This CGI Joining Problem Bundle has 30 different problems for Join Result Unknown, Join Change Unknown, and Join Start Unknown! This package bundles my three different joining packages, but at a discounted price! I have made the bundle editable so that once you download it, you can change fonts, names of students, etc. to make it more meaningful for your class.
For each problem, I have included a teaching slide to display to your class (if you so choose) which also has the standards listed for K-2, a slide that can be used for students to record their work, and a slide that has multiple copies of the problem so that students can glue the problem into a math journal (again, if you so choose). Each story problem is presented with blank spaces and four number sets underneath. Students can plug in each number set into the blanks (they get increasingly more challenging), or you can choose which number sets students use. You can even differentiate which groups get which number set based on your students’ needs! I have also included other resources, such as a CGI rubric and a chart on the CGI problem types. I hope that you find this CGI Bundle useful for your instruction and beneficial for your students!
