At the end of every math class I teach, I give out little quizzes to check for understanding. They're only two questions long and cover only the information taught that day. I started this at the end of last year, and I love doing it because it gives me such a clear idea as to how well I taught and how well they absorbed the information!
Right now in second grade, we're covering graphs, and my little quiz for tomorrow is on reading line graphs. Now, I am for sure NOT going to hand-draw a line graph for their little quizzes. That's just cray cray.
Instead, I remembered this sweet website I found last year - NCES's Create a Graph! If you just input your data, it makes a lovely little graph just for you.
You can print it straight from the website or save it in a variety of formats - PDF, JPEG, PNG... whatever you want!
Your students could use this also instead of hand-drawing graphs. I had my own students use it last year when we studied natural resources. It was a bit on the complicated side for my class (there are a lot of steps to make a graph), but if you modeled it and had them use it on a regular basis, I think it could really come in handy!
