Unit 4: Shapes

In this assessment you will be assessed on Criterion A: Knowing and understanding and Criterion B: Investigating patterns.

Assessment Checklist

To do well on this assessment you will need to do the following things:

Criterion A

• Successfully solve a range of familiar and unfamiliar problems of varying degrees of difficulty.

• Select the correct methods to solve these problems.

• Recall facts and methods regarding circles, polygons, coordinates and transformations.

Criterion B

• Successfully find rules and describe how they work in words.

• Explain the rules in a detailed and accurate way, using correct mathematical language.

• Support your work with tables of results and with diagrams where appropriate.

• Verify (check) that your rules work by comparing your drawings with the answers found using your rules.

• Justify (explain) why the rules work. 

• Use your rules to make predictions, and check if those predictions are correct.

Assessment Checklist

To do well on this assessment you will need to do the following things:

• Know the names of the different polygons up to and including a decagon.

• Calculate the (sum of) interior and exterior angles of any (including a regular) polygon.

• Apply angle rules for angles on a straight line, at a point, in a triangle, in quadrilaterals including those with special properties, and angles made by parallel and intersecting lines.

• Justify answers stating the angle fact used at each stage. 

• Understand what is meant by circumference, radius, diameter, chord, arc, tangent, semi-circle, quadrant, sector and segment, and be able to identify each on a diagram.

• Calculate the circumference, perimeter and area of a circle, semi-circles, sectors, including real life problems.

• Know how to plot and read points in all four quadrants of the Cartesian Plane.

• Determine whether or not a point lies of a particular line.

• Find the coordinates of a point on a particular line given one of the coordinates.

• Be able to calculate the gradient, equation and y-intercept of a straight line given two or more points.

• Plot a set of points and join them to form a straight line.

• Understand and be able to find equations of parallel and perpendicular lines.

• Recognise and use the equations of horizontal and vertical lines, including the x and y axes.
