Scratch: Challenges with Drawing Using Iteration (Loops)

KS3: The three challenges are graduated in difficulty, challenge 1 being the easiest. These can be used as one off exercises or as a pupil choice for a differentiated approach. Delivery can be set as individual work or ‘buddies’/peer-to-peer. Putting them in pairs for this exercise does work well in my experience. The outcomes can feed into a plenary to go over the steps involved in the construction of the shape. It lends nicely to a discussion of the mathematics involved in the angles used to draw the pattern in each challenge. Teacher solutions are part of this resource to enable a quick start and use in lessons. Teacher knowledge of the Scratch commands used in this resource is assumed.
