    Standing at three and a half feet tall, this motorized K'Nex contraption is as close to the real thing as you can get. Once everything is assembled, the cart will run without stopping, as the motorized portion lifts it back to the top to start over again. With loops, tight turns, and steep drops, this kit will be fun to build and rebuild. The usual K'Nex simplicity makes construction easy. ~ Mark

    Rainbow Price: $14.50
    I've always loved building sets, and these are no exception. Each of these kits (three assorted styles) contains 156-163 pieces, each of which includes a battery-powered motor (2 AA batteries required, not included), so parts of the finished build will move. The Robo Sting has wings that flap, the Robo Smash has arms that move up and down, and the Robo Strike has a scorpion-like tail that moves back and forward. What's extra cool about this set is that the pieces from all three kits combine to make the Robo Combo. Instructions for this build are available on the K'Nex website, and the link and download code is available on the back of the instruction book included with each kit. Time to get building! – Laura

    If you're a mini-golf fanatic, perhaps the next step is to make your own course. This crazy set from K'Nex includes all the pieces (and instruction) you need to assemble a 9-hole mini golf course, complete with a Ferris wheel, jumps, ramps, spirals, trap doors, loop-de-loops, and more! The course can be used indoors or outdoors – but you may want to bring it inside before it rains, due to the cardstock flags. Two putters and four golf balls are included so you can play with your buddies. Putting together this set does require a considerable time investment. Once completed, however, the set can be left intact, provided that you have a place to store it. Definitely not just a thrown-together putt-putt kit – this set will challenge kids and adults alike with its varied obstacles!

Video instruction, programming software, user guide, and additional PDF files are available at the publisher’s website. This may look like a toy, but students will learn how to build, program, and control their project, and maybe even come up with some of their own creations. ~ Donna
