The day we measured the classroom

Practical Measurement Activities That Turn into Mini Adventures

What starts as a simple measurement activity can quickly turn into a full-blown classroom adventure, especially when rulers, tape measures, and teamwork are involved.

It was a Grade 6 math lesson on perimeter and area. I wanted students to see measurement as more than just numbers in a textbook, so I told them:

“Today, we’re going to measure the entire classroom.”

There was an immediate buzz. Suddenly, math was no longer about worksheets, it was about exploring our own space.

We split into groups, armed with rulers, measuring tapes, and clipboards.

One group started at the back wall, another tackled the windows. In contrast, a third group became fascinated with measuring every single desk. Pretty soon, questions started flying.

“Do we measure around the teacher’s table, or count it as part of the floor space?”

“What about the carpet? Does that change the area?”

A group accidentally measured in feet instead of centimeters, which led to a quick unit conversion lesson.
Another group discovered a corner wasn’t perfectly square, sparking a discussion about real-world geometry. Someone even measured the door height “just in case we need to bring in a giant pizza.”These were exactly the kinds of questions that made the activity come alive.

By the end, the students didn’t just know the perimeter and area of the classroom, they understood why we measure, the importance of accuracy, and how math connects directly to the world around them.

What could have been a dry lesson turned into laughter, teamwork, and authentic problem-solving.

Handling Criticism Constructively

If I’m being honest, I used to hear the word criticism and immediately brace for impact. My heart would race, my brain would go on defense mode, and all I could think was, “Oh no… what did I do wrong?” Criticism doesn’t have to crush you. In fact, if you can handle it constructively, it can become your best teacher. Here’s the framework that helped me turn feedback from a personal attack into a professional upgrade. But over the years, especially through teaching, research, and plenty of presentations, I’ve learned something important: The 5-Step Calm Response Framework Pause - Separate - Ask - Decide - Reflect Pause Before Reacting When someone gives you feedback, your first job is not to respond; it’s to breathe. Literally. Inhale for 4 seconds, exhale for 4. This little pause stops you from blurting something defensive and helps you actually hear what’s being said. “Let me hear this fully before deciding what i...

The Day the Equation Clicked

“Miss, I finally get it!” Those five words lit up my entire week. We were deep into linear equations, a topic that usually triggers a collective groan. I had introduced the concept using a real-life scenario about sharing snacks among friends (because who doesn’t like food math?). Some students were engaged, but one in particular, let’s call him Tom, sat quietly, eyes down, pencil untouched. Halfway through the lesson, I handed out mini whiteboards. “Explain the rule in your own way,” I told them. A few minutes later, Tom called me over and quietly said, “Miss, I finally get it.” He showed me a simple drawing of two snack packets being shared equally. It wasn’t textbook-perfect, but it was his understanding, in his own words. We high-fived. He smiled. And in that moment, the equation wasn’t just solved, it clicked . Why This Moment Matters It reminded me that understanding doesn’t always look the same for every stu...

The 5E Model - A Teacher's Secret Weapon

Let’s face it. Sometimes teaching feels like a tornado! Students can get distracted or zone out, but that’s where the 5E model comes to the rescue! This simple and effective framework turns any lesson into an engaging adventure: This simple and effective framework turns any lesson into an engaging adventure: Engage – Kick things off with a fun question or story that grabs their attention. Explore – Let students dive in with hands-on activities or group work, giving them the chance to play and discover. Explain – Help them connect the dots by guiding them through the key concepts. Elaborate – Challenge them with some deeper tasks that get those wheels turning! Evaluate – Check in on what they've learned in a friendly and supportive way no stress involved! With the 5E model, lessons become exciting journeys, and trust me, it makes teaching a whole lot more fun for us too!
