Key Stage 2 is the four years of schooling in maintained schools in England and Wales normally known as Year 3, Year 4, Year 5 and Year 6, when pupils are aged between 7 and 11 years.
During KS2 students become much more confident with maths: they are adding, subtracting, multiplying and dividing, as well as doing mental calculations and solving problems using time, measure or money.
By the end of Year 6, students should have a secure grasp of their times tables up to 12.
At the end of KS2, students sit SATs exams which are sent away to be marked externally.
