孩子回答 10～20 題選擇題，從數數、湊十、20 以內加減、二位數加減、九九乘法、除法、分數到多位數乘法，依孩子選的年級從中間開始：答對就往難一點的走，答錯就往簡單一點的走，找到「已經會」和「還要練」的交界就結束，大約 3 分鐘。每一關最多出 3 題，答錯或按「不知道」都沒關係，不會顯示分數。
結果會推薦從哪款遊戲開始，也會成為首頁「今天練什麼」的新挑戰；有適性難度的遊戲（湊十小火車、泡泡魚、螞蟻搬豆子、甜點盒拆拆樂、接力賽計分板）還沒玩過的話，會照探測結果先設定難度。這只是幫孩子找起點的小測驗，不是正式評量，結果只存在這台裝置。家長可以在家長專區看結果，隨時可以再測一次。
Your child answers 10 to 20 multiple-choice questions, from counting and pairs to 10, through adding and subtracting, times tables and division, to fractions and long multiplication. It starts in the middle for the chosen grade, moves up after right answers and down after wrong ones, and stops at the line between “already knows” and “still practising”. Each step asks at most 3 questions; wrong answers and “I don’t know” are fine, and no score is shown.
The result suggests which games to start with and becomes the “new challenge” on the home page. Adaptive games your child has not played yet start at a level based on the check. This is a quick way to find a starting point, not a formal test, and the result stays on this device. See it on the parent page and take the check again any time.
