I have been cutting apart all the boxes I can find in my house. I've been getting super excited when I finish whatever is in a box so I can cut the letters out. Nerd, I know! My roommate saw the container sitting on the counter the other day and thought I was sending out a ransom note. LOL
What you will need are empty boxes, such as cereal boxes. Cut out the letters and put them in a storage container. That is it!
I've asked my own parents to save their boxes, too. Another idea is to ask your students' parents to send empty food boxes to school.
If you would like to see the original idea from Pinterest, here it is.
I just thought I would forward on this neat little piece if you haven't seen it on Pinterest yourself.
