Type in the words once. Your child presses play, hears each one in Mandarin as many times as they need, and writes it on paper: squares for 汉字, a ruled line for 拼音, so they know which is wanted before the test, not during it.
Two minutes for you, then it is theirs.
Copy the 我会写 and 我会认 words straight off the worksheet. The pinyin fills itself in.
Each item is read in Mandarin. 再听一次 repeats it, as often as they like. Nobody has to sit with them.
The answers come up in 楷体 with the pinyin, they tick or cross, then practise just the wrong ones again.
One per line. Commas, 、 and spaces split too, so a line copied off the worksheet usually just works.
Heard, then written as characters, one square per character.
Heard, then written as hanyu pinyin, one ruled blank per syllable.
The sheet prints with the right blank for every item, so the shape of the answer is settled before test day.
Keyboard: space repeat · ← → move · enter play or pause
Compare what is on the paper with the answer. Be honest. The point is to find the ones to practise again.
