Know that a square is a rectangle in which the four sides are of equal length

Maths

Make different sized angles by rotating two lines around a fixed point

Identify and describe right angles

Know that a right angle describes a quarter turn

Identify properties of triangles

Identify properties of quadrilaterals

Know that a rectangle is a four-sided polygon with four right angles

Investigate the shapes made when rectangles are cut on the diagonal

Join four right angles at a point using different right-angled polygons

Investigate and draw other polygons with right angles

In this unit pupils will rotate two lines around a fixed point to make different sized angles. They will identify vertices. In the future unit pupils will investigate ways to compose and decompose polygons. They will investigate quadrilaterals with and without parallel and perpendicular sides.

In the prior unit pupils ordered and arranged combinations of objects in patterns and sequences. They consolidated understanding of whole, half, quarter and three-quarter turns, in terms of right angles, using mathematical vocabulary to describe position, direction and movement. In this unit pupils will rotate 2 lines around a fixed point to make different sized angles. They will identify vertices

In this unit pupils will rotate 2 lines around a fixed point to make different angles. They identify vertices and describe half, quarter and three-quarter turns in terms of right angles.

Right angles

They have exactly two lines of symmetry. 

They have 4 sides that are equal in length.  

Which of these statements are true for all squares?

How many lines of symmetry does a square have?

Look at this pattern. How many squares are there altogether?

Which of these shapes are quadrilaterals?

Which of these shapes are not rectangles?

How many right angles does this shape have?

True or false? This shape has one line of symmetry

How many right angles do these three shapes have in total?
