Triathlon

Students explore data analysis, distance-time graphs, distances, gradients, line graphs, number patterns and speed.

The activities focus on the use of distance-time graphs to represent the performance of an athlete in the three disciplines of the triathlon event: swimming, cycling, running.
Students are introduced to the significance of various aspects of a graph: axes (what they represent); the graph line (using a single athlete); slope of line - as indication of speed; straight line - as an indication of an unchanging distance with time still elapsing and relative scale sizes.
Students interpret graphs: identifying points at which certain events occur and answering questions regarding speed, distance, time and altitude.
In 'Triathlete', 'elite triathlete 'and 'the course', students answer questions using graphs then complete a report using the facts they have established from the graphs.

	Triathlon: distance-time graphs Students are introduced to introduced to the basic attributes of distance-time graphs and observe the significance of slopes and speed.
	Triathlon: triathlete Students analyse the performance of a single athlete (either male or female) in one of two locations (Hawaii and Auckland). A printout of the student's report is available.
	Triathlon: elite triathletes Students analyse and compare the performances of four athletes (either male or female) in one of four locations (Hawaii, Auckland, Sydney and Perth). A printout of the student's report is available.
	Triathlon: the course Students analyse and compare the performances of an athlete using two graphs, distance-time and distance-altitude. A printout of the student's report is available.
