Reflection «Self assessment»
1 | 2 | 3 | 4 | 5 | 6 | 7* | 8** | 9** |
On the second row put:
, if you solved the problem individually;
, if the problem was solved with a hint;
, if you got detailed description
Analyze the table of self-assessment, note which problems were solved easily, when solving what problems arose, look for ways to solve them.
