Standard metric units will be used confidently including conversions (eg 2.76 litres to 2760 ml). Finding the area of more complex 2D shapes, including compound shapes and the surface area of 3D shapes is part of the year 6 programme. By the end of the year children will be confident estimating angles and using a protractor to accurately measure angle. They will be able to calculate the angles in a triangle or around a point.
Converting imperial units to metric units and metric units to imperial.
Finding fractions of metric units and converting from large units to small and vice versa.
Some tricky problem solving on length, weight and capacity. Also introducing Newtons.
Small items can be measured by putting several together and measuring all of them, and then dividing by the number there are. Giving measurements of length in millimetres and metres.
More on reading and interpreting scales using weight and length.
More on units of measurement and rounding to the nearest unit and tenth of a unit.
Finding the area of rectangles or, given the area, finding the lengths of the sides.
Sometimes shapes are made up of two or more rectangles. These shapes are known as compound or composite shapes. To find the area of a shape like this you need to divide it into rectangles.
When working out the surface area of a cuboid (box shape) you need to think that there are three pairs of opposite sides and each side of a pair will have the same area.
The area of a triangle equals half the base times the height.
Investigating the circumference and diameter of circles.
Knowing that pi is equal to 3.14 can be very useful. If you know the diameter of a circle you can use it to work out the circumference.
