## Reflection: Introducing the Minus Sign - Section 1: Problem of the Day

I chose a student who does not usually volunteer to do Problem of the Day for today's lesson.  He loves to pop the balloons (we have used these in several reading games), but his counting skills are weak.  I called him up and reread the problem.  I asked how many balloons her brother popped as I pointed to the number and he said 6.  I asked if his friends could count with him as he popped 6 balloons.  He said, "Sure!"  All of the students counted the balloons as he popped them and then a friend came up and wrote the answer.  He then read the number that his friend wrote.  The student got a chance to practice identifying numbers while he was in the front of the room, and he gained a great deal of confidence and was happy to participate which is a great step forward for this student.
