Why MathTimer looks the way it does

Short reads about speed, color and the heatmap — with live demos from the app.

Why speed matters in math

Automaticity with number facts frees working memory for the part that's actually hard — problem solving.

How we map 'best time per fact' to color — and why that leads directly to the next thing to practice.

Splitting numbers into 10 + 5 + remainder makes addition and subtraction visible — and surprisingly fast.

Consistent color coding for each digit makes facts easier to recognize, remember and talk about.
