KS2 Maths is an important core subject in the National Curriculum and this area of the website covers all the major aspects of the curriculum including numbers, calculations, problems and measures. Each subject area is designed to help children develop their knowledge, whether they are learning in a classroom or home schooling environment.

At Key Stage 2 children are encouraged to engage in mental and oral work for their mathematics so this KS2 Maths area includes a collection of interactive activities to help develop both mental and oral skills.

A key requirement of **KS2 Maths** is the understanding of the Number and the Number System which includes counting, estimating & rounding, fractions, decimals & percentages, number patterns & sequences and place value & ordering. Within the Number and the Number System section children are able to practice their calculations in addition, subtraction, multiplication and division. The interactive activities help children to practice using a variety of calculation methods by encouraging the use of written calculation methods, mental calculations and using a calculator.

The **KS2 Maths** section also has a problem solving area to help children further develop their problem solving skills using numbers, money, measures and shape and space. There are many activities to help children test their knowledge, including a variety of problems using money in ‘real life´ situations.

The Measures area of the KS2 Maths section helps children to enhance their knowledge of length, mass & capacity, time, area and perimeter. The Shape and Space area includes useful information and activities relating to position and movement, 2D shapes, 3D shapes, symmetry, angles, co-ordinates and sorting.

Children are also able to learn about handling data through a number of activities based on interpreting and organising data as well as a section on probability.
