Any St. Patrick's Day celebration is sure to involve a little mischief, maybe some treats, and a whole lot of green. Mix it up this St. Paddy's Day and throw a little learning into the pot with a leprechaun matching game. This activity will help improve your child's memorization skills and he'll likely find the variations in how leprechauns are depicted very interesting. Remember that leprechauns are crafty characters, so matching them up might be difficult for your little one initially. But with a dash of perseverance, he'll pair them up in no time.
