? On Monday, the homework was collected. Most children have finished their homework carefully, but they lack imagination and innovative consciousness as a whole. Looking at these works I handed in, I was a little disappointed. Maybe I ask too much, so I comfort myself that there is a gap between ideal and reality. Under such psychological suggestion, I quietly finished reading a piece of work again, but the more I read it, the cuter it became. Although these works are still immature and incomplete, each painting is enough to show their intention and ingenuity. Some of these works are vivid, some are exquisite, some are gorgeous, and some are very illustrated ... Their meticulous learning attitude moved me.

I shouldn't complain, but I should make good use of this opportunity to carefully analyze each work for them and put forward suggestions on how to improve it, at least give them a direction to think! If they all know, what else can I teach? Looking at the problem from another angle, the problem is not a problem. My friends and I carefully selected excellent works and printed them out as gifts for children on June 1. I think this should be the most memorable gift.
