Software-based extensions were added in Scratch 3.0, such as text-to-speech voices, along with some new hardware-based extensions like the micro:bit. The extensions are listed ...
A simple custom block in the Snap! visual programming language, which is based on Scratch, calculating the sum of all numbers with values between a and b. In computing, a visual programming language (visual programming system, VPL, or, VPS), also known as diagrammatic programming, [1] [2] graphical programming or block coding, is a programming language that lets users create programs by ...
Snap!'s blocks are divided into eight groups: Motion, Looks, Sound, Pen, Control, Sensing, Operators, and Variables.

Blockly is used in several notable projects, including: MIT's Scratch, visual programming environment for education [6] MIT's App Inventor, to create applications for Android. [7] MIT's CoCo, visual collaborative programming website for education. Code.org, to teach introductory programing to millions of students in their Hour of Code program [8]
Scratch is a block-based educational language. The text of the blocks is translated into many languages, and users can select different translations. Unicode characters are supported in variable and list names. (Scratch lists are not stored inside variables the way arrays or lists are handled in most languages.
Sense is an educational programming environment created by The Open University (OU) in the United Kingdom. [3] [4] It uses a drag-and-drop programming environment designed to teach students the fundamentals of computer programming, using different shape and colour "blocks" selected from a palette of available commands, meaning that the student needs no prior experience of programming nor need ...
