Keep the habit. Upgrade the science.
Kumon proved that daily practice works. Delta keeps that discipline — and adds what memory research has learned since: review timed to forgetting, real explanations, instant feedback, and every subject in one plan.
We believe what Kumon believes
Short daily practice. True mastery before moving on. Start where your child actually is, not where the grade says they should be. Kumon got these right sixty years ago — Delta builds on them.
About 20 focused minutes. Momentum beats marathons — the streak is the strategy.
A concept isn't “done” because the unit ended. It's done when your child owns it.
A diagnostic finds each child's real starting line — then practice stays at their edge.
Same discipline, different engine
Kumon's engine is repetition: worksheets until it's automatic. Delta's engine is memory science: the right question at the right moment, with the why built in.
| What matters | Delta After School | Kumon |
|---|---|---|
Review timing When does old material come back? | ✓ Timed to forgetting Each concept returns right before it fades, at growing intervals — so it sticks for good. | — Repetition by level Repeat the level until fast, then advance. What's behind you rarely comes back. |
Understanding the why Concepts, not just procedures | ✓ Built in Kids predict before they're taught, connect ideas, and explain concepts back in their own words. | — Not the focus Worksheets build execution. The “why” is left to school. |
Feedback How fast do mistakes get caught? | ✓ Instant Every answer is checked on the spot, with hints that guide instead of giving it away. | — Next session Packets come back corrected at the next visit, then get redone. |
Subjects What's covered — and what it costs | ✓ All of them, one plan Math, science, English, social studies, French — real Alberta curriculum in one membership. | — Math & reading Two programs, each enrolled — and paid for — separately. |
Mixing it up Interleaved practice | ✓ Mixed warmups Daily warmups blend subjects and topics, so kids learn to pick the right strategy — not just repeat one. | — One type at a time Twenty near-identical problems per sheet. Great for speed, weaker for transfer. |
Made personal Does it know your kid? | ✓ Their interests, their pace Examples reshape around what your child loves; practice targets their weakest concepts first. | — Same sheets for everyone The level is personal. The worksheet isn't. |
Drill & automaticity Credit where it's due | ◐ Focused practice Targeted practice on weak spots — honest answer: for raw arithmetic drill volume, Kumon still sets the bar. | ✓ The benchmark Sixty years of making math automatic through sheer disciplined repetition. |
Practice designed by memory research
Every part of a Delta session is a named, evidence-backed learning technique — not a worksheet philosophy from the 1950s.
A scheduler tracks every concept your child knows and brings it back at the moment review does the most good.
Low-stakes questions in every single lesson — because pulling knowledge out beats re-reading it in.
Kids teach concepts in their own words and get real feedback — the fastest way to find what's fuzzy.
Practice targets what's wobbly, one notch above comfort — never busywork on what's already easy.
