What on earth does this mean?

'positive integer scaling problems and correspondence problems in which n objects are connected to m objects'?
A PoS from the new NC and simpler than it sounds...
‘Positive integer scaling problems’ are those problems that involve multiplying and dividing by scaling, so increasing or decreasing something a number of times bigger or smaller.

For example:
  • An adult eats 3 times as much as a child. If the child eats 4 maltesers, how many maltesers does the adult eat?
  • A square has sides of 12cm. If I draw a square with sides that are 4 times smaller, what will be the area of the square?
  • A car is 2 metres long. If I make a scale model that is 100 times smaller, how long will the model be?

This PoS is from Year 3, so simple scaling will do - use the length of a child's feet and a giant is 10 times bigger - how long is his foot etc.


'Correspondence problems’ look at all the possibilities when you have two variables.


  • If you had 4 different coloured hats and 3 different pairs of gloves, how many combinations would you have?
Basically 4x3 = 12 (a 4x3 matrix can be used to help solve this).

Keep the Giant context and it could be that the Giant has 8 different pairs of shoes and 4 different pairs of socks. He likes to have different combinations for every day of the month. Has he got enough shoes and socks?


Hope that helps. It might even lead  you onto a ‘Giant’ themed unit based on Raymond Briggs' brilliant Jim and the Beanstalk!
