    For grown-ups

    A model, after the real thing

    Try the workbook's real test first. Then use a model to look again from a new side. Ask your child what the model shows well, and what it leaves out.

    • Not to scale.

      Sizes and distances are changed so everything fits on one page. Each model says so on screen.

    • Private and offline.

      Everything is drawn on this device. Nothing is uploaded, and no account is needed.

    • Calm motion.

      Turn on "Calm motion" in the menu, or your device's reduce-motion setting, and models change in steps instead of moving.

    • Keys and touch.

      Every action has a big button. Arrow keys turn the view, and + and − zoom.
