The Digital Technologies Hub have put together a Scope and Sequence resource for teachers. It is not an extensive resource, but a starting point for teachers to use. It provides a possible set of sequenced topics to address the new Technologies curriculum.
Pictured below is an outline of the Year 3-4 topics and associated topics.
When you click on a unit you are presented with an overview and the flow of activities. You can download the topic overview, unit overview, topic unit map, and Unit SOLO Taxonomy as a PDF or Word document format.
Clicking on the activities will give you a lesson outline.
This resource would be a good starting point for schools that are yet to formulate a scope and sequence in this area. It certainly can be built upon with further ideas and ways to achieve the learning outcomes.
Below is a quick video introduction to the resource.
