The Math Center
From counting to fractions: how elementary math actually develops, why it breaks where it breaks, and the five-minute games that fix it.
Elementary math is a tower: number sense under facts, facts under operations, operations under fractions — and nearly every "sudden" math struggle is a lower floor asking for attention. The guides in this center map the whole tower, floor by floor: what each skill really is, how it's supposed to develop, the classic errors decoded (why 34 − 18 keeps equaling 24), and the games that build each layer better than worksheets ever have.
If your child is struggling right now, start with the guide closest to the symptom — each one includes the look-underneath diagnosis, because the presenting problem and the actual problem are usually one floor apart. And when a season of games isn't enough, my math tutoring page describes how I find the true floor and rebuild it.

Math skills by grade, TK through 5th
Elementary math is a tower — each floor stands on the one below. Here's what gets built each year, which cracks are cosmetic, and which ones spread.
Read the guideBuilding math confidence
'I'm bad at math' is a story children tell, not a fact about their brains — and stories can be rewritten. Here's how confidence is actually built, lost, and rebuilt.
Read the guideNumber sense: the foundation under everything
Number sense is the difference between doing math and understanding it — and it's the root cause behind most later math struggles. Here's what it is and how it grows.
Read the guideHow children actually learn to add
Addition isn't memorized — it's constructed, through a predictable ladder of strategies. Knowing the ladder tells you exactly how to help at every rung.
Read the guideTaming subtraction (yes, it's genuinely harder)
Subtraction reliably lags addition, and the classic 'borrowing' errors have one root cause. Here's why it's harder, the strategies that tame it, and the fix for regrouping.
Read the guideMultiplication that sticks
Times tables learned as pure sound evaporate every summer. Times tables built from arrays and strategies last forever. Here's the sequence — and the flashcard-purgatory rescue.
Read the guideDivision: fair shares to long division
Division is multiplication wearing a question mark — and children who see that connection skip most of the struggle. Here's the path from sharing cookies to long division.
Read the guideFractions, finally explained
Fractions are where elementary math's IOUs come due — the single most common crisis point I tutor. Here are the three ideas that make them sensible, and the tools that rebuild.
Read the guideMaking sense of word problems
'He can do the math — he just can't do word problems' is one of the most common sentences in tutoring. Here's what's actually breaking, and the fix that isn't keyword tricks.
Read the guideMental math, taught on purpose
Mental math isn't a gift some kids have — it's a small set of nameable strategies plus number sense. Here's the set, in teachable order, and the car games that build it.
