Just as important is that Scratch graphical programming software allows children to learn from the simplest codes and master systematic programming knowledge. Meanwhile, the Lego series can be used to build various shapes and inject some basic physics and mechanical knowledge to children,thus greatly boosting their logical analysis ability, creative ability, hands-on ability and problem-solving ability.
