    What we are practicing

    Tens and ones, joining and taking away within 100, and short stories with a missing amount. A ten is always equal to ten ones.

    Try it away from the screen

    Use counters, beans, or a drawing. Group ten small objects together. Ask: “What changed in the grouping? What amount stayed equal?”

    Let the child explain or show a method. Follow the teacher’s directions when this supports schoolwork. Adult help is optional.

    What the record means

    Finishing practice is different from showing independent understanding later with new numbers. This app has not been tested for learning effects or classroom alignment.

    Help, tools, examples and first responses are separate facts. Input mistakes are not counted as mathematical responses. Repeated tasks remain repeats.

    Privacy and saves

    No names, accounts, server requests or analytics are collected. Only an explicit save keeps practice in this browser. Language and reading choices are separate preferences.

    Saved records have limits: 20 earlier visits per task, 200 accepted actions per tool, 1000 checks per visit, 256 characters per answer, and 256 KiB total. A record above a limit is rejected whole; play continues.
