• WELL DESIGNED PLANKS: KEVA pine planks are precision cut blocks that stack and stack with surprising stability.
  • NO HASSLE: Narrow towers can reach the ceiling. Cantilevers can balance beyond belief. No glue or connectors are used, just gravity and imagination.
  • TOYS THAT TEACH: Building brain power plank by plank. Playing with planks gives builders first-hand experience with balance, leverage, geometry and principles of physics.
  • INTERCHANGEABLE: These planks are the same size and shape of other Kapla or KEVA planks and thus can be used interchangeably with those systems to construct elaborate and expansive structures.
  • INCLUDES: 200 pine planks and a 24 page full-color idea booklet with build-out instructions.

I gave this to my 7-1/2 year old son for Christmas, three weeks ago, and he and I have played with it every single day since then. So far, we've only built bridges, but what a variety -- we've created cantilever, beam, arch (sort of), double-decker, and pontoon bridges. We've experimented with variations in total length, length of a single span (the part of the bridge between the support piers), and vertical clearance (the height from the floor to the bottom of the span). Each time, when we're done, we subject our spans to the loading test (placing a medium-weight stuffed animal on it) to see how it fares. And if that doesn't destroy them . . . well, dropping "bombs" from up high will eventually do the trick! (The blocks make a great "crashing" sound on the hard-wood floor where we do our construction.) All the while that we're having fun, my son is also learning about the principles of bridge-building and other aspects of architecture and design. Plus, he gains the satisfaction of being able to independently create something, construct it, and see it through to a successful completion. And to top it off, it's wonderful for the two of us to share in all the fun together. This is a great toy: no batteries, no complicated instructions, no searching for just the right pieces, no mindless staring at a screen, no messy glue or paint . . . just loads of good old-fashioned fun.

These are the best blocks. I used them in a girls STEM camp of middle school girls. The girls loved building with them. Anyone who might be interested in building/engineering would love these.

My kid loves building with just about anything and everything. Legos and Magnets were getting tiresome for ME so I decided to get this and mix things up a bit. He loves the challenge of the Keva planks not interlocking or being magnetized. Glad I got them, it's a refreshing change.

We visited a science museum that had these planks. My seven year old granddaughter was fascinated designing a building. I bought the 400 plank construction set to have on hand when she visits. The booklet shows photos but no directions other than showing different ways the planks can be used for size and strongest support. I suppose that could be part of the fun and challenge in trying to figure out how to build the structures and encourage "engineer thinking". All the pieces are smooth and a good pine quality. They should last to be used by younger siblings. I expect this to be a winner and favorite.

These basic planks have entertained our kids since they received them at Christmas. They are smooth and come with the idea book and the black tote to keep them in. I thought these were expensive at first, but they have definitely been a toy that has been played with every single day since they got them. Would definitely purchase again! My only con is that.......They are made in China. I really wish they were made here in the USA.

We bought this for our son for Christmas this year...and are discovering that all of the family (ages 5 to 43) love it! Since Christmas there have been several times where we've all sat down together to build. Although we do a lot of things together as a family, this may be the first "toy" that we've all enjoyed equally as a family. It seems kind of crazy to spend so much money on simple planks, but they are so well constructed and can be stacked and manipulated easily, even by a 5 year old. These will be used for years to come, so are definitely worth the cost. I'm sure at some point we'll buy more!

I'm about to buy my 8 year old son his 4th box for Christmas. He is a plank building machine. These are the BEST THINGS EVER! We have never had a problem with a single pine plank-ever. The things my son comes up with blows my mind!!! He recreated the Washington Monument in our kitchen last year (3 boxes) which stood 7.5 feet tall!! I recommend this toy to every single person I know whose child loves building things, architecture, engineering or LEGOs. So refreshing to see a child using their brain (and not on a gaming system!!!)!! A must buy!!!! Worth the cost!

It is what it is. A big box of building 'planks' I was surprised at how many of us have now played with this thing. If the kids like legos, they'll most likely love these things. By the day after we got this thing, all the kids and I have tried our hands at building the biggest, tallest, coolest, weirdest, whatever, structure we can come up with. Lots of fun, and when done, can then play godzilla and destroy your structure and do it all over.

I debated forever over the maple and the pine blocks. I read the reviews over and over, moving one into my cart, only to remove it and add the other. I finally decided on the Pine…we're not made of money, and lets face it--it's a box of wooden blocks! Anyway, my son LOVES this kit! I was surprised to find the directions are really just a collection of completed projects with no steps. I was even more surprised that that didn't stop my son! He's a bid of a instruction die-hard, but he adapted quickly to looking at the photos and mimicking the layouts. Also, if you type in Keva Structures into YouTube, you'll find some other ideas. We will buy more of these sets. So glad I didn't drop all that $$$$ on maple blocks.

These are so simple, yet you can do amazing things with them. It’s so nice to have something my 13 and 11 year old can play with, and it involves no screens! Also, no plastic (except wrapped around the blocks which I wish would be eliminated-a simple band of paper could be used), just wood and a cardboard box.
