We created our own mail center in our schoolroom and play room because my kids love getting the mail. They love to send letters to friends, teachers, and grandparents. They love to send and receive mail. I made some monster post cards to help us practice writing, addressing, and sending mail. Of course, these aren’t post cards for the US Postal Service: they are for our own homemade mail box!Practice letter writing with these monster postcard templates. Addressing a letter, parts of a letter, and more is included with the download.

Making a Cardboard Mail Box


To make our own indoor mailbox, I found a rectangle of cardboard. It was flexible but strong. It had a flap of cardboard in the front that reminded me of a mailbox flap.

It took some simple bending and some painters’ tape to move it in the the correct shape. I used an Exacto knife (aff link) to cut it into the proper shape and cut out a back for our mailbox.

My son loved to paint it with me.


Writing Letters on Monster Postcards

To add to our fun, I decided to make some postcard templates. I made two different options, one for my toddler and the other for my second grader.

Our dry-erase crayons (aff link) are perfect for this! Note that the crayons are much less messy than the markers would have been. They wipe off very easily, and Strawberry can write a new letter.

Then, for my second grader, I intended this to be a handwriting practice center as well as a fun play place! I made a blank template with primary-grade lines. We talked about the parts of a letter. Obviously, this is a much casual letter than some may be, but I still expect him to have the basic parts of it!

He was very eager to write me a letter. While usually I have to cajole him to do his handwriting or copywork practice, this time he was excited.

“Don’t look!” he kept telling me.

The kids played for an hour with our mail center. I am excited that they are getting writing (or in Strawberry’s case, pre-writing) practice all the while having some imaginative fun!
