Our teaching resources cover the topics of coordinate geometry, properties of geometric figures and probabilities in single and multi-step chance experiments from the Stage 4 and 5 New South Wales syllabus. The syllabus outcomes, shown below, are taken from the Mathematics K-10 Draft Syllabus – Version 2 (NSW Board of Studies, 2012, p. 304):
Coordinate Geometry:
·
Given
coordinates, plot points on the Cartesian plane, and find coordinates for a
given point (ACMNA178)
·
Plot
linear relationships on the Cartesian plane with and without the use of digital
technologies (ACMNA193)
·
Find
the midpoint and gradient of a line segment (interval) on the Cartesian plane
using a range of strategies, including graphing software (ACMNA294)
·
Find
the distance between two points located on a Cartesian plane using a range of
strategies, including graphing software (ACMNA214)
Properties
of Geometric Figures:
·
Classify
triangles according to their side and angle properties and describe
quadrilaterals (ACMMG165)
·
Describe
translations, reflections in an axis, and rotations of multiples of 90° on the
Cartesian plane using coordinates.
Identify line and rotational symmetries (ACMMG181)
·
Demonstrate
that the angle sum of a triangle is 180° and use this to find the angle sum of
a quadrilateral (ACMMG166)
Probabilities
in Single and Multi-step Chance Experiments:
·
Construct
sample spaces for single-step experiments with equally likely outcomes
(ACMSP167)
·
Assign
probabilities to the outcomes of events and determine probabilities for events
(ACMSP168)
·
Identify
complementary events and use the sum of probabilities to solve problems
(ACMSP204)
·
Calculate
relative frequencies from given or collected data to estimate probabilities of
events involving “and” or “or” (ACMSP226)
The main teaching focus used throughout
this project is group work. This
approach is particularly effective in learning mathematical concepts such as
coordinate geometry, properties of geometric shapes and probability, as group
work requires the students to be active learners. For this reason, Killen advocates that group
work “can enhance students’ achievement and retention” (Killen, 2009, p.
188). Furthermore, Roschelle et al.
(2009) suggest that mathematical group work tasks can be enriched by
incorporating technology, as we have done.
Amosa, Ladwig, Griffiths and Gore’s (2007) research proved that the Quality Teaching Framework also
greatly enhances student learning. As a consequence, we have endeavored to
incorporate a high level of intellectual quality and significance into the
lessons, as well as providing a quality learning environment.
