Program with WeDo 2.0
When students want to bring their models to life, they will drag and drop blocks 
onto the Programming Canvas.  As they do this, your students will be creating 
program strings. They can create multiple program strings on the canvas, but each 
of the strings will need to begin with a Start Block.
Here are some important terms to know: 
1.   Start  Block   
A Start Block is required in order to start a program string in WeDo 2.0.  
“Execute” means to start a series of actions until they are completed.
2.   Programming  Block   
Programming blocks are used in WeDo 2.0 software to build a program string. 
These blocks with symbols are used instead of text-based code.
3.   Program  String   
A program string is a sequence of programming blocks. 
The last block of the program string marks the end of the program.
