I found a few great Valentine's Day Printables at Family Education that I thought would be awesome to do with your kids! (You do have to register...use an email, to view).
This activity book has word searches, V-day cards and crafts to do with the kids.
How to make a Love Bug (that's what I call my kids)
And of course some educational ones like Matching Hearts!
And don't forget to check out Family Education for more fun and educational arts and crafts. Tomorrow I'm going to post some fun Valentine's Day activities to do that I've found on Pinterest so stay tuned!
