This zipped folder contains a student notes page, a homework page, and a short quiz over nonstandard operations for algebra students, as well as a teacher key for each page. What I mean by nonstandard operations is problems like this one:
If a @ b = 2a + 4ab, then what is the value of 3 @ -7?
The notes page explains the concept and gives several examples to work out with students. The homework pages gives them an opportunity to practice this skill, and the quiz allows teachers to briefly assess students' understanding of the topic.
