    There’s a program for middle schools called Treps that teaches kids about business and product development. The students are given the task to learn to _______  products on their own, and at the end of the program the school gym is _______  up like a trade show where all the kids  get to  sell  the products. They each  get a_______, make signs  and dress up a little. The school gym is open to the public and_______ a crowd.

Some of the kids there  _______have a crowd at their stand, because the products made by themselves are unique and interesting.  But there are some  other kids, with _________that aren’t very good, just don’t stand out, aren’t getting attention. At first, they stand there with a _______ face but later you can  see the  _______in  their eyes because everyone walks by  the stands uninterested. I always think it  _______to visit the stands of those kids, buy something, and ________ them for how hard they must have worked on it. Just the confirmation that someone    likes what they make  and notices their effort can________  them. I usually bring  $100 to this  event merely for this __________. As the night goes on, ________  they still haven’t sold much, I will  send my daughter over there to buy something from them.

The other day, as an education expert, I was________ with some parents about this. They  asked me why I encouraged the kids who made terrible products, saying “________ confirmation means they won’t learn anything”. I told them, “These kids know their products aren’t a________ ,  but that doesn’t mean they should________. It takes courage to________ there and try to sell their products. If nobody buys anything, or nobody________ their effort, they will probably quit next time.” Hearing these, all the parents agreed.

A little encouragement can go a long way and sometimes a small lie can be a big________ in the right direction.
