Types of numbers – key words lesson

January 5, 2014

Here’s a lesson I’m using with a top set year 9 class. We’ll be in a computer room and we’re due to do module 9 (Types of numbers) from the Edexcel linear course. I’ve included some extra words but chosen not to focus on standard form in this lesson. The idea is that they’ll have a resource they can keep and pull out when they come to revise in year 11.

Here’s the email I’ll send to set up the lesson:

Hello and Happy New Year.

What could be better than having the first lesson of a new year as maths eh?

 Here are a list of maths words you’re expected to know about. They’re all to do with types of numbers.

You have about 35 minutes to create a single page of notes about them. I’d encourage the use of Publisher.

 [Diagrams are encouraged. Not too much text. Not excessive use of fancy colours/fonts.]

 After the time’s up, there will be a test.

  •  Factor
  • Common Factor
  • Multiple
  • Prime
  • Composite
  • Negative
  • Positive
  • Integer
  • Triangle Number
  • Square Number
  • Square Root
  • Cube Number
  • Cube Root
  • Index Notation
  • Rational
  • Irrational 


If anyone comprehensively finishes early, I’ll point them in the direction of Goldbach’s conjecture to see what they can find out about it.

I’ve made a quiz using socrative. If you’ve not had a go with it (and have access to computers or tablets or mobiles) I’d recommend trying it out. The students particularly like the space race option.

The quiz number for this topic is SOC-2832805 if you’d like to give it  a go.
