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 4 focuses on place value and requires the use of broadcasting to build place value models within several different contexts such as time and measurements.This product supports Module 4: Building with 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.
