This is a set of 12 task cards on finding the perimeter of shapes! This file includes 12 task cards, student recording sheet, answer key, AND separate images for Plickers! Just upload the image as your question, choose the answer and you have a fun interactive game with you class. I also included all the full page images as a PDF file. This works well for a google classroom assignment! Just upload the PDF and have the students respond on the recording sheet or in their Math Journal! That means no printing for you!
