Hi I was wondering if someone out there could help me. I need to teach a mixed ability class of y6 pupils this objective: Solve simple problems involving direct proportion by scaling quantities up or down.' Problem is I teach LA maths and we have only just barely touched ratio, let alone applied it to problem solving so am feeling a bit confused! The more I think about it the more of a muddle I am getting in! Am I right in thinking that direct proportion means to scale up or down following a given ratio? ie, if there were 3 girls to every 2 boys (3:2) the by using direct proportion to scale up then there would be 6:4, and if I had 8 boys then I would have 12 girls (12:8)? Am I right??? Does it matter which way round the numbers go? I need to get this sorted, as then once I know the basis of what I am actually doing then I can plan a lesson to suit (if anyone has any good ideas please share!) I really want this job, but am getting in such a muddle with everything getting on top of me at the moment. I've not applied for a job for 5 years so am surprised to get an interview from the first one TBH!
