Tasks - Early Adolescence

Rate   by Alan Sadler, Rossmoyne SHS

Phase of Development:   Early Adolescence

Learning Area/s:	Mathematics
Strand/s	Number	Working Mathematically
Substrand/s	Understand Operations	Contextualise Mathematics
Brief Description:	Use of computers to access information.
Expected Outcomes:	Uses ratios and rates to describe the relationship between two quantities and finds one quantity from another in situations where familiarity with context helps understand the ratio or rate. Compares the way in which familiar mathematics is done or used in own and other communities.
Context:	In this activity I attempt to show how teachers can do what they are doing now but use learning technology as an information source.
Learning Activities/ Experience:	Initial discussion about RATE using focus questions such as: What is a rate? What are these rates likely to be referring to: Words/minute Bricks/hour People/km2 Spoonfuls/litre M/sec At what speeds do the following move: Person walking Car travelling Ships travelling Space shuttle A bullet A missile 100m world record Light Concorde Some of these focus questions will need research to answer and that is when encyclopaedias on CD Rom or Internet should be used. Can have one big screen TV with a student doing the search for all to see or could have small groups researching and reporting back. Other research questions: What are the speed limits in other states/countries What are the "breathaliser levels" in other states/countries How long does it take the space shuttle to circle the earth How long does it take light from the sun to reach us?
Resources:	Learning Technologies - Internet access, Encyclopaedias on CD-ROM, one big demo TV and/or a few other small group access points.
