NCEA and Careers Information

Here is that booket.
I know that students that can say "I really want to have a job in ? business" are way more likely to do better in school.  That is they're more likely to see reason for work in class and strive to get better grades.

Relief Lesson & Games

Decimal Conversion to Fraction

The trick with converting decimals is to know the smallest 'place value' and making that the bottom of the fraction (denominator).

Review on Place Value
For the number 45,268.137

• The four is in the tens of thousands
• The five is in the thousands
• The two is in the hundreds
• The six is in the tens
• The eight is in the ones (units)
• The one is in the tenths (as in fraction over ten)
• The three is in the hundredths (as in fraction over one hundred)
• The seven is in the thousandths (as in fraction over one thousand)

Another way to say this number is "forty five thousand, two hundred and six eight and 137/1000"

Here are some online games that practice this...

Fruit Shooting - ok game good practice.  Lots of levels to choose from. 

Puppy Chase - make the dog run (I got second when I tried it).

Jump Stones Over River - this tests out if you know your decimals

Balance the Scales - not so much a game but good to play with for few mins

Unit Plan

Fraction - Decimals - Percentages
Here is a copy of our last topic for the year.

Fractions

Fractions
Visual - Representative.

Fractions are things that confuse heaps of students... lots get through without ever really knowing what they're all about.  I always think about fractions with my stomach.  I think of bars of chocolate (cause they're rectangles) or cakes (cause they're round).

The key things you need to know is that they're parts of wholes.  They lie between the numbers on a number line...

They don't always have to be between 0 and one (e.g. you can have 'three and a half'.

Class activity - competition to see where a fraction of a line is on the whiteboard (some rewards up for grabs).  


Here is a link to a fraction shooting game (quite good fun).  Post a reply of your high score.  Set the timer on this one

This link is for one you need headphones for - it's about seeing what fraction is bigger.  Do this one for about 10 minutes - it's a bit boring but you'll learn a valuable ability to identify size.


Equivalent Fractions -

here is the link 

This is when the fraction shows the same amount of a fraction but looks different.  This is an interactive teacher led animation.  You can see how the fractions are the equal (balanced) but have different numbers top/bottom.  Other good learning here is the decimal on the bottom - you can use a calculator to find this (use the divided by button).
 
Here is a link to a game (bit boring but has levels of difficulty) - try to get through to level four.

Rest of Year Plan

Planning
We will finish off our Probability Unit with the test next week (Monday period three). 

The remainder of the year will be on Fractions - Decimals - Percentages and general revision of all the topics we've covered this year. 

Week Six
Monday 3 - Prob test
Tuesday 3 - Test returned and outline of the final topic. 
Wednesday 2 -
Thursday 1 -

Week Seven
Tuesday 3 -
Wednesday 3 -
Thursday 2 -
Friday 1 -

Week Eight
Wednesday 3 -
Thursday 3 - Activity Week (movie or paintball). 
Friday 2 - On Homunga Walk

Week Nine
Monday 1 - Fraction/Decimal/% test.
Thursday 3 - Gaming day. 
Friday 3 - Test return (then general maths fun).

Week Ten
Monday 1 - Last period of maths this year. 
Wednesday - Year 9 & 10 Prizegiving in the morning. 

Probability Post Two

Online Probability Apps.

Here are a couple of YouTube videos that may help you're understanding.  (Headphones needed)..

Here are list of good games or apps that will help with your understanding of probability...

Ten problem test on works click here.

Card game probability challenge click here.

Falling ball simulation click here.

The difference between theoretical and experimental probabilities. 
Theoretical - theory - in the head - idea.
Experimental - from the past experiment.

The idea you need to know is that with time experiment will become theoretical.  The probabilities will match.  e.g. flipping a head (should be 50%)...  There are two sides on a coin one is a head therefore in theory it's 1/2 chance. 

The proper notation is to save time.   P(head) = 0.5   this means "the probability of a head is 50%"

Card Games - we think no jokers so 52 cards.  Four suits (hearts/clubs/spades/diamonds).   Picture cards (king/queen/jack).
