If the students were to tell somebody how to draw square how would the tell somebody to draw it. Have the students come up with an “algorithm” to draw a square. Work through YR1-2a to design simple shapes using algorithms.
Talk 2- Introduce the website design blocks; explain how to use it to create the simple shapes. Ask students to make the shapes using Design blocks. YR1-2b After that get student’s to draw a shape, create an algorithm for it and then try to make the program draw it. (YR1- 2c)
Plenary-Explain that computers when they are doing a task just run a program, which is just like a recipe or a set of instructions for a Lego model.
