– Key Stage 1

(KS1) is the legal term for the two years of schooling in maintained schools in England and Wales normally known as Year 1 and Year 2, when pupils are aged between 5 and 7. This Key Stage normally covers pupils during infant school, although in some cases this might form part of a first or primary school.  This where pupils learn the foundations of the core subjects and this is where scaffolding begins. 

In education, scaffolding refers to a variety of instructional techniques used to move students progressively toward stronger understanding and, ultimately, greater independence in the learning process
