Olaseni Fadipe, Ph.D., is a mathematics educator, author, and creator of Multiplication Flip. His work focuses on helping children and families move beyond memorizing mathematical procedures toward deeper understanding, stronger number sense, and confident problem solving.
Helping mathematics make sense
Over years of teaching mathematics, I kept seeing the same pattern: students could often follow a procedure without fully understanding the mathematics underneath it.
They could remember a rule, repeat an algorithm, or reproduce an example, but unfamiliar problems could quickly make that knowledge feel fragile.
That led me to a question that continues to shape my work:
How can we help learners make sense of mathematics before asking them to remember it?
My answer has increasingly centered on conceptual understanding, visual models, multiple representations, number relationships, and flexible problem solving.
When learners can see how ideas connect, mathematics becomes less about remembering isolated rules and more about reasoning from what they already know.
How I think about learning mathematics
Good mathematics learning should help students understand, connect, represent, reason, and eventually work independently.
Understanding Before Memorization
Fluency matters, but it becomes more durable when learners understand the ideas and relationships underneath the facts and procedures they use.
Multiple Representations
A mathematical idea can often be represented with pictures, symbols, patterns, words, tables, graphs, or concrete models. Seeing those connections builds deeper understanding.
Flexible Thinking
Learners should develop more than one way to approach a problem and learn to use what they already know to figure out what they do not yet know.
Confidence Through Progress
Mathematical confidence grows through understanding, carefully sequenced challenges, useful practice, and repeated experiences of making sense of difficult ideas.
Multiplication Flip
Multiplication Flip grew from the belief that children should not have to treat every multiplication fact as something new to memorize.
The approach uses patterns, arrays, decomposition, visual models, number relationships, and carefully sequenced practice to help learners build harder facts from facts they already understand.
The larger goal is not simply multiplication recall. It is helping children become stronger and more flexible mathematical thinkers.
