pat hole punch

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
If you understand the line of symmetry method, I don't think you need to spend time punching holes with real paper. You've already got enough to do in a day!🙂
 
no...practice using the video above and within a month or so of 15 min daily practice, you will be able to do it in your head!!
 
Might be helpful in the beginning if there is a problem you just can't understand with the line of symmetry method. Sometimes it just helps to see a physical copy of what you're answering to make everything click. Definitely don't do it for every problem, it's more of a last resort to understand a problem if you're not getting it.
