Common questions.

Will my child actually finish this workbook?
Each day is one page — 15 problems, 20 minutes, then done. The same structure every day means less convincing, less negotiation, and a finish line your child can see from Day 1. 80 days, 80 pages, one clear goal.
Is this just another math app?
The opposite. Your child solves on paper with a pencil — no phone in hand during the 20-minute session. The app is used only after, for under 2 minutes, to enter answers and see the score. EEG research shows handwriting activates motor, sensory, and cognitive regions simultaneously — forming neural connections that screen tapping cannot replicate.
Does the app cost extra?
No. Instant scoring, 20-minute timer, parent dashboard, topic heatmaps, and step-by-step explanations — all included free with every workbook. One-time purchase. No subscription, ever.
How is this different from IXL or Khan Academy?
IXL is screen-heavy and costs $79–$159/year. Khan is 100% screen. 15Q20M is a paper workbook with instant digital scoring. No punishing score drops, no endless drills — just a clear daily routine that ends with a real score.
Is this a full curriculum?
No — and that’s by design. 15Q20M builds fluency on concepts your child has already learned at school. When your child gets an answer wrong, the app shows a step-by-step explanation. You never need to teach.
I can’t help with Common Core math. Will this work?
You don’t need to teach anything. Your child solves independently on paper, the app grades instantly, and wrong answers get step-by-step explanations. You just check the dashboard.
