About FDP Equivalence Quiz

FDP Equivalence Quiz drops students onto the floor of a global finance exchange, where prices flash between fractions, decimals, and percentages. Converting fluently between the three forms is the core skill of the game and a cornerstone of the secondary number curriculum, reinforced here with fast, clear questions. It is built for ages 11 to 12 (grade 6 and grade 7) with clear instructions, large touch targets, and progressive difficulty, so students can work independently or alongside a parent. Correct answers bring encouraging feedback and a small celebration, while mistakes are never punished and simply invite another try, which keeps confidence high. The challenge grows step by step so it always matches the learner, supporting steady progress across the lower-secondary curriculum used in the US, UK, Canada, and Australia. 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 Logic Masters worksheets for offline practice of the same skills.

A hand for grown-ups

Before you start
Something you can cut or fold helps enormously — paper, fruit, a sandwich. A half you can see beats a half you are told about.
While they work
Keep coming back to "equal parts". A shape split into unequal bits is the classic fractions trap.
Afterwards
Fold a piece of paper into halves, then quarters, together. Watching the pieces double is a lightbulb moment for many children.
Watch out for
Thinking a bigger bottom number means a bigger fraction (that 1/8 > 1/4). Cutting a real thing into 8 vs 4 pieces settles it fast.
Away from the screen
Cut food into equal parts at mealtimes. Fold paper. Talk about "half" and "quarter" of everyday things.

How to play

    Answer options are shown as large buttons. Tap an answer, or press keys 1–4 on the keyboard. 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 6 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.
