Multiples and Number SequencesActivities & Teaching Strategies
Active learning builds deep number sense with multiples and sequences. When students manipulate objects, draw models, and collaborate, they move from memorizing steps to understanding why patterns repeat. This hands-on work turns abstract rules into concrete discoveries that stick.
Learning Objectives
- 1Calculate the first ten multiples for any given whole number up to 100.
- 2Identify the lowest common multiple (LCM) of two numbers up to 12, using listing or skip counting strategies.
- 3Explain the pattern observed in a sequence of multiples, describing the rule as repeated addition or multiplication.
- 4Solve word problems involving repeating events by applying the concept of common multiples.

Small Groups: Multiples Tower Challenge
Provide counters or linking cubes to small groups. Instruct students to build towers for multiples of a given number, such as levels of 4, 8, 12 cubes. Have them label heights, extend to 5 terms, and share growth rules with the class.
Prepare & details
How do you list the multiples of a number, and what pattern do they follow?
Facilitation Tip: During Multiples Tower Challenge, circulate and ask groups to predict the next block before they build, reinforcing the fixed increment rule.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Pairs: LCM Path Game
Pairs draw number lines for two numbers like 6 and 8. They mark multiples of each, shade common ones, and circle the lowest common multiple. Discuss why it is smallest and solve a related word problem on schedules.
Prepare & details
What are common multiples, and how do you find the lowest common multiple of two numbers?
Facilitation Tip: For the LCM Path Game, set a timer so pairs must move quickly, forcing them to rely on multiples rather than trial and error.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Whole Class: Pattern Parade
Students line up in class formation representing a sequence, such as multiples of 3 with claps or steps. Extend the pattern by adding participants. Record the sequence on board and describe the rule as a group.
Prepare & details
Can you use multiples to solve a word problem about events that repeat at regular intervals?
Facilitation Tip: In Pattern Parade, assign each student a unique starting number so the whole class sees how different sequences align or miss each other.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Individual: Shape Sequence Sketch
Each student sketches geometric shapes growing by multiples, like triangles with 2, 4, 6 dots. Label the sequence, predict the 6th term, and write the rule. Share one with a partner for feedback.
Prepare & details
How do you list the multiples of a number, and what pattern do they follow?
Facilitation Tip: For Shape Sequence Sketch, provide tracing paper so students can overlay shapes to verify consistent spacing before drawing.
Setup: Wall space or tables arranged around room perimeter

Teaching This Topic
Teach multiples as repeated groupings first, then as number sequences, so students see both the count and the pattern. Avoid rushing to the algorithm for LCM; let students list and compare multiples until they notice the shared jump. Use language like 'every third block' or 'one more set of five' to anchor the concept in concrete actions. Research shows that students who generate their own examples before formal rules develop stronger number flexibility.
What to Expect
By the end of these activities, students will confidently list multiples, spot patterns in sequences, and find lowest common multiples without guessing. They will explain their reasoning using clear language and visual evidence from their work. Collaboration will reveal misconceptions through peer feedback and shared problem-solving.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the LCM Path Game, watch for students who multiply the two numbers immediately without listing multiples first.
What to Teach Instead
Have pairs pause their game and list the first five multiples of each number on their game board side-by-side, then circle the first match to redirect their thinking.
Common MisconceptionDuring Multiples Tower Challenge, some students may stop building after a few blocks, assuming the pattern changes.
What to Teach Instead
Ask groups to add three more blocks and explain how they know the next one fits, reinforcing the fixed increment through physical extension.
Common MisconceptionDuring the LCM Path Game, students may confuse common multiples with averages, like thinking 4 and 6 share 5.
What to Teach Instead
Use the game’s Venn diagram spaces to sort exact multiples only; prompt pairs to test 'Is 5 a multiple of 4? Is it a multiple of 6?' to correct the error.
Assessment Ideas
After Pattern Parade, display a sequence like 8, 16, 24, 32, 40. Ask students to name the rule and the next three terms, collecting responses on mini whiteboards to check understanding.
During LCM Path Game, ask each pair to write the LCM of their assigned numbers and one sentence explaining how they found it, collecting tickets to assess both accuracy and reasoning.
After Shape Sequence Sketch, pose the baker’s batch problem and facilitate a whole-class discussion, noting which students reference multiples or sequences to solve it and how clearly they articulate their steps.
Extensions & Scaffolding
- Challenge students to find three numbers whose LCM is 60, then design a real-world scenario (e.g., bus schedules) for their answer.
- For struggling learners, provide a partially filled multiples chart and ask them to extend only one sequence at a time before comparing.
- Give extra time for students to create a number sequence art project using multiples of 3, 4, and 5, coloring patterns to reveal overlaps visually.
Key Vocabulary
| Multiple | A multiple of a number is the result of multiplying that number by any whole number. For example, the multiples of 3 are 3, 6, 9, 12, and so on. |
| Common Multiple | A common multiple of two or more numbers is a number that is a multiple of each of those numbers. For example, 12 is a common multiple of 3 and 4. |
| Lowest Common Multiple (LCM) | The smallest positive number that is a multiple of two or more numbers. For example, the LCM of 4 and 6 is 12. |
| Number Sequence | A series of numbers that follows a specific pattern or rule, often involving addition or multiplication. |
