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.
