7 Summer 1

Lines and Angles

OVERVIEW

Students will build on their KS2 skills using rulers and protractors to construct and measure increasingly complex diagrams using correct mathematical notation. This will include three letter notation for angles, the use of hatch marks to indicate equality and the use of arrows to indicate parallel lines. Pie charts will also be studied here to gain further practice measuring and drawing angles. Basic geometric language, names and properties of types of triangles, quadrilaterals and polygons will be introduced this half term. Angle relationships will be built on from knowledge and understanding from KS2 to include the use of parallel lines.

Please see here for additional medium term plans and resources including LPA & HPA guidance, further exemplar questions, worksheets and videos.
