I ran into a student that I used to teach that is currently a senior in high school. She said that she is taking honors pre-cal and not doing well at all. She actually stated that this was the worst teacher that she ever had! I tried to tell her to don’t give up and referred her to Mathway.com.
Mathway is a site that actually allows the user to enter problems and solves them! It also breaks down problems and explains how the answer is derived as a tutor would do for a fee I believe. Check it out. I highly recommend this site especially if students struggle and use it properly to check their answers, rather than to just get an answer w/o work! Teachers may use it as a resource too when they get a little deep in the water as well or have no textbook key!
