IO Blocks by Guide CraftWe were fortunate enough to be selected to review these blocks via @Tryazon! These blocks are great STEM toys for children! My 3 year old loved playing with them just as much as we adults did!

We received the 500 piece set that included the tote of blocks and 20 double sided creativity cards with examples of what you can build and they even list what blocks you would need to create the design.

These blocks come with a really cool augmented reality app (free on iTunes and google play) that can be used with the tracker card to help you to see how each design is made! We found it easier if one person held the phone over the card and another person built the project, otherwise the app would stop if you removed it from the tracker card and you would have to start all over.

We were able to build so many cool projects! From animals to robots!
The plastic is very smooth and doesn't have sharp corners like usual blocks and bonus, they don't hurt like Legos if you step on one!

I really enjoyed watching my 3 year old use these blocks to exercise her fine motor skills and learning spatial concepts!
These blocks are available from a 59 piece travel set up to a 1000 piece educational set! There's a set for everyone!
