Shape and space in the primary curriculum

2-D shapes - fifth and sixth class

Content for fifth class

The child should be enabled to

• Make informal deductions about 2-D shapes and their properties
• Use angle and line properties to classify and describe triangles and quadrilaterals.
Name, explore and compare a wide variety of three and four-sided figures in terms of size and number of angles, type and number of sides e.g. trapezium, scalene triangle and regular hexagon?
• Identify the properties of the circle?
Explore and compare circles of various unit diameters?
Measure and identify the relationship of diameter to radius?
Examine area by counting square units?
• Construct a circle of given radius or diameter?
Draw using a compass.
• Tessellate combinations of 2-D shapes
• Classify 2-D shapes according to their lines of symmetry.
Explore, compare and record lines of symmetry in 2-D shapes?
• Use 2-D shapes and properties to solve problems.
Make a specified shape with Tangram shapes.

Content for sixth class

The child should be enabled to

• Make informal deductions about 2-D shapes and their properties
• Use angle and line properties to classify and describe triangles and quadrilaterals
• Construct triangles from given sides or angles.
Complete the construction of triangles, given two sides and the angle between them or given two angles and the line between them.
• Identify the properties of the circle?
Relate the diameter of a circle to its circumference by measurement.
Measure the circumference of a circle or object such as a rolling-pin or wheel e.g. using a piece of string.
• Construct a circle of given radius or diameter?
• Tessellate combinations of 2-D shapes
• Construct a circle of given radius or diameter?
• Classify 2-D shapes according to their lines of symmetry
• Plot simple co-ordinates and apply where appropriate.
Use geoboards and squared paper.
• Use 2-D shapes and properties to solve problems.
