Week 7 - 8 Properties of shape

National curriculum content

  • Draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
  • Recognise angles as a property of shape or a description of a turn
  • Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle
  • Identify horizontal and vertical lines and pairs of perpendicular and parallel lines


Lesson objectives

  1. Turn and angles
  2. Right angles in shapes
  3. Compare angles
  4. Draw accurately
  5. Horizontal and vertical
  6. Parallel and perpendicular
  7. Recognise and describe 2-D shapes
  8. Recognise and describe 3-D shapes
  9. Make 3-D shapes


What we want children to know

  • Recognise angles as a measure of a turn
  • Understand that an angle is created when 2 straight lines meet a point
  • Recognise that a right angle is a quarter turn and 4 right angles make a complete turn
  • Identify whether an angle is greater than or less than a right angle in shapes and turns
  • Use the words ‘acute’ and ‘obtuse’ when describing angles
  • Measure and draw straight lines accurately in centimetres and millimetres
  • Identify and find horizontal and vertical lines in a range of contexts
  • Identify horizontal and vertical lines of symmetry in shapes and symbols
  • Identify and find parallel and perpendicular lines in a range of practical contexts
  • Recognise, describe and draw 2-D shapes accurately
  • Recognise and describe 3-D shapes in different orientations
  • Make 3-D shapes using construction materials
  • Use the correct mathematical language to describe the shapes they have made


What skills we want children to develop

Use knowledge to solve reasoning and problem solving questions such as:



I am thinking of a 3-dimensional shape which has faces that are triangles and squares. What could my shape be?


Other possibilities

One face of a 3-D shape looks like this… (a square)

What shape scould it be?

Are there any other possibilities?


Convince me

Which capital letters have perpendicular and/or parallel lines? Convince me.


Mathematical talk

  • Can you see any angles around the classroom?
  • Which shapes contain right angles?
  • Can you draw me a shape that contains acute/obtuse angles?
  • What do we call a line that is not horizontal or vertical?
  • Where might you see sets of parallel lines in the environment?
  • Can you guess the shape from the description given?
