How this Queensland Dad Revolutionised Maths Education with “Learning Through Doing”
Meet Guy — Educator Turned Entrepreneur
Guy Constable isn’t your typical maths teacher. As the founder of Learning Through Doing (LTD), he’s made it his mission to revolutionise how maths is taught in classrooms.
LTD creates hands-on resources that help teachers bring maths to life, making it engaging and accessible for students. That’s one half of the equation. The other is Guy’s second venture, The Mathematics Guy (TMG), a tutoring business that focuses on practical, fun, screen-free learning.
Together, the two brands create a comprehensive maths education ecosystem that is nurturing the minds of tomorrow’s leaders and innovators.
The backstory: Turning a passion into a thriving business
Guy founded LTD in 2018 after realising the lack of engaging maths resources available for teachers. His goal was simple: make maths fun and hands-on, so students aren’t stuck in a traditional learning environment.
“When I think about what motivates me, I reflect on my own kids. I’d hate for their classroom experiences to be one where they’re just sitting at desks being delivered a PowerPoint or a lecture”
LTD quickly grew from a small startup into a trusted resource used by over 6,000 teachers across Australia and New Zealand, with plans to expand into the UK. The hands-on approach resonated with educators who were tired of the same old textbook methods. By providing ready-to-use materials that make maths interactive, LTD has empowered teachers to bring creativity and confidence into their classrooms.
But as the business grew, so did the challenges. Guy found himself stretched thin, managing marketing, developing products, and overseeing the day-to-day operations. That’s when he realised he needed help to scale his vision.
His products and services were fantastic, but there was only so much he could do himself. Guy knew that to unlock the next phase of growth, he needed a partner. Enter: Megaphone.
Mixing education with eCommerce
“Originally, we were primarily a service business, but we saw a need for products that support hands-on learning. Many of our products are new to the market, and that’s really exciting because teachers are getting to work with high-impact visual models that engage kids in learning mathematics,” explains Guy.
Spotlighting the incredible ‘Term 4 Free’ Campaign
One of LTD’s most successful initiatives was the ‘Term 4 Free’ campaign, which offered schools a chance to trial LTD’s resources in the final term of the year. The idea was to give teachers a no-risk opportunity to experience the benefits of hands-on maths teaching, right when they needed it most.
“We spent $7,000 on promoting it and turned over $85,000 that year from that campaign. And that’s not just a one-off. We’re looking at recurring revenue of over $400,000 in the next five years from the schools that continue to use our content.”
With the Megaphone team working hard behind the scenes (led by Andy, Rhani and Ellie), the campaign brought in over 1,000 school leads and onboarded more than 150 schools in 2024 alone. The flow-on effect can’t be understated—this strategic approach allowed LTD to build lasting relationships with schools and keep them engaged year-round.
Megaphone’s involvement wasn’t just about running ads though; it was about creating a comprehensive plan to keep LTD top-of-mind for teachers. This included initiatives like..
- Free Planning Documents at the start of the school year to help teachers get organised.
- Masterclasses that provided ongoing support and training to enhance teaching methods.
- Resource Giveaways and trials to keep LTD’s offerings in front of educators when they were most receptive.
These efforts meant that LTD wasn’t just a product teachers used; it became a trusted partner in the classroom.
But how exactly did the Megaphone team execute this?
In 3 steps, here’s how Megaphone
- Tailored campaign planning: Megaphone didn’t just focus on one-off promotions. They built a year-round strategy that kept LTD front-of-mind for teachers, especially during key decision-making times.
- Creative content that stood out: Megaphone’s team crafted engaging ads, skits, and educational videos that captured the essence of LTD’s hands-on approach. And Guy absolutely loved it. These creatives helped bridge the gap between traditional teaching and the dynamic, practical approach LTD promotes.
- Data-Driven Targeting: the Megaphone experts dug deep into LTD’s data, using insights to fine-tune audience targeting and maximise engagement. By leveraging look-alike audiences and consistently refreshing ad creatives, viewer fatigue was avoided and momentum stayed strong.
Results
Since teaming up with Megaphone, LTD has seen phenomenal growth.
“After one year, our revenue jumped from $780,000 to $1.35 million, and this year, we’re on track to generate over $2 million,” says Guy.
Working with Megaphone has not only driven sales but also freed up Guy’s time to focus on what he loves—creating impactful learning experiences.
“Before Megaphone, I was coming up with the marketing strategies and the copy myself. Now, they take care of all those little things, which means I can zero in on the stuff that I’m passionate about.”
The impact of LTD isn’t just financial. It’s reshaping how maths is taught in classrooms, giving teachers the tools they need to deliver lessons that students actually enjoy.
So, where to next for Learning Through Doing?
Guy’s journey from educator to entrepreneur has been transformative, with LTD leading the way in how maths education is approached in schools. And while the numbers are incredible, it’s still just the beginning. Guy has big plans to expand into new markets and continuously innovate — LTD is set to redefine maths education for future generations.
And with Megaphone as a strategic partner, Guy knows he has the support he needs to keep pushing boundaries.
“They’ve been incredible at finding opportunities to engage teachers and schools all year round,” says Guy. “Megaphone has been the turning point in my business, and it’s exciting to see what’s next.”
