Cumulative frequency curves

Cumulative frequency

Click on the image to go to the interactive culmulative frequency curve.

Move the red dots around on the y-axis to change the frequencies - the cumulative frequency curve, the box and whisker plot and the histogram will change accordingly.

Grid for number stairs

Here is a Word document with a number grid on - as requested! Click on the link and then on the Word icon to download.

Number stairs coursework

It's coursework time!

With number stairs you have to 'investigate the relationship between the stair total and the position of the stair shape on the grid'. You can change the grid size and the step size - in fact to get good marks it's good to change all (but not at the same time!)

Here is the link to the on-line version

A set of different sized grids can be downloaded here.

Finger multiplication

A little late for the exams, but how about this for multiplication using your fingers: click here. [HT Jeannette Thomas]

Prisms

Remember:

• a prism is a three-dimensional shape with the same cross section all the way along it.
• a circular prims is called a cylinder
• a rectangular prism is called a cuboid
• the surface area of any prism is the area of the two ends plus the perimeter of the end x the length.
• the volume of a prism is the area of the end x its length
• the perimeter of a circle is caled the circumference (= pi x D)

Calculator paper revision suggestions

Looking at the non-calculator paper these topics didn't come up - so they may possibly come up on the calculator paper:

• Pie charts maths stuff
• Mean from tables youtube
• Scatter graphs - line of best fit and correlation bitesize
• Probability tree diagrams youtube
• Ratios
• Percentages s-cool
• Significant figures
• Straight line graphs - finding the equation of the line slideshare
• Plotting graphs maths stuff gcse.com
• Solving equations slideshare maths stuff
• Transposing equations (make x the subject)
• Area and perimeter (Don't forget to memorise the area and circumference of a circle youtube) youtube on area and another
• Surface area of 3D shapes - eg a cylinder or triangular prism you tube
• Parallel lines (X, Y , F and C angles) bitesize
• Bearings bitesize youtube
• Similar shapes bitesize
• Pythagoras (Add to find the hypotenuse [the longest side] ; subtract to find any other side) youtube
• Trigonometry (Don't forget SOH CAH TOA) maths stuff bitesize

The last two are almost certain to come up!
I'll try to update this list with some links to appropriate resources - so keep checking it.

A circle joke

What do you get when you take the sun and divide its circumference by its diameter?

A circle poem

Fiddle de dum, fiddle de dee,
A ring around the moon is pi times d;
But if a hole you want repaired,
The formula is pi r squared.
