This review is from: K'NEX Education - Elementary Math and Geometry (Toy)
My ten year old nephew had some other KNEX toys he wanted for Christmas so I ordered this to add on to them. Since he got it he has been building and learning at the same time. He hardly wants to stop playing with it. A good choice to expand on the math skills a fifth grader is learning in school.
