Number and Algebra — Money and financial mathematics<br />

School fete finances<br />

Merrick Valley School is planning a school fete to raise<br />

funds to buy equipment for the school.<br />

As part of the fundraising activities, all classes will<br />

have a stall which they will stock with saleable goods.<br />

Some stalls will be stocked with donated goods. All<br />

money raised from these stalls will be income with<br />

no expenditure for materials or ingredients. All the<br />

money raised from these stalls becomes the profit.<br />

Other stalls, however, will be stocked with goods that have been<br />

made with materials bought by the students. <strong>The</strong> amount of<br />

money raised will depend on the cost of buying materials and<br />

how much the goods are sold for. <strong>The</strong>se stalls will have some<br />

expenditure and some income. <strong>The</strong> profit is the income minus<br />

any expenditure.<br />

Mrs Bowen’s <strong>Year</strong> 5 class are making iced cupcakes for the cake<br />

stall. <strong>The</strong>y are buying all the ingredients and making them in<br />

class on the morning of the fete.<br />

<strong>The</strong>y have decided to package<br />

and sell the cupcakes<br />

individually, in pairs, and in<br />

boxes of six. <strong>The</strong>y plan to<br />

make six dozen cupcakes.<br />

<strong>The</strong> total cost of the<br />

ingredients was $18.60.<br />

agreed to finance each class stall with<br />

an initial donation of $20.00 towards<br />

Card 1<br />

Bumbling Merv Measure was such a mess.<br />

He didn’t know how to measure and he really couldn’t care less!<br />

He’d initially made some attempt to learn but the results were far from pleasing.<br />

What happened was so comical that his friends couldn’t resist some teasing.<br />

Merv was quite a clever fellow, but when it came to measuring, he just didn’t get it!<br />

Finally, I think he said to himself, ‘I’ll choose what I like, and I won’t regret it!’<br />

So, in his bumbling fashion, he chose whatever unit came to mind<br />

To measure whatever he needed to at that particular time.<br />

Now Merv can say with pride he has possessions like no other—<br />

A shaggy toothbrush 190 kilometres long, a 1828-metre brother,<br />

A garden fence 20 millimetres wide, a fluffy cat 350 metres tall<br />

And a colourful painting 60 kilometres wide decorating his bedroom wall.<br />

Please take my advice and don’t be like Merv Measure<br />

Who chooses any measurement unit at his leisure!<br />

Don’t be a buffoon like this bumbling fool!<br />

To measure correctly, use the correct unit and tool!<br />

Nature displays a surprising number of mathematical elements, symmetry being one of<br />

them. Consider the reflectional (line) symmetry of the butterfly and the avenue of trees,<br />

Reflectional (line) symmetry<br />

occurs when the size, form and<br />

arrangement of parts of a shape<br />

or object on opposite sides of<br />

a line correspond. Each half is a<br />

mirror image of the other.<br />

rotated around a fixed point.<br />

angle measuring 90°’?<br />
