• I love these starters. I have begun to make an index of some of the topics so I can refer to them when I want to have the starter match the main topic of the lesson. Do you have a printable index?
  Thanks

• Great starter. But we all found it VERY easy.... We wrote commas between every 3 digits to make it easier to read. What do others think about using commas?

• Good question King Alfred's College OXON. What do you think about using commas to separate the digits in large numbers? Traditionally it has been common to use commas to group digits into sets of three counting right to left. This however does not apply to the decimal part of a number possibly because all of those commas would detract from the decimal point. An alternative is to use a space instead of the comma and this technique can be used for the decimal part too. The digits would be grouped in sets of three counting from the decimal point outwards.
  Many European countries use a comma in place of the decimal point and use a full stop or blank space to separate every third digit.
  These conventions did not always work well with technology that was not set up to recognise the commas or spaces so in certain applications are not used. What rules do you promote to your class?
