Maths–Collecting Data

June 11, 2011

 

Favourite pony colours

In maths this week we going to create some entries for a competition. It is a competition about collecting and presenting information as a BIG poster.

You are going to research and present information on a topic. You will produce a poster that includes the following things:

An interesting Idea

An introduction

Information about how you collected the data

Graphs

Charts

A conclusion

‘A good poster will enable the reader to discover the story behind the data by following the logical progression of the poster. The emphasis is on the visual display of results through well placed graphs and a suitable commentary including an introduction and a conclusion.’

Here is some information about what a good poster does and doesn’t include.

Here are the rules.

Here are some examples of previous entries.

More information on the poster competition can be found here: http://www.spoc4schools.org/

You can leave a comment here to tell people what you have learnt about the properties of shape, or to leave any shape-based questions!

Here is some information about rotational symmetry:

Travelling Salesman Problem

February 19, 2011

Some of you requested a new maths challenge… This should keep you occupied!

The letters in the diagram represent towns.
The numbers show the distance between those town in km.

Imagine a travelling salesman has to visit all six towns, starting with C, travelling the shortest possible distance. (He doesn’t necessarily have to return to C when he has finished).

A. In what order would he have to visit the towns?
B. How far would the shortest distance be?

Leave your answers in the comments.


Homework

February 4, 2011

Attached is this week’s homework.

It is a maths homework – read it carefully as there are a couple of extra tasks!

Beware – think before you print it out. It’s got a lot of pages!

Have a great weekend.

Maths Targets

February 2, 2011

Our maths targets for this half term are based on multiplication at six different levels.

You choose the level level that best reflects what you need to do. You can work on these targets at school and at home.

You can print off your own copy here: Multiplication Target


Village Hall Problem Solving

January 27, 2011

As you know, The Village Hall has been our temporary classroom since we returned to school after Christmas on Tuesday 4th January. Today we carried out some problem solving to work out how far we have walked to the Village Hall.

Firstly, we measured the distance between the two locations. This was 225 metres.

We then worked out that we have been at the Village  Hall for 18 days. On most of these days we have made eight journeys – some days there have been less. Using this information we worked out that we had made approximately 116 individual journeys!

This makes a total of 26100 metres walked by each person (116 x 225m)

This is 26.1 kilometres! (26100 ÷ 1000) 

That’s the same as 16.22 miles each! (0.62137 x 26.1)

That is a lot of extra walking you have all done!


Co-ordinates Solution

January 8, 2011

A few weeks ago we completed this problem in maths:

Eight Hidden Squares

When we completed it we submitted our solution as there wasn’t one on the website. Well, they have now published our solution here, along with those from two other schools!

http://nrich.maths.org/6280&part=solution

Well done! (Yes, they have accidentally said ‘Year 4s’ instead of ‘Class 4′, but I’m sure we can forgive them!)


Decimals

January 8, 2011

We have been working with decimals this week.

These games involve ordering decimals:

Perimeter resources

November 2, 2010

Perimeter and area Game – This game has three levels.

Perimeter Explorer – more complex shapes.

Shape Surveyor – Find the perimeter of these shapes.

Perimeter of Rectangles – This gives you information about how to find the perimeter.

On Education City : The game High Rise and, for even more of a challenge, High Rise 2.

PERIMETER CHALLENGE – Numerically equal

I want to draw a square in which the perimeter is numerically equal to the area.

Red square.

Of course, the perimeter will be measured in units of length, for example, centimetres (cm) while the area will be measured in square units, for example, square centimetres (cm2).

Question 1: What size square will I need to draw?

Question 2: What about drawing a rectangle that is twice as long as it is wide which still has a perimeter numerically equal to its area?

Question 3: Can you find any more answers to Q1 and Q2?

Hint: Some squared paper may help.


Maths Challenge 3

November 1, 2010

Watching the Wheels Go ’round and ’round…

The front wheel on the penny-farthing bicycle has a circumference of 200 centimetres.

1. If you were describing the circumference in metres, what would it be?
2. How many times would the wheel turn if the bicycle travels one kilometre?
The back wheel on the cycle has a 50 centimetres circumference.
3. If you were describing this circumference in metres, what would it be?
4. How many times would this wheel turn if the bicycle travels one kilometre?
5. Would the large or the small tyre get more wear and tear on a long journey?

Maths Challenge 2

October 15, 2010

Tim’s class collected information about all their pets. They have six different kinds of pets between them.

This is the block graph they are making to show how many of each pet the class has altogether.

graph showing bars of 10, 4, 6, 1, 8 and 3

The children have not yet put in the animal names under each column. Can you do this for them using the information below?

There are two less cats than dogs.
Only one child has a parrot at home.
The number of fish added to the number of gerbils is equal to the number of dogs.
There are twice as many fish as hamsters.
There are half the number of gerbils as there are cats.

Give your answer in the comments – write the labels for the x axis in the correct order.


Weighing objects

October 8, 2010

 

Today we have been weighing objects and reading scales accurately.

These games will help you to practise reading values from scales:
