Voting systems

Finding betting ways to vote

We looked at different ways to decide which candidate or choice won a vote. We realised that by using different methods, different candidates won the vote. This raises the troubling question about whether our way of voting is the best and the fairest. Here is a link to the activity we did and here is a link to an interactive website that discuss precisely this question. In the UK, the voting system is relative majority. However, it could be a good thing if we use absolute majority voting, because it would allow members of smaller parties to also get a voice. This could lead to a bigger number of parties rather than two or three major parties. However, there is no perfect voting system.

Gabriel’s problem

Gabriel box

Gabriel wrote the numbers 1-9 in a 3×3 grid.

He then multiplied together all the numbers in each row and wrote the resulting product next to that row.
He also multiplied the numbers in each
column together, and wrote the product
under that column.
He then rubbed out the numbers 1-9.

Can you work out where Gabriel placed the numbers 1-9?
