← Write One Together · Lesson 3 of 3
Solve it, then swap
A finished problem gets two tests. Can its author solve it? And can someone else solve it from the words alone? The second test is the stricter one, and it is where the arithmetic gets checked for free.
So write one each, about different things you love, and swap. Solve each other’s problems out loud. If one cannot be solved, the author fixes it; nobody is marked.
Which of these problems has exactly enough information to answer?
A lesson is kept once you've answered the question and written at least 8 words. Nobody grades it; it stays on this device.
