Lego relay
Break the kids into four equal teams, and have each team sit in a corner of the room. Place your large box of Legos (which you used in the previous activity!) in the center of the room. (If you don’t have a big enough box, place a hula hoop on the ground and dump the bricks out in the center of the hoop.) Number each team member, so that one child is “1,” the next is “2,” and so on. Designate a game leader (it could be the birthday child, or an adult) to yell out instructions and keep track of who has already been called.
Once you’re set, have the leader yell out a number (which corresponds to a team member) and then a type of Lego. For example, they could yell out, “Number ones, yellow Legos with six studs!” The “1” from each team then runs to the box full of Legos, and searches for a yellow six-studded brick. (“Stud” is the official term for the bumps on Legos -- make sure the kids know that ahead of time, so they don’t look at you like you’re from Mars when you call them that!) Once the player has found the right brick, they run back to their team’s corner and sit down. The first team to get their player back and seated wins a point. Play continues in this way, although after the first Lego, all other Legos must be connected to the previous Legos before the player can sit down and claim a point! Keep playing for as long as you like.
Lego surprise
This game takes a bit of preparation ahead of time. Using our treat balloon technique, place small, square Legos (either the 2 or 4-stud size) into primary-colored balloons, and fill with air. Make sure you use only a limited range of colors for your Legos, like only red, yellow, and blue. Also be sure to have a good mix of colors, because the different colors will make a difference later in the game! Place all the balloons in a big box or bag that is accessible to everyone. Divide your group into teams and line them up on one side of the room, one behind the other. Place a chair for each team on the opposite side of the room. On “Go!” have the first person race over to the box or bag, grab a balloon, run to their chair, and sit on the balloon until they pop it. Once it pops, they must retrieve their Lego piece and race back to their team to tag the next player in line. Play continues until all the balloons are gone. Once play is over, have the teams count up their Legos and award points for the different colors they have. For example, you could say that they get 1 point for every red brick, 2 for every yellow, and 5 for every blue. Add up all the points to determine your winner.
Lego Carnival
Another great idea is the Lego Carnival! Turn standard carnival games into a Lego-fied ones by building pieces out of Legos. Make sure that you do this in a location where nothing can get broken!
Bowling for Legos
Make 3 “pins” out of Legos. Line them up one next to the other, with space in between them. Use rolled up socks as the ball. Each person gets two rolls to see if they can knock down all three pins.
Lego shoot-out
Make Lego targets and place them on a table; use Nerf guns, rolled-up socks, or Frisbees to try and knock the targets off the table.
Lego toss
Place a series of buckets or bowls in a line (front to back, headed away from the player). Stand back about 10 feet and try to toss the Legos into each of the bowls. Give players the same number of Legos as there are bowls. The object is to try and get one in each of the bowls, although not necessarily in order!
Hockey shoot out
Make an archway out of Legos. Make a few “pucks” out of bricks (or just use small base plates). Stand a few feet back and try to slide the puck through the archway.
