Program with WeDo 2.0
When students explore programming for the first time, they will probably line up as
many blocks as possible on the Programming Canvas. To carry out an idea they
have in mind, they will either arrange their blocks in a flow so that they are
executed one after the other, or executed simultaneously.
Here are two important terms to know:
1. Linear Sequence
A linear sequence is when blocks are placed one after the other in a linear
fashion. The LEGO
®
Education WeDo 2.0 software will then execute one action
after the other in the order in which the blocks have been placed.
2. Parallel Sequence
A parallel sequence should be used when students want to perform two or
more actions simultaneously. In this case, the actions should be placed on
different program strings and executed at the same time, using the various
techniques available in WeDo 2.0.
Suggestion
Tell your students to plan their programs in advance. This will help them when they
are deciding the order in which the program actions should take place. They could
use the Documentation tool to write the actions they wish to program, step-by-
step. They could also use a mind map of their own to decide whether they should
use a linear sequence or a parallel sequence.
