Session Four: Creating Simple Algorithms to Reach a Single Destination Along the Shortest Route

In the 4th lesson of a series for lower primary school computing, children use the online Rapid Router environment to learn more about algorithms. They learn that there can be more than one algorithm to achieve the same outcome, and that these can be selected according to efficiency. They further debug sequences in...

Session Five: Create a More Complex Algorithm to Deliver One or More Packages on the Way

The 5th lesson in the Rapid Router series adds complexity to algorithms, raising the level of challenge and building on familiar contexts from earlier activities.

Also included are wall displays, teacher and peer assessment sheets, worksheets and model solutions.

Session Six: Delivering Several Packages in a Sensible Sequence

This extension activity, from the Rapid Router Key Stage 1 course using Blockly, adds further complexity and challenge to simple sequenced commands.

Paired programming and unplugged activities build understanding of algorithms, with consideration of complexity and efficiency.

Included are wall...

Session Seven: Introducing the Repeat Code

The 7th lesson in this Rapid Router course using Blockly brings repetition to algorithms. Children use repeat to make simple sequences of commands shorter and more efficient.

The resource includes worksheets and model answers, assessment sheets and wall displays.

Session Eight: Follow-On and Extension Work on Multiple Repeat Loops and Nested Repeats

Lesson 8 in a series of lessons using Rapid Router, the game-like environment for learning programming. This session takes loops and repetition further, and includes reusing statements and nested loops.

The resource includes wall displays, worksheets, model answers and assessment sheets.

Session Nine: Children Create Their Own Routes

This lesson, in the Blockly Rapid Router series, challenges children to create their own maps which are then offered to classmates to solve. Creating the maps requires logical...

Session Ten: Try Out a Partner’s Route

This lesson utilises challenges created by children during lesson 9 of the Blockly 'Rapid Router' course. While attempting to follow a programming challenge written by someone else, debugging skills and logical thinking are encouraged. Children are also required to use loops and other constructs independently....

Session One: Recap on Using a Simple Repeat Loop

This lesson recaps some of the learning from the Key Stage One Blockly course on Rapid Router. It touches on repetition in programs, and requires children to create an algorithm challenge that requires loops to solve it efficiently. The challenges are in the context of programming a groceries delivery van.


Session Two: Using Repeat with a Condition on a Simple Route

The second lesson using Blockly in upper primary within the Rapid router game-like environment. This activity introduces conditional repeat statements that loop until a condition is met. Videos are included that explain to children why conditionals are useful. Also included are worksheets, assessment forms, model...

Session Three: Using Simple Selection and Repetition

This Blockly lesson from the Rapid Router course examines selection using IF statements. Nesting IF statements within loops is also studied, and a video explains the importance of selection in programs.

An 'unplugged' activity reinforces understanding before the children code their solutions in Rapid Router...
