Yes …this is a bit tricky! See how you go.

# Wishball…take the challenge

**There are two links on the sidebar to Wishball or click on this image to test your knowledge of whole numbers.**

**Take the challenge!**

# Free Rice…try this.

I thought I might daw your attention to a site that is worth visiting. It is fun and educational. You can **improve your word knowledge** or **practise your tables**. Your participation assists the World Food program. Give it a go!

This website is listed under ‘site seeing’ on the blog side-bar **OR just click on the image below.**

**What do you think?**

# Money in the bank or money in shares

So…you have $1000 to spend ( in your dreams of course).

What do you do… invest in the sharemarket or play it safe and put your $1000 in the bank?

This prompts me to ask another question…how is your $3000 share portfolio ( virtual investment ) measuring up?

Have you made a profit or loss? I would really like to know.

And…following on from the discussion we had today about bank profit and interest payments, this Behind The News segment might be worth watching.

# Lemonade stand…profit or loss?

One Summer I remember ( I was about 11 ) setting up a lemonade stand with my brother and sister and the children from 2 other families who lived down the street where we lived.

Our special recipe consisted of water, freshly squeezed lemons and fruit saline ( the secret to our success).

We set up a card table out the front of our neighbour’s house, grabbed a number of glasses, ( back then honey and peanut butter was sold in jars that could be used as glasses once you rinsed them out) and made a sign using our Derwent pencils.

Our neigbours became our faithful customers. We made enough money each to buy an ice cream.My favourite was something called a ‘Cream Between’.

This probably sounds like a sad tale compared to the success you may have experienced playing the Lemondade Stand game. How successful were you?

** What did you learn from your analysis of the game?**

By the way….according to a very well know saying….”The customer is always right.”….epecially if you are a duck!!! This will make sense if you watch this video. *( courtesy of school tube )*

# Do the maths…clever calculating or careless error?

Watch the video below. and then, yes you guessed it, watch it again and probably again.

Can you explain why this maths appears to be correct?

Record the steps taken and be prepared to share your work and opinion in class next week.

# The Egg Of Columbus

The puzzle ‘Egg of Columbus’ appears at first glance to be a simple tangram puzzle. All you need to do is use the 9 pieces of the egg to create 6 basic shapes. You must use all of the pieces, none of which are allowed to overlap. Sounds easy???

It became very apparent, after a few short minutes that this egg puzzle was proving to be difficult to crack. The ability of students to persist and think creatively was being tested with the levels of frustration within the classroom rising with every minute.

Students achieved variable degrees of success. After all, we can’t all be spatially talented. Only a few children managed to find all six solutions. Most managed to complete three or four and came to the conclusion that just because something looks easy doesn’t mean that it is.

Oh…and for those few inquisitive students who wanted to know how the puzzle got its name… click here.

# Come In Spinner…What's the probability?

“Come in spinner” is a term that is associated with the game of Two Up. This is a uniquely Australian game in which bets are made on the chances of two coins falling with either heads or tails landing face up.

If you do the maths, then the chances of tossing a head or a tail should be 50/50. In reality this may not necessarily be true.

You should probably visit the link to “Adjustable Spinners”.

Oh…and don’t forget to do the maths!

# Analyse this…clever calculating or just another clever script.

View this classic ‘Ma and Pa Kettle’ video.

Ask yourself…does this make sense or is it mathematical nonsense?

Can you explain how Ma and Pa Kettle used what appears to be correct calculating to arrive at an incorrect answer ?

You have a whole week to do so.

A reward will await you!

# Microsoft Visio…

Microsoft Visio… This week we used this software to create a two dimensional representation of our bedroom. We needed to base our final plan on the real dimensions of the room ( measured in metres and centimetres), the furniture and other fixtures such as windows, doors and in one case…a peephole. We didn’t need to include such detail as the odd sock or two lurking under the bed or similar clutter.
