Coding WeDo 2.0

Download the free Lego WeDo 2.0 software to access the guided and open ended Science and Computational thinking projects together with the detailed tutorials with building instructions and detailed  programming examples for each model.

Examples of the WeDo 2.0 software Project Library, Design Library and Programming Library are shown below.


WeDo 2.0 is specifically designed for the younger children so teachers should have no trouble learning the programming of the robots with the visual, block based, drag and drop coding environment shown below. Introduce children to fundamental coding concepts such as sequences, loops, conditional statements and events to help develop their computational thinking processes in and engaging learning environment. There is a help system which explains in detail each programming block. Colour coded programming function blocks make it easy to find what you need. Simply drag the blocks onto the canvas and press the start block to see the robot in action. Learn from what happens and develop the code further.

The code below simply first writes the number 10 on the screen. The code within the loop (yellow icon with white arrows) then sets the motor speed to the number on the screen. The math screen function (with minus sign) then subtracts 1 from the number on the screen each time it runs through the loop. So the WeDo robot starts off at power level 10 and slows down progressively to power level 0 when both the robot and program stop.

Some of the projects have built in teacher assistant functionality to help plan and deliver the lesson by providing discussion topics, setting the scene, building and programming help together with skills development support for the areas of computational thinking, investigation, programming, design, modelling and communication.

The Lego Education website also has a great section with free lesson plans searchable by Subject type, Grade, Duration, Difficulty, Product and Course.

Lesson examples include projects such as designing and programming a glowing snail, a cooling fan, a moving satellite or a spy robot where students design and program a robot to make a sound when it detects something move in front of it. The project explains the requirements, has video examples, building instructions (if required) and possible programming solutions for the task. There are around 30 WeDo 2,0 projects to choose from and can be extended or simplified to suit your requirements.
