the first few terms of the pattern. Once the rule is clear, move to abstract numbers. Avoid rushing to symbols before students can verbalise the pattern in words. Research shows that children who describe patterns aloud before writing them down develop stronger logical structures.

Students will confidently state the rule for a given pattern, extend the sequence by at least two more terms, and create their own increasing or decreasing pattern with clear steps. They will also explain differences between addition and subtraction patterns to a partner.

Watch Out for These Misconceptions

• During Pattern Chain Relay, watch for students who assume every pattern goes up and never down.

  Pause the relay after a decreasing pattern like 12, 9, 6 and ask, 'How did the rule change here?' Have them step back two numbers to see subtraction in action.

• During Create Your Pattern, watch for students who write only one step of the rule instead of a full sentence.

  Ask them to read their pattern aloud while pointing to each card; if they say, 'I added 5', ask them to write the full rule: 'Start with 3, add 5 each time' on their sheet.
