Here is a great math activity for the holidays. This activity allows students to learn new concepts in a fun way. This is a great way to front load skills that may not be taught until later on in the year. I love teaching math through art because you get high engagement because 'Duh' it's so much better than doing another useless worksheet.
You may change the measurements to fit your need.
Look for the word document to download the directions to this great activity.
