Reflection

Two things I did well during this project were time management and communication. I practiced time management skills well during this project because we had to create our own schedule to get everything done. I managed my time well and I was able to get everything done on time. I worked on communication by communicating with teachers. During this project I would get stuck on a part and would have to reach out to the teachers for help.

Two things I need to work on are reviewing my work and getting right to work when I need to. I need to start reviewing my work more thoroughly because when I started to run my art show, there were many mistakes. I need to start reviewing it better so their are zero mistakes. The next thing I need to work on is getting right to work in the morning. I need to stop wasting time and get my work done early.
