I like that you have to set the runs up just right to get them to work. Makes my children understand that engineering takes a lot of tries.

I introduced this kit in the classroom by setting the easy levels up with a couple students at a time. We did the hard level 6 run as a large group, and then I let them go. While I've had a few that continue to use the cards, they've also enjoyed setting up their own runs. My 5 year-olds are trying to use all the pieces and are very persistent in trying to get things to work the way they want. The younger 4 year-olds are more interested in seeing how fast or far they can get the balls to roll. The first graders have also enjoyed using it and have been asking for more pieces to make elaborate runs!

I got this for my 5 year old grandson and he loves it! Challenges him and keeps him interested for a long time. Great for keeping him thinking.

I teach second grade and my students loved setting these up. The cards are fairly easy to follow and the plastic is sturdy and colorful. Perfect for a center, and doesn't need too much explanation. Great for team building:)

Reminds me of rhe incredible machine computer game from when I was little. The kids/students in my life love it!

I got this for my 4 year old who loves marble runs and building. This was too difficult for his age. Everything has to be lined up exactly. The pieces would just fall down too easy and just not good for a 4 year old.

This was a fun kit and definitely well made. Everything was easy to understand and setup, however, I found it was not very challenging for my 7 year old. He was able to independently complete just about all the challenges without much trial and error. Definitely consider your child's abilities and maybe go up to the older kit if your kid is like mine.

I could easily see this set be a good introduction for children starting at the age of four, but still continue to be a challenge for children even in higher grades. It is fun over all. The quality is as expected

Well designed and fun!

Our 7 year old had a great time, and was able do all of the plan needing help only for the highest level. Our almost 4 was completely lost but had fun once big brother completed it so pre K might be young yet. Over all this was a hit. Great way to bring up some physics.

My son is 4 1/2 and likes the idea of this, but the concepts are too difficult fir his age. He likes to watch the ball and halo set it up but I do most of it. Wouldn't be appropriate for a preschool, pre k class. Maybe some kindergarteners could do it. The biggest complaint is that the quality isnt good for this price. The lightweight ball broke in half the first week we had it. I couldnt imagine this lasting in a classroom.

Sent this starter kit to my granddaughter. She played with it as soon as she got it and for the next two days (so far). Looks like a great learning took
