Playing games with your pre-k and early elementary age kiddos is really important. They get to practice all sorts of things-- social skills, problem solving, fine motor development, early reading skills, etc. etc. If you tell your kiddos that these are educational, they'll balk. 'Cause who wants to spend an afternoon practicing skills? And if you try to rope an older sibling into it? Totally impossible.
Good thing all of these games are fun. They're sneakily educational. You won't feel like you're being tortured when you play them. And older siblings will want to join in, too!
