S2.N5.a Use algebra manipulatives, e.g. algebra discs to explain the process of expanding the product of two linear expressions of the form px + q, where p and q are integers, to obtain a quadratic expression of the form ax² + bx + c.
S2.N6.a Play games, e.g. Battleship Game, that involve the use of 2D Cartesian coordinates to specify points.
S2.N6.b Use a function machine to generate input and output values to illustrate the concept of function as "only one output for every input" and represent the function in verbal, tabular, graphical and algebraic forms.
S2.N6.c Use a linear function to represent the relationship between two variables (such as distance and time when the speed is constant), show the relationship graphically and identify that the rate of change is the gradient of the graph.
S2.N7.a formulate inequalities from real-world contexts.
S2.N7.b Use Graphmatica, applets or other software to draw the graph of ax + by = c (a straight line), check that the coordinates of a point on the straight line satisfy the equation, and explain why the solution of a pair of simultaneous linear equations is the point of intersection of two straight lines.
S2.N7.c Draw the lines x = a and y = b, and describe the lines and their gradients.
S2.G4.a Either (i) use a string of length 12 units (e.g. 1 unit = 10cm) to form a right-angled triangle with sides of whole-unit lengths (e.g. 3 units, 4 units and 5 units) and find out if there is a relationship between the three sides; or (ii) use cut-out pieces of two squares with sides of 3 units and 4 units respectively to form a square of sides 5 units.
