"Kate, you will study math with us?”
I came here. I am sitting. I can barely follow them, because Zosia from middle school joined the two sixth-graders, and in a few minutes the pages were filled with all possible types of triangles and quadrilaterals, and around them were the same figures cut out of checkered paper. And I just sit and ask questions - not for that, to test their knowledge, just to get it.
These are the situations, where it's great to be unnecessary. 🙂
