A newly trained teacher named Mary went to teach at a Navajo Indian reservation. Every day, she would ask five of the young Navajo students to __1__ the chalkboard and complete a simple math problem from   2  homework.

What am I doing wrong? Could I have chosen five students who can’t do the  6 ? Mary would wonder. No,  7  couldn’t be that. Finally she   8  the students what was wrong. And in their answers, she learned a   9  lesson from her young   10  pupils about self-image and a(n)   11  of self-worth.

Once she understood, Mary changed the system   18  she could check each child’s math problem individually, but not at any child’s expense  19 his classmates. They all wanted to learn,  20  not at someone else’s expense.
