Metric units are based around the standard units of metre, gram and litre.

Kilo placed before a unit means 1000 times.

Imperial is a system of units for measuring, which was created in the early 1800s during the British Empire.

Problem solving with complex 2D shapes

In this unit, pupils built upon their prior learning of the area of different shapes. In the future unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.

In the prior unit, pupils derived the formula for the circumference and area of a circle. In this unit, this knowledge is combined with knowledge of fractions to find the arc length and area of a sector.

In this unit, knowledge of circles and polygons is drawn upon to find the arc length and area of a circle sector and areas of complex compound shapes.

2D and 3D shape: compound shapes

Imperial is a system of units for measuring, which was created in the early 1800s, during the British Empire.

An interval is the space between two values or points. On a scale, intervals are shown using a small mark or line to show the space between.

The perimeter is the distance around a 2D shape.

A compound shape is a shape created using two or more basic shapes.

A composite shape is an alternative for a compound shape.

The area is the size of the surface and states the number of unit squares needed to completely cover that surface.

An arc is part of a curve. An arc of a circle is part of the circle’s circumference.

A sector is the region formed between two radii and their connecting arc.

A chord is any line segment joining two points on the circumference of a circle.

The radius is any line segment that joins the centre of a circle to any point on its circumference.

The circumference of a circle is the perimeter of the circle.

An equation is used to show two expressions that are equal to each other.

An equation of a line is any equation whose graph forms a straight line. These equations can be written in the form y = mx + c.

A pie chart (pie graph) is a circular graph where sectors represent different groups proportionally.
