This is an excellent way to introduce young children to addition. The best part of this place mat is that in the back it contains addition equations on the back so kids can practice their addition skills. Made with a custom non-glare laminate on the front and a write-on/wipe-off laminate on the back so you can fill in the answers with a dry erase marker or washable crayon and wipe off with a wet cloth! A great way to keep your dinner table clean and help children learn important mathematical skills.
