Consumer Critique: Meigo Magnetic Blocks

I've seen magnetic building blocks before but never tried them out, so I was happy to get a chance to try out MEIGO Magnetic Blocks.

I'm a math teacher, so I can always see the STEM applications of toys. Not only do these have the obvious building aspect, but they are also useful to show the relationship between surface area and a three-dimensional solid (at least ones based on squares or rectangles and triangles). Each side has a different color, and the magnets are pretty strong so creations hold fairly well. The small magnets can be very dangerous if swallowed, but it would take a pretty destructive child to get the magnets out.

The description says perfect for preschool, but honestly, my fifth grader enjoyed them as well. The booklet comes with several pages of flag diagrams, sort of like simple mosaics, and then several pages of turning flat diagrams into 3D creations. It might be a little challenging for younger kids to turn the flat into the 3D on their own, but building in 3D is pretty easy.
