UCL ScratchMaths is a set of sequenced materials designed to engage 9-11 year old children with mathematical concepts through their exploration using pre-built progams in Scratch. Children not only develop key mathematical skills but also crucial computational concepts. Module 6 centres around coordinates within multiple contexts firstly to investigate emerging shapes through the use of randomness, then to manipulate triangles and quadrilaterals and finally to explore different transformations such as translations and reflections.For additional help, view Module 6: Coordinates and Geometry – Supporting Scratch Maths uses the free of charge Scratch programming language. It is recommended to use a device with a physical keyboard and to use the Free Kindle Reading App for Mac or the Free Kindle reading App for PC. Scratch is currently available on desktops and mobile devices with Scratch 3.0. However, mobile devices cannot use keyboard controls, which are essential for many projects. Scratch is currently not available as a mobile app, though the Scratch Team is developing an app for larger mobile devices.
