Approaches to math education
Traditional versus Discovery math education models at Canadian private schools


Traditional math typically teaches the method or algorithm first, and then moves to applications. Students practice these algorithms via repetition and drills so they build foundational procedural mastery. The traditional approach views math learning as building on prior knowledge—each skill acts as a “brick” supporting the next. In this model, students are first given a tool, then challenged to apply it through increasingly complex tasks. In that sense, traditional math emphasizes procedural understanding before conceptual or applied thinking.
Discovery math reverses the sequence: it often begins with an intriguing problem and guides students toward “discovering” a method of solution. The aim is to root algorithms in meaningful context and challenge students to reason from first principles. Often linked with the “Chicago Math” movement and Everyday Math (grades 1–6), Discovery Math spends less class time drilling algorithms and more time engaging students in novel problems and deeper understanding. Here, conceptual and applied understanding are foregrounded, with procedural skills coming afterward.
Balanced math programs strive to integrate both traditional and discovery methods. In many cases, this hybrid approach attempts to leverage the strengths of both—skill development and conceptual understanding—in a complementary way.
Kim Langen, CEO of Spirit of Math Programs:
There are many new ideas that have been tried in mathematics education, much of which has been developed to ‘unpack’ the understanding of mathematics, instilling rich experiences into the classroom. Unfortunately, in an attempt to do this, many teachers have focused entirely on activities for learning and creative solutions, without critically examining what outcomes can be used to apply their knowledge to build skill sets. I call this ‘staying in the sandbox without discovering what can be used to build a bigger castle.’;
What went wrong was that teachers who went to the extreme of this thinking will not tell kids that they got a wrong answer: they believed that the creative approach was more important than the skills and correct answers. We want our kids to be innovative thinkers, but they also need to be able to use their skills to develop stronger logical thinking skills. Skill development was dropped, and so were the automaticity of basic number facts. Calculators and computers, it was thought, could do all the calculations and processes.
It is clear that skills, automaticity of number facts and processes are needed; however, the innovative construction of ideas is also needed. Asia and South Asia focus on skills, drills and procedures, and yet, they are looking to North America for their new ideas. They realize that they are skewed in the other direction. What really went wrong is that people on both sides of the world have gone too far in one direction or another, leaving many good qualities of math education behind.

Hanna Gernega, Oxford Learning High Park:
… there is nothing wrong with memorizing the multiplication table. We also tend to rush, and rarely do students stay on the same concept more than two weeks. It is not nearly enough time to learn and apply new knowledge. Each concept needs to be explained with the connection to the real life through problem solving. We need to make sure that previously taught concepts are constantly being used and refreshed while teaching something new. … the countries which do it right, they all have the same approach: teach and practice Math every day for few hours and constantly use and apply it in real life activities.
