Love your monster themed materials! I am using them to go along with the monster theme from the Class Dojo behavior management app on Google. Check it out if you're not familiar with it. I just started using it this year and my students and I love it.
I love this idea to help practice spelling words along with math skills. Area and perimeter are hit very hard in third grade. However, when I downloaded it on my school mac computer it did not come in very clear and the letters are overlapping. Is there any chance you could email me the document to email@example.com?
Thanks so much!

Make sure that you save it to your computer and then open that file. Do not try to open it from the download. If that still does not work, email me at firstname.lastname@example.org and I will send you another copy.
Have a great day!
