Pikelets on Friday, 29 Aug. Period 4 in V5You will need the ingredients below plus fillings per group. Mrs Nathan will bring the ingredients, including milk, surviettes and eggs but groups will be required to bring self-raising flour, sugar, butter (100g max) to cook and other fillings. Also one measuring cup per group (I will bring my one just in case).We also need plates, plastic knives and forks.Groups of 5 (4 groups in total)

TARA: Jessica G, Cassie, Caitlin, Emma, Abbey

MELE: Karleen, Jessica L, Amber, Venezia, Ellen, Mercede

MANYA: Dana, Nicole L, Pascalle, Jenny, Leesha

SADAF: Rebecca, Charmaine, Khadija, Veronica, Hineari

Pikelet Recipe:You need to be able to find the Perimeter and Area of a rectangle/square, Area of a parallelogram, Area of a triangle, Circumference (perimeter of a circle), Area of a circle, Vol.PerimeterTo find the perimeter of a shape you have to measure the line around the outside of the shape. eg if you have a square with four sides the length of 5cm you would have to add the numbers up. 5+5+5+5=2

BY EMMA ADAM

Area of a rectangleThere is more than one way to the find the area of a rectangle. One way is to multiply the width by the length.

How to measure using cm and mm with a ruler AND Measuring in millilitres (ml):

Try this pre-test:

Try this Measurement Practice TestOn this sheet you can practice conversions and finding the area of a triangle and parallelogram:

## Perimeter

## more ...

The distance around a two-dimensional shape.

Example: the perimeter of this rectangle is 3+7+3+7 = 20

The perimeter of a circle is called the circumference

## Area of Plane Shapes

Learn more about Area, or try the Area Calculator.Area = ½ × b × h

b = base

h = vertical height

Area = a2

a = length of side

Area = w × h

w = width

h = height

Area = b × h

b = base

h = vertical height

Trapezium (UK)

Area = ½(a+b) × h

h = vertical height

Area = π × r2

Circumference = 2 × π × r

r = radius

Area = πab

Area = ½ × r2 × θ

r = radius

θ = angle in

radianshis at right angles tob:## Example: What is the area of this rectangle?

The formula is:

Area = w × h

w = width

h = height

We know

w = 5andh = 3, so:Area = 5 × 3 =

15## Example: What is the area of this triangle?

Height = h = 12

Base = b = 20

Area = ½ × b × h = ½ × 20 × 12 =

120A harder example:

## Example: Sam cuts grass at $0.10 per square meter

## How much does Sam earn cutting this area:

Let's break the area into two parts:

Part A is a square:

Area of A = a2 = 20m × 20m = 400m2

Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m.

Area of B = ½b × h = ½ × 20m × 14m = 140m2

So the total area is:

Area = Area of A + Area of B = 400m2 + 140m2 = 540m2

Sam earns $0.10 per square meter

Sam earns = $0.10 × 540m2 = $54

## Volume of a Cuboid

A cuboid is a 3 dimensional shape.So to work out the volume we need to know 3 measurements.There are 3 different measurements:

Length, Width, Height

Volume = Length × Width × Height

Which is usually shortened to:

V = l × w × h

Or more simply:

V = lwh

## In Any Order

It doesn't really matter which one is length, width or height, so long as you multiply all three together.## Example: Lengths in meters (m):

10 m × 5 m × 4 m =

200m3It also works out the same like this:

4 m × 5 m × 10 m =

200m3Note: the result is in

m3(cubic meters) because we have multiplied meters together three times.## Time - AM/PM vs 24 Hour Clock

Normally the time is shown asHours:MinutesThere are 24 Hours in a Day and 60 Minutes in each Hour.

Example:

10:25means 10 Hours and 25 Minutes## Showing the Time

There are two main ways to show the time: "24 Hour Clock" or "AM/PM":24 Hour Clock:the time is shown as how many hours and minutes since midnight.AM/PM(or "12 Hour Clock"): the day is split into:AMhours), andPMhours).Like this (24-hour above and AM/PM below it):

AMPMAnteMeridiem*Latin for "before midday"PostMeridiem*Latin for "after midday"*Is that spelled "Meridiem" or "Meridian"? See here.## Converting AM/PM to 24 Hour Clock

For the first hour of the day (12 Midnight to 12:59 AM), subtract 12 HoursExamples: 12 Midnight = 0:00, 12:35 AM = 0:35

From 1:00 AM to 12:59 PM, no change

Examples: 11:20 AM = 11:20, 12:30 PM = 12:30

From 1:00 PM to 11:59 PM, add 12 Hours

Examples: 4:45 PM = 16:45, 11:50 PM = 23:50

## Converting 24 Hour Clock to AM/PM

For the first hour of the day (0:00 to 0:59), add 12 Hours, make it "AM"Examples: 0:10 = 12:10 AM, 0:40 = 12:40 AM

From 1:00 to 11:59, just make it "AM"

Examples: 1:15 = 1:15 AM, 11:25 = 11:25 AM

From 12:00 to 12:59, just make it "PM"

Examples: 12:10 = 12:10 PM, 12:55 = 12:55 PM

From 13:00 to 23:59, subtract 12 Hours, make it "PM"

Examples: 14:55 = 2:55 PM, 23:30 = 11:30 PM

## HOLIDAY HOMEWORK - INVESTIGATE MEASUREMENT (use youtube, google, our wiki - under measurement etc.)

1. What equipment can be used to measure with?

2. Perimeter, Area and Volume - What are they?

3. 24 hour time, analogue clocks: Can you read an analogue clock? Can you tell 24 hour time?

4. Find examples of Timetables and maps (Eg: bus or train timetable)
