Converting Fractions to Percentages

This is a good example from Khan Academy of turning a fraction into a decimal (he uses a long division method) and then a percentage:

Converting Fractions to Decimals

Converting Decimals to Percentages

Equivalent Fractions (Cancelling, finding the lowest terms)

When you are asked to show a fraction in it's lowest terms you can use this method.

The video below is from Khan Academy on the same topic:



This shows the relationship to factors really nicely:

Reading and writing numbers up to millions

Reading and writing whole numbers to tens of thousands

Rounding Whole Numbers

This will help you to round to the nearest 10, 100 and 1000.

Beware of rounding using this method in real life.  If you are planning to fuel your car, for example, then it would be a good idea to round up regardless.  I wouldn't want to be blamed for you running out of fuel!

Drawing - plan view to front elevation

I am doing some work with my class based on the Harry Potter movies.  We recently visited the Harry Potter Studios near Watford and are designing a brand new scene for one of the films.  the pupils need to use scale drawing techniques and work out how much material they need to build the set, costing the materials for the producer (me).

This video shows one way of taking a plan view (from above) and turning it into a front elevation (looking at it from directly in front).  You will have to pause it at the end to see the result as it jumps off quite quickly!
