SO many great indoor games, building activities, and science experiments by a mom of boys. Lots of good learning stuff too. Perfect for these HOT summer days we have!

Play this every Christmas, but using gloves, makes it way funnier. Have everyone who is playing get in a big circle, one player gets the tape ball and the player in front of them a pair of dice. The player with the ball removes tape as fast as they can and anything they dislodge is theirs to keep. The player with the dice is trying to roll doubles as quickly as they can so they get a turn. As soon as they get doubles they pass the dice to the person next to them and then they get the tape ball.
Use for rewards? The numbers are magnetic. Kids pick one and get that reward. It could even be a certificate for no homework. :)
