These are 10 CGI problems I wrote. The pace loosely follows the CGP textbook (chapter 3,) but these are stand-alone problems. Each problem has 3 different number sets so you can differentiate, as well as an extension problem for added challenge. The skills they encompass are: problem solving, percents and decimals, percents of numbers, percent increase and decrease and simple interest. These are ready to print, or you can change the names to your students' names to increase engagement.
