Year 7 Mathematics Mainstream 

TERM 3, 2025

Data Visualisation and Analysis

Students will learn how to:

• Classify data as numerical (discrete or continuous) or categorical (nominal or ordinal)

• Display data using appropriate graphical representations including frequency histograms and polygons, dot plots, stem-and-leaf plots, divided bar graphs, line graphs, sector graphs and pictograms.

• Interpret a wide variety of graphical representations and develop skills in graph comprehension.

• Represent a single dataset using an infographic.

• Identify and describe how graphical representations can be misleading.

Angles and Shapes

Students learn how to apply mathematical techniques to solve problems and at the end of the unit students can:

• Use relevant notations, language and conventions for angle relationships, including parallel and perpendicular lines.

• Describe and identify geometrical properties for angles at a point.

• Apply properties of parallel lines cut by a transversal to solve problems.

• Determine and justify whether 2 lines are parallel.

• Use given information to find sizes of unknown angles in a visual representation.

Length, Area and Volume

Students learn how to:

• Solve problems by finding the perimeter of plane shapes and composite figures involving quadrilaterals.

• Find the areas of composite shapes consisting of triangles, rectangles and parallelograms.

• Use and convert between appropriate units of measurement.

• Identify, describe and represent different views of a right prism.

• Apply the formula to find the volume of a right prism.

• Choose appropriate units for volume and capacity and convert between them.

• Identify the difference between volume and capacity and solve related problems.
