Practice: Adding to 20 without crossing ten
All the questions sit under each other, like on paper. Where you can tap (signs, yes/no, shapes), tap — do not hunt for a keyboard. Otherwise write the answer and press the tick, or Check all at the bottom. Green = right. Red = not yet. 开始 with ten. When it goes well, add more.
