Read a book 1
There's not a ton of children's books out there about Dia de Muertos, but this one is certainly a favorite. A cute little story told from the unexpected point of a view of those who are celebrated: the dead.
Make an altar 2
So many ways to make an altar for Day of the Dead and you can make them as elaborate or as simple as you want. But I truly like these mini altars made of shoeboxes and/or matchboxes because I think they're perfect for little kids. Get the step-by-step instructions on SpanglishBaby.com.
Make a craft 3
Making papel picado is a great craft you can work on with your kids. Use it to decorate your altar or your house and have lots of fun while you're doing it. If your kids are anything like mine, they'll love being told to cut away!
