Counting in Tens to 100Activities & Teaching Strategies
Active learning works well for counting in tens because students need to see and feel the pattern of tens to grasp its structure. Movement and hands-on materials reinforce the skip-counting rhythm, making abstract numbers concrete. This approach builds confidence as students notice consistent patterns in the numbers they count.
Learning Objectives
- 1Identify the sequence of numbers when counting forward by tens up to 100.
- 2Calculate the next number when counting forward by tens from any given multiple of ten up to 100.
- 3Demonstrate counting backward by tens from a given multiple of ten down to 10.
- 4Explain the pattern observed when counting by tens, noting the consistent digit in the ones place.

Bundle Builders: Straw Tens
Provide drinking straws or popsicle sticks. In small groups, students bundle them into sets of 10, then count forward from a starting bundle like 30 to 100. Switch to backward counting from 80, recording totals on group charts. Discuss patterns observed.
Prepare & details
What pattern do we notice when counting in tens?
Facilitation Tip: During Bundle Builders, circulate and ask students to explain how many tens they have bundled and how many ones remain loose.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Number Line Relay: Tens Race
Mark a floor number line from 0 to 100 in tens. Pairs take turns hopping from a starting multiple of 10, calling out numbers forward or backward. First pair to reach end or zero wins a point. Rotate starters.
Prepare & details
How does counting in tens help us count large groups of objects quickly?
Facilitation Tip: In Number Line Relay, pause after each round to have students chant the sequence they just ran together.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Ten-Frame Flip: Pattern Cards
Prepare cards with ten-frames showing multiples of 10 up to 100. Students in pairs flip cards and count forward or backward in sequence. Use dry-erase boards to extend chains beyond 100 if ready. Share longest chains class-wide.
Prepare & details
Can we count backward in tens? How?
Facilitation Tip: For Ten-Frame Flip, model how to record each flip as an equation, such as 30 + 10 = 40, to connect counting to written math.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Market Count: Group Shopping
Set up a class market with items in tens (e.g., 10 pencils per pack). Small groups 'shop' by counting packs forward/backward to total 100 items. Tally and compare group totals.
Prepare & details
What pattern do we notice when counting in tens?
Facilitation Tip: At Market Count, provide a limited number of items so students experience the need to count in tens to tally totals efficiently.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
Start with concrete materials like straws or linking cubes to build tens, as research shows this helps students internalize place value. Move to representational tools like number lines only after students can count and group objects in tens confidently. Avoid rushing to abstract symbols before students understand the grouping concept. Use choral counting and partner turns to build fluency and reduce anxiety about mistakes.
What to Expect
Successful learning looks like students counting forward and backward by tens without hesitation, recognizing the zero pattern in the ones place. They should explain how grouping objects in tens helps count large quantities quickly. Partner discussions should include clear reasoning about the patterns they observe.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Bundle Builders, watch for students counting each straw one by one instead of grouping by tens.
What to Teach Instead
Prompt students to bundle straws in groups of ten and physically move the bundle past the next ten while skipping the ones place aloud. Ask, 'How many tens did you move? What number comes next?' to redirect their attention.
Common MisconceptionDuring Number Line Relay, watch for students losing track of the direction when counting backward.
What to Teach Instead
Have students point to the number line with their finger while chanting backward steps together. Use a colored arrow on the line to mark direction and ask, 'Is the next number bigger or smaller than the one before?'
Common MisconceptionDuring Bundle Builders or Ten-Frame Flip, watch for students treating tens as single units without understanding they represent ten ones.
What to Teach Instead
Ask students to dismantle a bundle or flip a ten-frame back to ones, then recount to show ten individual units. Use linking cubes to snap apart and reassemble, emphasizing the composition during sharing time.
Assessment Ideas
After Bundle Builders, show a card with 50. Ask students to write the next three numbers when counting forward and the previous three numbers when counting backward. Collect their responses to check for accurate zero patterns.
During Market Count, present 60 counters bundled in six groups of ten. Ask, 'How many groups of ten do you see? How would you count these quickly? What do you notice about the last digit of each number as you count by tens?'
After Number Line Relay, give each student a worksheet with two sections: Section 1 starts at 30 and counts forward to 100, Section 2 starts at 80 and counts backward to 10. Students complete both sequences to demonstrate fluency.
Extensions & Scaffolding
- Challenge students to count backward from 100 by tens starting at any multiple of ten they choose during Number Line Relay.
- Scaffolding: Provide a partially completed number line strip during Bundle Builders for students to fill in missing tens and connect to their bundles.
- Deeper exploration: Have students create their own counting pattern cards using Ten-Frame Flip materials, then exchange with peers to solve sequences starting at different points.
Key Vocabulary
| tens | A group of ten ones. When we count in tens, we are counting groups of ten. |
| multiple of ten | A number that can be divided by ten with no remainder, such as 10, 20, 30, and so on, up to 100. |
| forward | Moving in a direction that increases in value, such as counting 10, 20, 30. |
| backward | Moving in a direction that decreases in value, such as counting 50, 40, 30. |
Suggested Methodologies
Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
