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.

This extension activity features in the upper-primary Blockly course, by the Rapid Router team at Code for Life. It explores the limits of generalised solutions, introducing children to the idea of algorithm testing and debugging. Children are asked to apply logical thinking to different problems, and analyse what...

This activity makes the leap from Blockly to Python programming. The 'grocery van driving challenge' is reduced from previous lessons to allow students to concentrate on syntax and correct coding using a limited set of instructions. Matching of Blockly and Python code is encouraged to assist the transition.

This Rapid Router lesson uses the Blockly language to develop ideas about selection, repetition, and conditionals. Children progress from specific instructions to spot patterns that can be made into generalised solutions. This important step helps learning about abstraction and pattern generalisation, two...

This activity in the Rapid Router series takes children further in their transition to text-based programming in Python.

By creating Blockly programs and comparing them to the automatically-generated Python code, children are encouraged to identify code which matches. The complexity of the problems is...

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...

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.

A basic lesson that introduces the idea of algorithms and simple sequences of commands. The online Rapid Router environment is introduced, after the children use some 'unplugged' activities to develop their thinking.

This activity follows-on from previous exercises using the Blockly editor on the Rapid Router website. It reviews what the children have learned before they proceed to using text-based programming.

The exercise looks at the most advanced ideas used with the Blockly-based phase of the Rapid Router scheme,...

In this activity, involving on-screen programming using Rapid Router, children will develop their understanding of programming principles by learning how to use repeat loops, if statements and respond to changes in variables in a visual programming language.

The activities focus on driving a delivery van...

This activity goes further into Python programming by expanding the range of repetition and selection commands used. Students also practice debugging of code.

Variables are explained before making use of incremented variables to solve challenges in Python.

Other programming practices, including...

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...

This lesson activity further develops Python programming ability by introducing additional commands such as WHILE, IF, ELSE and ELIF. Debugging of programs is featured, and extension activities lead to the writing of functions that use COUNT IN RANGE() to control repetition. Students are also encouraged to mark-up...

This activity, one in a series, uses traffic lights and control of vehicles to explore if-else, if, and wait commands, and to learn about variables.

A set of onscreen programming challenges are supported with teacher guides, worksheets, model solutions, assessment activities, wall displays and overview...
