Math class isn’t usually where you’d expect a child to find their voice. For many kids, it’s about numbers, symbols, and silent calculations. But for Huhu, a once-quiet third grader, the Sino-bus Singapore Math program became an unexpected platform for developing confidence, clarity, and communication skills—the ability to express mathematical thinking clearly and logically.
Huhu’s parents first enrolled him in the program because he was struggling with word problems. “He could calculate,” his mother explained, “but he couldn’t explain how he got his answers. When teachers asked him to show his work, he would just point to the numbers and stay quiet.”
The Silence Around Math
Before joining Sino-bus, Huhu saw math as a solitary subject. He believed that as long as he got the right answer, nothing else mattered. But this mindset limited his progress. When he made mistakes, he couldn’t figure out where he went wrong. When he encountered new kinds of problems, he didn’t have the tools to talk through his confusion.
His teacher noticed this too: “Huhu was often stuck not because he didn’t understand, but because he couldn’t articulate what he didn’t understand. He’d say ‘I don’t get it,’ but couldn’t explain which part was tricky.”
How Sino-bus Turns Math Into a Language
The Sino-bus approach treats math not just as a calculation tool, but as a language of logic. The program intentionally integrates communication skillsinto every lesson. Here’s how they did it:
1. Think-Pair-Share Routine
Every class includes short sessions where students first think alone, and share with their teacher. At first, Huhu would only whisper to his teacher. But with gentle encouragement, he began speaking up.
2. Sentence Starters
Teachers provided simple phrases to help students structure their thoughts:
“I think the answer is… because…”
“I noticed a pattern when…”
“My strategy was to…”
“I disagree because…”
These frames gave Huhu safe ways to begin speaking about math.
- Show and Explain
Instead of just writing answers, students were asked to demonstrate problems using objects, drawings, or gestures. Huhu loved using colorful blocks to show how he solved problems. The physical objects gave him something to point to and talk about.
Huhu’s Expression Journey
1: Finding Safe Spaces
Huhu would only speak in a low voice at the beginning, in quiet voices. His breakthrough came when his teacher said, “I don’t understand how you did that.” For the first time, Huhu explained his thinking to someone who genuinely wanted to know.
2: Using New Tools
He began using the sentence starters without prompting. “I noticed that 15 + 7 is like 15 + 5 + 2,” he told his teacher one day. It was his first unsolicited comment in math class.
3: Asking Questions
Instead of saying “I don’t get it,” Huhu learned to ask specific questions: “I understand how to add the fractions, but I’m confused about finding the common denominator.” This helped teachers help him better.
4: Helping Others
When a classmate struggled with a multiplication concept, Huhu said, “I used to get stuck on that too. Want me to show you how I remember it?” He’d become not just a learner, but a helper.
5: Leading Discussions
During a family shopping trip, Huhu explained to his dad: “If we buy the large cereal box, it costs 20% more but gives us 40% more cereal. That’s a better deal.” His father was amazed not just by the math, but by how clearly his son explained it.
6: Confidence in Class
Huhu raised his hand to volunteer answers regularly. He even disagreed politely with his teacher once: “I think there might be another way to solve this problem.” The teacher celebrated this moment as a sign of true mathematical thinking.
The Sino-bus Methods That Made the Difference
Role-Playing
The playful context made speaking feel like a game, not a test.
Error Analysis Sessions
Teachers normalized mistakes by having students analyze wrong answers. Huhu learned to say things like, “I think where I went wrong was…” without embarrassment.
Family Involvement: Speaking Math at Home
Huhu’s parents learned to support his expression development:
Math Talk During Meals
They discussed everyday math: “If we need to double this recipe, how much milk should we add?” “What time will we arrive if we leave now and drive 60 kilometers per hour?”
Praise for Process
Instead of saying “You’re so smart,” they said, “I like how you explained that clearly” or “That was a creative way to solve the problem.”
Patient Listening
They gave Huhu time to finish his thoughts without interrupting, even when he spoke slowly or made mistakes.
The Ripple Effects: Beyond Math Class
Huhu’s new communication skills have also been applied to other fields:
Better Writing
His language arts teacher noticed improvements in how he organized essays and explained his ideas.
Stronger Friendships
He became better at expressing his feelings and resolving conflicts with words.
Leadership Emergence
He volunteered to present a science project because he felt confident explaining the data.
Teacher’s Perspective: Why Expression Matters
Ms. Li, Huhu’s Sino-bus teacher, explains: “Math expression isn’t about fancy words. It’s about making thinking visible. When students can articulate their reasoning, they deepen their own understanding and help others learn too.”
“Huhu’s success came from creating a safe environment where mistakes were welcomed, and every attempt to speak was valued.”
Huhu in His Own Words
“My favorite moment was when I explained a tricky problem to my teacher and she actually understood it. I felt like I had superpowers!”
The Science Behind the Approach
Sino-bus methods align with research on learning:
Social Learning Theory
We learn effectively by observing and explaining to others.
Metacognition
Talking about our thinking helps us become aware of and improve our learning processes.
Practical Tips for Developing Math Expression
Based on Huhu’s experience, here are actionable strategies:
Start Small
Begin with short, structured speaking opportunities like completing sentence starters.
Use Wait Time
Allow 5-7 seconds of silence after asking a question so children can gather their thoughts.
Focus on One Skill
Each week, highlight a specific expression skill like “giving examples” or “comparing strategies.”
Celebrate Courage
Praise effort in speaking up, not just correct answers.
For Parents: Bringing Expression Home
Cook Together
Reading recipes and measuring ingredients naturally creates math conversations.
Play Math Games
Games that require explaining moves or strategies encourage math talk.
Share Math Moments
Point out math in daily life and ask open-ended questions: “I wonder how many leaves are on that tree? How might we estimate?”
The Big Picture: Math as Communication
Sino-bus recognizes that mathematics is not just a set of answers but a language for describing patterns, relationships, and logical thinking. By integrating expression throughout the curriculum, they prepare students not just to calculate, but to communicate, collaborate, and think critically.
Finding Voice, Finding Confidence
Huhu’s journey from silence to expression illustrates how the right educational approach can transform not just academic skills but personal confidence. The Sino-bus program provided the tools, safety, and encouragement he needed to develop his mathematical voice.
His story tells us that communication skills are not an ancillary aspect of mathematics learning, but an indispensable part of it—it’s essential to deep understanding. When children can explain their thinking, they own their learning in powerful new ways.
As Huhu’s father observed: “The change wasn’t just about math grades. It was about seeing our son become someone who could stand up and share his ideas with the world. That confidence will serve him everywhere life takes him.”
