CleverBlocks is a coding learning tool that turns commands from familiar block-type software such as Scratch and Blockly into tangible blocks. Kids who are not familiar with coding can easily attach and detach commands with magnets as if assembling real blocks, and naturally learn computational thinking skills and basic algorithms such as sequence and repetition. It is screen-free and can be operated in any environment without internet. A variety of add-on kits allow it to be used with many different roots.
