Homework Policy

Teachers should set homework on a regular basis.  The homework should be pertinent, gainful and achievable.

Year 7 will be given weekly review/enrichment sheets.

The amount of homework varies depending on the year and course.   As a guide Year 7 should be given 15-20 minutes homework each night, whilst senior students should be completing 30-45 minutes each night.

Teachers are expected to mark homework regularly, ascertain any problems arising and ensure completion.

Homework defaulters can be dealt with in various ways, but after three warnings concerning non-completion the Head Teacher should be informed, detention arranged and a note dispatched to parents.

Assignments are to be set as part of the assessment procedures in the junior years and are still part of a systematic revision program in the senior years.

 

 

Study Tips
 

*

 Do real Maths questions and indentify areas needing revision

*

See your teacher with questions you are unable to do

*

Set yourself time limits to simulate test situations

*

Learn your formulae

*

Complete questions from past exam papers

*

Revise a little each night rather than last week cramming

Complete the Chapter reviews from your textbook
    - least once per week
    - revisit as necessary

*

Use websites (eg www.hsc.csu.edu.au)
   

 

 

Divisibility Tests

Simple tests to find if the numbers 2 to 10 evenly divide into another number

 

Divisibility by 2

The last digit must be  0, 2, 4, 6 or 8   

For example, 2 000 346 as the last digit is 6

Divisibility by 3

Add the digits together and if the answer is divisible by by 3 then the original number is also divisible by 3

For example,   7 014      add  7+1+4   Is 12  divisible by 3 ? Yes, therefore 7014 is also divisible by 3.

Divisibility by 4

If the last two digits are divisible by 4 then the whole number is divisible by 4

For example, 1 007 124       24 is divisible by 4 therefore 1 007 124 is divisible by 4

Divisibility by 5

The last digit must be 0 or 5

For example, 1 098 625 is divisible by 5 as the last digit is a 5

Divisibility by 6

If it is divisible by both 2 and 3 it will be divisible by 6

For example, 129 012 is divisible by both 2 and 3 therefore its divisible by 6

Divisibility by 7

Double the last digit, subtract your new number from the remainder of the original number. If the answer is divisible by 7 then the original number is divisible by 7.

For example, 203   double the last digit 2X3=6 subtract this from the remainder   20-6=14. As 14 is divisible by 7 203 is divisible by 7

Divisibility by 8

If the last 3 digits are divisible by 8 then the entire number is divisible by 8

For example, 1 000 888 is divisible by 8 as 888 is divisible by 8

Divisibility by 9

Add the digits, if the answer is divisible by 9 the the original number is also divisible by 9

For example,7 038  7+0+3+8 since 18 is divisible by 9 then 7 038 is divisible by 9

Divisibility by 10

The last digit must be 0

For example, 1 007 120   is divisible by 10
