Term 2 Week 4

We finish Geometry this week with a topic test.

The next topic is Percentages. See pages 109 - 137 of the text.

Percentage Trivia: The symbol for percent (%) evolved from a symbol abbreviating the Italian per cento.

Being able to convert things to percentages allows us to compare 'apples' with 'apples'.

For example if one person scores 10 goals out of 20 attempts, whereas another scores 9 goals out of 15 attempts we can work out who is the higher scoring player by converting their score to a percentage. In this case player 1 has a 50% score rate, whereas player 2 has a 60% score rate and is probably a better goal shooter.

Fractions and decimal values also allow us to compare things.

The purpose of this unit is to increase students capability to convert things to and from percentages, and compare them. This is very applied mathematics as we know that percentages and proportions come up quite frequently in every day life.
