Week Nine - Thursday 1st April

Today we had our test for number. Results will be out early next term. Next term we will begin with algebra!!!

Congratulations to Tevin and Hayley C who won the prize for best homework this term. Well done!

Homework for the holidays:

• check you are up to date with homework. You should have finished chapters 3, 4, 5 and 33.


• use the CD to mark all of your homework.


• HAVE A GREAT TIME!

Week Nine - Tuesday 30th March

Today we continued to prepare for our test. We worked on our practice tests, and also looked back at some previous homework.

There is no homework for tonight - but you should be studying chapters 3, 4 and 5 for the test on Thursday.

Week Nine - Monday 29th March

Today we began our revision for our test on Thursday. I handed out a worksheet that covered decimals, fractions, ratios and percentages - which is what you will be assessed on.

Remember to bring this sheet and your homework books (if you haven't already handed them in) tomorrow.

Study hard!

Week Eight - Friday 26th March

Today we learned about using ratios to split up amounts fairly. Note that fairly does not always mean in half!

e.g Split $150 in the ratio 3:7.
3+7=10. This will be the denominator (bottom number) for my fractions.
3/10 x 150 = $45. 7/10 x 150 = $105
Double check: $45 = $105 = $150

Homework: ex 6.03
Remember to bring your homework books on Monday as we will be using them to study for the test.

Reminder: ask your parents about interview times and grab one from me.

Week Eight - Thursday 25th March

I will not be here on Thursday as I am on a course. We will cover rates.

Homework: 5.04

Total homework due on Friday: 4.09-4.11 & 5.01 & 5.04

You MUST bring your homework book and remember to get it signed please.

Week Eight - Tuesday 23rd March

Today we introduced ratios. Ratios are a way of showing how one amount compares to another. e.g if red paint: white paint is 1:8 that means we have 1 bucket of red paint for 8 buckets of white paint, or 1 cup of red paint for 8 cups of white paint. This is not the same as 8:1. 1:8 would make a very light pink (lots of white), 8:1 would make a very dark pink (lots of red).

Ratios can be simplified just like fractions. e.g 4:10 becomes 2:5 by dividing both parts by 2.

Ratios should be in the same units. e.g 3m:70cm = 300cm:70cm = 30:7 after dividing by 10.

Homework: 5.01

Week Eight - Monday 22nd March

Today we studied GST (goods and services tax), this is a tax on almost everything that is bought and sold. Currently the GST rate is 12.5% in New Zealand. We calculate GST in the same way as normal percentages.

e.g: to find the GST on a TV costing $3200 before GST, we calculate 0.125 x 3200 = $400

e.g: to find the price including GST on a TV costing $3200 before GST, we calculate 1.125 x 3200 = $3600. (note this is the same as adding the $400 GST on to the original $3200).

e.g: to find the price without GST of a swimming pool if the GST inclusive price is $13500, we calculate 13500 / 1.125 = $12000

Homework: 4.09
You should now have completed all of chapter 4.

Remember to get the sheet in your homework book signed.

Week Seven - Friday 19th March

Today we studied two things: simple interest and finding the original amount.

Simple interest is calculated using the formula I = PxRxT/100.
Where I is the interest, P is the principal (the amount you invest), R is the rate of interest and T is the time the money is invested for measured in years.

Finding the original amount is the opposite of what we have studied so far. To find 20% of 70 we did 0.2 x 70 = 14. The opposite of times is divide. So if 20% of something is 14 we find that something by calculating 14/0.2 = 70.

Homework: 4.10 and 4.11

Some people still need to show me last weeks homework (4.07 and 4.08) or the week before (3.13-4.06). Get this is quick please!
