This file is a digital interactive version of an activity that I posted on TpT for the spiral interactive notebook. You can find the original paper version at https://www.teacherspayteachers.com/Product/Classify-Triangles-Cut-Out-Activity-731031. With the digital interactive version, your students won’t need glue or tape and they will always have their “notebooks” with them as long as they have access to technology and wi-fi! No more wasted money on excessive supplies or wasted time waiting for students to cut and paste. Another advantage is that students can redo the activity when practicing for assessments. In the paper version, it would be permanently glued down.
