I don't know how it happened. Once we were united, a single people.  But the divide between us has started to grow. We are now two factions staring each other down through the hole in the schoolyard fence. On the outside chewing gum and wearing flip flops we have Still Loving the Summer.  Sitting at their desks with hands folded neatly in their laps are the Back in School bunch. Still Loving the Summer stays out past sundown, catching movies and concerts under the stars. Back in School is trying to learn a trade and wondering if Superhero Shakespeare counts for extra credit.

But there's hope. We can still find common ground. Everyone can agree on some things, like, no one likes jury duty, right?  And on a more positive note, everyone loves birthday cake. Right?  See, despite our differences, underneath we're really the same! We're one big happy family again, even if some of us can still sleep in.

Keep reading for some of our favorite picks for this weekend, whether you're back to school or not...

I remember when my son was first learning to add numbers. He was so proud of himself. His face lit up as he proclaimed proudly, "2 + 2 is 4!" But soon the equations and concepts became more complicated. He was forced to do daily flashcard drills and endless worksheets, and I saw his initial enthusiasm start to fade. That's when I decided to turn math time into playtime with fun and engaging board games.

While there are plenty of math apps he can play alone and hands-on activities at the Museum of Mathematics, board games help him learn new mathematical concepts or master old ones in a supportive and entertaining environment. Family game night is a great bonding experience, too, and it certainly doesn't feel like work. Here are six board games, all under $20 and aimed at a variety of ages, that my family and I often play together. They're so much fun your kids won't even realize they're doing math.

It's nearing the end of summer and half the city tends to empty out as beach goers head down to the Cape and Islands for last minute getaways.  If you are like me and choose staying local over fighting bridge traffic, you can still create your own little beach getaway right here at home.  Castle Island is a 22-acre recreation site located at the tip of the Harbor in South Boston, just 10 minutes away from the Central Artery.   Below are ten things to do there (and ten tips!) to help plan your trip to one of Boston's most popular destinations for tourists and residents alike.
