Shape and space in the primary curriculum

Lines and angles - fifth and sixth class

Content for fifth class

The child should be enabled to

• Recognise, classify and describe angles and relate angles to shape and the environment?
Explore and compare a wide variety of angles and shapes measure and record angles as acute, obtuse, reflex or right angles, and determine the number of such angles in relation to common regular shapes?
• Recognise angles in terms of a rotation.
Examine, measure and record the angles (including the reflex angle) formed by the hands of a clock at a variety of different times.
Extend by using manipulatives, e.g. straws, lollipop sticks, Meccano, string, 360 protractor, LOGO computer language if available?
• Estimate, measure and construct angles in degrees?
Measure and record a wide variety of angles using a protractor.
Construct angles of various sizes using a protractor.
Estimate angle sizes and check by measuring with a protractor.
• Explore the sum of the angles in a triangle?
Cut off the three corners of a paper triangle and put them together to make 180 degrees.
Measure the angles in a variety of triangles using a protractor.
Calculate and record their sum.
Examine and discuss results.

Content for sixth class

The child should be enabled to

• Recognise, classify and describe angles and relate angles to shape
e.g. identify types of angles in the environment?
• Recognise angles in terms of a rotation?
• Estimate, measure and construct angles in degrees
• Explore the sum of the angles in a quadrilateral?
Cut off the four corners of a paper quadrilateral and put them together to make 360 degrees. Measure the angles in a variety of quadrilaterals and calculate their sums.
