Today I’m sharing some of the top building sets for boys and girls, ages of 7 and up. With movie favorites like Jurassic World and Transformers in mind, the K’NEX Beasts Alive building sets are in demand. Build dragons, dinosaurs, and more with the fun sets that come alive when the included motor is switched on!
I’m a K’NEX Ambassador. Product was provided for review and giveaway. All opinions are my own.
Building Sets for Boys
Use the 350+ classic K’NEX parts to build X-Flame, a ferocious dragon or 2 additional building ideas. Then switch on the motor to see him come alive.
This set contains over 250 pieces, including a battery-powered motor. Build the model, switch it on and watch it stomp to life! There are 2 model instructions included with this set.
Build a shocking K’NEX coaster classic with this 850+ piece set! Check out our full review of the Thunderbolt Strike Roller Coaster.
Building Sets for Girls
STEM learning products are flying off store shelves! It’s the latest in learning and geared towards both boys and girls. Check out these amazing Mighty Makers building sets for girls. Some of the top-rated sets are listed below like building a Ferris Wheel and Home. K’NEX also has a fantastic Education line with cool building sets like replicating DNA, building an amusement park, aeronautics, and much more!
Build your own amusement park with a ferris wheel, a pirate ship ride, and a boardwalk game. This 320+ piece set includes 1 figure and her precious bear.
Build your dream house from the ground up with best friends, Brianna and Sophia, in the Home Designer™ Building Set. This set includes over 430 pieces, including fun accessories to decorate the home.
The K’NEX DNA, Replication, and Transcription set is designed to aid in teaching the structure and function of the nucleic acid molecules that make up DNA. This set includes 521 K’NEX parts – enough to build 19 DNA and mRNA models, up to two at a time! It makes a great gift idea for teachers too!
