Hi maths class,

Your team is to create a fact sheet and a written description for you property before it goes on the market. There are a number of things potential buyers will want to know that you will need to put in your report.

- Perimeter of the floor plan - Area of the floor plan - Area of the outside walls (faces) - Area of roofing (faces) - Total number of faces, edges and vertices - Volume of your house (this is tricky) Use this to assist you with calculations.


 * **Shapes ** || **Formula ** ||
 * || **Rectangle: ** Area = Length X Width A = lw Perimeter = 2 X Lengths + 2 X Widths P = 2l + 2w ||
 * || **Parallelogram ** Area = Base X Height a = bh ||
 * || **Triangle **Area = 1/2 of the base X the height a = 1/2 bh Perimeter = a + b + c (add the length of the three sides) ||
 * || **Trapezoid ** ** Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c ** ||
 * || **Circle **[|**Try the Online tool.**]** The distance around the circle is a circumference. The distance across the circle is the diameter (d). The radius (r) is the distance from the center to a point on the circle. (Pi = 3.14) More about **[|**circles.**]** d = 2r c = pd = 2 pr A = pr2 (p=3.14) ** ||


 * Volume**
 * || **Rectangular Solid ** Volume = Length X Width X Height V = lwh Surface = 2lw + 2lh + 2wh ||
 * || **Prisms **<span style="color: #333333; font-family: "Verdana","sans-serif"; font-size: 13.32px;"> Volume = Base X Height v=bh Surface = 2b + Ph //(b is the area of the base P is the perimeter of the base)// ||

The areas of the triangular faces will have different formulas for different shaped bases. ||

Good Luck!

Hi Maths group! I would like you to use everything you have learnt about fractions and equivalent fractions to play these games. Choose either this fractions board game [] Or this fraction multiplication soccer game [] If you finish, try this with a partner []

2/11/2012 Hi mathematicians, We have begun work on shapes and should each have a 3D shape made from a 2D net. Using your net (if you have more than 1 select your favourite) you are to write a __DETAILED__ description. Study your shape and include anything you find interesting or unique. Some information you must include is. - Number of vertices, faces and edges - Lines of symmetry - The different types of shapes - Where you might find a similar shape in the world/what does it remind you of? Look for as many other features as you can – remember, I want you to be detailed!

When you finish your description, find a peer who has also finished and does not know your shape. Read your description and see if they can guess what your 3D shape might be.

Hi maths group, We have begun work on adding, subtracting and multiplying like, related and unrelated fractions. Hit the links below and complete the list of questions.

Complete working in your maths book as well as entering the answers on the internet. Make a note of the questions you got correct.

If you finish these questions, have a go at the 2 questions I have written for you as a challenge.

Greg swam 3/5 of the way down the swimming pool before he got tired and turned around to come back. He swam back 1/11 before stopping. Which is closer for him to swim to? - Show your working (try estimating first)

Wes was born 3/8 of the way around the entire world. Thomas was born 1/30 as far as Wes. What fraction of the total distance around the world was Thomas born? Challenge - the total distance around the world it 40000km, how far were they both born?

Papa Pete's pizza started the night with 8 and 1/2 pizzas. Through the night he sold 2 and 5/8 pizzas. How much pizza is left at the end of the day?

Good morning maths group!

Today we will be continuing with our "real life maths" that we were enjoying, using the Herald Sun newspaper. When percentages are presented as a discount or increase by 10% 20% - we had success!!

Now its getting trickier, and these websites are going to be useful in helping us work out harder problems.
