Active learning ideas

Identifying and Extending Number Patterns

Active learning helps students grasp number patterns by letting them see, touch, and talk about the sequences they create. When children build patterns with blocks or hunt for them around the room, they connect abstract rules to concrete experiences, which strengthens both memory and reasoning.

• 35 min · Pairs

Pattern Blocks: Growing Sequences

Provide linking cubes or pattern blocks. Students create sequences like add one more each time, then extend to the tenth term and write the rule. Pairs swap creations to predict and verify. Discuss strategies as a class.

How can we predict the tenth term in a pattern without drawing all the steps in between?

Facilitation Tip

During Pattern Blocks: Growing Sequences, circulate and ask groups, 'How does the shape change from one step to the next? Can you describe that change as a rule?'

What to look for

Provide students with three different number sequences (e.g., 5, 10, 15, 20; 3, 9, 27; 100, 90, 80). Ask them to write the rule for each sequence and then calculate the next two terms for one of them.

Number Hunt: Classroom Patterns

Hide number sequence cards around the room, such as 5, 10, 15 or 1, 3, 9. Small groups find cards, extend the pattern to five terms, and identify the rule. Groups present findings on a shared chart.

Analyze different types of number patterns (e.g., arithmetic, geometric).

Facilitation Tip

For Number Hunt: Classroom Patterns, provide clipboards and pencils so students can record sequences in their own words before sharing with the class.

What to look for

Give each student a card with a sequence like 4, 8, 12, 16. Ask them to write down the rule and predict the 8th term. Collect these to gauge individual understanding of rule application.

Prediction Relay: Term Challenges

Write sequences on the board, like 7, 14, 21. Teams line up; first student says the next term, next adds another, until the tenth. Correct teams earn points; review rules afterward.

Construct a rule that describes a given number pattern.

Facilitation Tip

In Prediction Relay: Term Challenges, give each team a time limit of two minutes per sequence to encourage quick thinking and discussion.

What to look for

Present a complex pattern, perhaps one that alternates operations (e.g., add 2, multiply by 3, add 2, multiply by 3). Ask students: 'How is this pattern different from the ones we've seen? What steps would you take to find the rule and predict the next term?'

Rule Maker Cards: Match Game

Prepare cards with sequences, next terms, and rules. Students in pairs match them, then create their own sets for others to solve. Shuffle and replay for practice.

How can we predict the tenth term in a pattern without drawing all the steps in between?

Facilitation Tip

With Rule Maker Cards: Match Game, limit the cards to 10 per student to keep the activity focused and prevent overwhelm.

What to look for

Provide students with three different number sequences (e.g., 5, 10, 15, 20; 3, 9, 27; 100, 90, 80). Ask them to write the rule for each sequence and then calculate the next two terms for one of them.

A few notes on teaching this unit

Start with concrete patterns before moving to symbols. Students need to see that 2, 4, 8, 16 is not just 'adding 2' but 'multiplying by 2,' which requires them to notice the relationship between terms. Avoid rushing to formal notation; let students verbalize rules first. Research shows that students who describe patterns in their own words before writing them down develop stronger algebraic intuition later.

By the end of these activities, students should confidently describe pattern rules, extend sequences beyond the given terms, and justify their thinking using clear language. They should also begin to recognize the difference between additive and multiplicative patterns without prompting.

Watch Out for These Misconceptions

• During Pattern Blocks: Growing Sequences, watch for students who assume all patterns grow by addition. Redirect them by asking, 'What happens to the blocks when you follow the rule? Could you describe the change as multiplying instead?'

  Have students rebuild the same sequence twice, once using addition and once using multiplication, to compare which rule matches the visual growth of the blocks.

• During Prediction Relay: Term Challenges, watch for students who guess the next term without explaining their choice. Redirect them by asking, 'How did you decide the next number? What rule did you use to get there?'

  Require students to state their rule aloud before writing the next term, and have peers verify or challenge the rule based on the sequence.

• During Number Hunt: Classroom Patterns, watch for students who confuse the position of a term with its value. Redirect them by asking, 'If the third term is 12, what does the '3' tell you about how the pattern grows?'

  Ask students to record each term with its position number (e.g., 3rd term: 12) on a table, then highlight the rule column to show how position relates to the term value.
