The Lego Group created LEGOs in the 1940s, but they are still very popular today among children, adults, and collectors. The Lego Group has released thousands of LEGO sets that are themed from basic sets to town and city sets, space themes, robots, pirates, vikings, castles, dinosaurs, scuba diving sets, wild west, the Arctic, mining, and airports.

The Lego Group has also released various licensed building sets such as Star Wars, Batman, SpongeBob SquarePants, Harry Potter, Bionicle, Indiana Jones, Toy Story, and Prince of Persia.

There are even bulk LEGO sets that you can purchase that do not have a theme, but just a wide assortment of lego pieces that you can put together and make your own creation.

The Lego Group has created sets that have moving parts, such as cars and tank, as well as motorized sets. There are a wide range of Lego accessories that vary from motors, gears, lights, sensors, and cameras that work with the basic LEGO blocks. There's even Lego Mindstorm sets that include advanced sensor technology for light and touch sensors, as well as rotation sensors and motors.

In most cases, the Lego building sets are for children at least 8 years old, but that doesn't mean that mom or dad can't sit down with younger children and build a cool building or car. You just want to be careful of younger children, especially those 3 years and younger that may try to swallow the small LEGO bricks and accessories.

The Star Wars sets are probably one of the more popular LEGO sets. There are many options to choose from ranging from battle scenes to space cruisers. You can stick with the Star Wars figures that come with the sets, but you can also purchase additional LEGO figurines. The Star Wars sets range from about $15 to $100+ per set, depending on how many pieces the set includes and how many accessories and figures you get.

Some of the more popular Star Wars Lego Sets include: Anakin's Fighter, Clone Battle Pack, The Battle Endor, Echo Base, Darth Vader's TIE Fighter, Hail-Fire Droid & Spider Droids, Assassin Droids Battle Pack, Corporate Allliance Tank Droid, Separatists Shuttle, Republic Gunship, Motorized Walking AT-AT, Hyena Droid Bomber, and the MagnaGuard Starfighter.

The Indiana Jones lego sets became popular with the release of the last few Indiana Jones movies. These sets range from $10 to $50+. They are a little less expensive than the Star Wars sets, but you'll find that most of the Indiana Jones Lego sets have fewer pieces and included accessories. This lego series features battles and chase scenes.

The more popular Indiana Jones Lego sets include: Fight on the Flying Wing, Motorcycle Chase, Ambush in Cairo, Temple of Doom, Chauchilla Cemetery Battle, Venice Canal Chase, Shanghai Chase, The Lost Tomb, Fighter Plane Attack, Peril in Peru, and the Temple Escape.

The Batman lego sets are a little bit more expensive, as they are slightly more of a collector's item for Batman paraphernalia collectors as well as LEGO collectors. Most of these sets will range from about $100 to $300+ per set, although you can find them cheaper if you just look for the best seller.

Popular collector's Batman Lego sets include: the Batmobile: Two-Face's Escape, The Batwing: The Joker's Aerial Assault, The Batman Dragster: Catwoman Pursuit, The Batwing: The Joker's Aerial Assault, Batboat - Hunt for Killer Croc, The Batcopter. The Chase for Scarecrow, Arkham Asylum, The Batcave: The Penguin and Mr. Freeze's Invasion, The Batcycle: Harley Quinn's Hammer Truck, The Tumbler: Joker's Ice Cream Surprise, Robin's Scuba Jet: Attack of the Penguin, and Batman's Buggy: Escape of Mr. Freeze.

The city lego series is a basic series that you can purchase. They include places such as the police station, the fire station, the city corner, and a construction site, as well as normal city things such as fire trucks, dump trucks, garbage truck, front end loader, Coast Guard patrol boat and tower, police helicopter, and a passenger plane.

By putting together multiple sets from the Lego City series, you and your child can come up with a rather large city that can and will definitely keep your child's imagination going.

Legos have been around for many, many years and with the proper tools and help, they are a great building toy that can keep your child's creativity going.

You can purchase the sets in your child's variety theme, and if you feel like your child needs a little assistance to complete the box set, it's a great bonding experience.

Just remember to keep the lego bricks away from young children and pets, as they can become a choking hazard for those who just don't know any better. It's also a good idea that you consider getting ziplocks or small containers to keep the pieces in the set separated, in case you can't finish the full Harry Potter classroom in one sitting. It would just be a a pain in the rear end if you had to go back through and separate the pieces; you'd be one step ahead of yourself the next time you and your child sat down to create a Pirates Loot Island.

Your child will remember sitting down with you putting together a Lego set. So just keep in mind that although the simple $20 set of lego bricks that make a SpongeBob Bikini Bottom adventure may seem silly to you, your child will remember it when he's older.
