For Josephine Crisologo, a veteran educator with over 30 years of teaching experience, fractions used to be one of the most challenging topics to teach. For students, it’s often one of the hardest to grasp. But that changed when she discovered Frax, a game-based learning platform designed to build deep conceptual understanding of fractions.
Meeting diverse needs with Frax: A multi-grade classroom success story
Crisologo currently teaches a multi-grade classroom at Rosebud Public School in Montana, where she works with a small but diverse group of 4th, 5th, and 6th graders. “The most challenging thing I face is handling multiple levels in my classroom,” she explains. “There are different needs of my students, but I use different approaches to attend to the individual needs of every learner.”
While exploring a math organization’s website, Crisologo came across a grant opportunity for Frax. Knowing her students needed more motivation and support with fractions, she applied. Soon after, she began using Frax in her classroom. “Frax is not just fun to work with, but it’s also educational,” she says. “The learners were challenged to do the missions, which led them to ask more questions and analyze fractions in such an enjoyable way.”
A game-changer for engagement and understanding
Crisologo quickly saw the impact. “Frax became my companion in class for those learners who work fast.” She used it to keep them engaged while others were still working. “I was amazed by the effect on my learners, in a sense of having the initiative to do it even though they find difficulty in doing the mission,” she said.
The platform’s interactive missions and built-in rewards system transformed how her students approached math. “One of my students said, ‘Frax makes fractions make sense. It’s like a math video game, but I’m learning at the same time!’ That kind of excitement is rare with fractions!”
Frax also helped tackle one of the trickiest topics: equivalent fractions. “Frax made it visual and fun, which helped it finally ‘click’ for many of them,” Crisologo shares. “Students who used to struggle are now more confident and even excited to tackle problems they would have avoided before.”
More than just practice—a shift in teaching
Crisologo uses Frax in a variety of ways: during math centers, as part of blended learning rotations, and even as homework or extra practice for early finishers. “My favorite part is how Frax scaffolds instruction—every lesson builds logically, with support at just the right moments.” She’s also noticed a shift in her own teaching. “It’s influenced how I teach—I’ve adopted more visual and interactive approaches, even outside of the Frax platform.”
What about her students? They love the missions and earning rewards. Her students often say it feels like they’re playing a game rather than doing work.
Beyond academic gains, Frax has helped foster a sense of community in her classroom. “Students often discuss the levels they’ve completed and help each other understand tricky parts. It’s created a small community of learners who support one another, which is incredibly powerful.”
Advice for other educators
Crisologo encourages other teachers to give Frax a try. “You won’t regret it! Frax does a great job at filling in gaps and building up confidence. Even students who are usually reluctant in math will be drawn in. Start small, maybe with a station rotation, and you’ll quickly see how it supports your teaching.”
She also highlights how Frax supports equity. “Because the platform is intuitive and accessible, even students with different learning needs or language backgrounds are able to participate fully. It levels the playing field so every student gets the chance to succeed.” Crisologo believes that if more schools had access to Frax, the impact would be widespread. “It’s not just a supplement. It’s a tool that helps shape how we think about effective, student-centered math instruction.”
Experience the Frax difference with your students by taking a free trial. Like Crisologo said, you won’t regret it.
About Josephine Crisologo
Josephine Crisologo has been a dedicated educator for over 30 years. She is an experienced elementary teacher who earned her Bachelor's degree in Elementary Education with a specialization in Mathematics from the National Teachers College in the Philippines. She also completed 36 units toward her Master’s degree. Josephine spent 22 years teaching mathematics at a Chinese school in Manila, where she also served as a math coach for nearly her entire tenure. Under her guidance, her students regularly participated in annual math competitions. Following her time at the Chinese school, she transitioned to a public school, where she taught science to six sections of 5th-grade students, each with 35–40 learners. After four years in the public school system, Josephine moved to the United States and joined Rosebud Public School, where she currently teaches. She is passionate about education and remains eager to embrace new trends and innovations in teaching.
