Today we worked again on graphing functions, but now they had to come up with their own inputs to find the outputs. They were given a page of six blank tables and graphs. Around the room were 15 different functions for which to choose–quadratic, linear (including 0 slope, which led to lots of conversation!) How can I check 25+ students’ work/tables/graphs when they all choose different functions!? Enter: desmos.com
This site and app allows you to explore graphs, evaluate equations, make tables, and more—all for free! As a class, we went through the key features (making tables, graphing functions) but then the students were on their own. They had to do their own tables and graphs and use desmos to check their work and compare their drawings.
