A complete, standalone lesson for Y3/4 in which pupils design a ‘room-cleaning robot’ and then use this as the context for an explanation text on how the robot functions. This can be done as an assessed piece in one extended lesson or the content could be split into separate planning and writing days. The resources comprise: an example text (WAGOLL), wordbank, design template, planning (‘flowchart’) template, L.O page header slips and a step-by-step powerpoint.
