United Kingdom – National Curriculum

  • KS2 – Key Stage 2
    • KS2.Ma3 – Shape, space and measures
      • Knowledge, skills and understanding

        • Understanding measures

          • KS2.Ma3.4 – Pupils should be taught to:

            • KS2.Ma3.4.c – Recognise angles as greater or less than a right angle or half-turn, estimate their size and order them; measure and draw acute, obtuse and right angles to the nearest degree

Australia – Australian Curriculum

  • Year 5
    • Measurement and Geometry
      • Geometric reasoning

        • ACMMG112 – Estimate, measure and compare angles using degrees. Construct angles using a protractor

  • Year 6
    • Measurement and Geometry
      • Geometric reasoning

        • ACMMG141 – Investigate, with and without digital technologies, angles on a straight line, angles at a point and vertically opposite angles. Use results to find unknown angles

New Zealand – National Standards

  • 6 – Year 6
    • 6.GM – Geometry and measurement
      • 6.GM.3 – Sort two- and three-dimensional shapes (including prisms), considering given properties simultaneously and justifying the decisions made

  • 7 – Year 7
    • 7.GM – Geometry and measurement
      • 7.GM.4 – Sort two- and three-dimensional shapes into classes, defining properties and justifying the decisions made

United States – Common Core State Standards

  • 4 – Grade 4
    • 4.MD – Measurement & Data
      • Mathematics

        • 4.MD.6 – Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

        • 4.MD.5 – Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

          • 4.MD.5.a – An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

    • 4.G – Geometry
      • Mathematics

        • 4.G.1 – Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

  • 5 – Grade 5
    • 5.MD – Measurement & Data
      • Mathematics

        • 5.G.3 – Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

        • 5.G.4 – Classify two-dimensional figures in a hierarchy based on properties.
