Blockly is a fun, graphical programming language designed to get kids interested in creating their own computer programs. Through simple text written to foster creativity and problem solving, students will learn the art of innovation. Large, colorful images show students how to complete activities. Additional tools, including a glossary and an index, help students learn new vocabulary and locate information.
I really like this for early childhood children and families Explains Blockly and has resources wonderful pictures and links for additional information
