About Addition Bond Flip

Addition Bond Flip is a treasure quest through ancient ruins. Children flip cards to find two numbers that add up to 20, building number bonds and quick addition. It is built for ages 5 to 7 with clear instructions, large touch targets, and gentle pacing, so children can play independently or alongside a parent. Correct answers bring encouraging sounds and a small celebration, while mistakes are never punished and simply invite another try, which keeps confidence high. Difficulty grows step by step so the challenge always matches the child, supporting steady, progressive learning across the grade 1 and grade 2 curriculum. The game runs in any modern browser with no app to install, no sign-up, and no advertising shown to children. Progress is saved only on the device and appears in the Parent Dashboard, so families can follow growth without any data leaving the browser. It pairs well with our matching Little Learners worksheets for offline practice of the same skills.

A hand for grown-ups

Before you start
Have something countable nearby. Being able to check "3 and 2 really is 5" by counting builds trust in the maths.
While they work
If a sum is hard, suggest counting on from the bigger number rather than counting both from one. It is a real strategy, not a crutch.
Afterwards
Try one together out loud, talking through how you worked it out. Hearing an adult think aloud is genuinely useful.
Watch out for
Counting both numbers from one every time. Nudge gently towards "start at the bigger one and count on".
Away from the screen
Add up small shopping items, or dots on two dice. Board games with dice are addition practice in disguise.

How to play

  1. A question appears on screen

    A maths question is shown in large text at the centre of the play area. A timer bar begins counting down from 60 seconds.

  2. Choose the correct answer

    Answer options are shown as large buttons. Tap or click the correct option. Any input method works — touch, mouse or keyboard.

  3. Build your streak

    Each consecutive correct answer increases your streak. A longer streak lights up the flame icon and adds a bonus multiplier to the XP you earn for the level.

  4. Finish the level

    Each level has 4 questions. Complete them to earn the full level reward (+10 XP, plus up to +10 XP for a perfect run). Progress is saved locally and shown on the Parent Dashboard.
