Practical intro to Ratio

This is a SMART file based around ratio using practical demonstrations with blackcurrant squash. Can be done in one or more lessons.

Starter is basic simplifying fractions with extension question.

I then hand out a topic objective sheet which they fill in before we start.

Pupils then discuss where ratio is seen in real life and then we move on to demonstrating concentrates of blackcurrant to water. I always start with 1:0 and 0:1. As we work through I demonstrate on the board what the numbers mean until we find the best ratio (normally 1:4). Pupils then do an exercise on writing a ratio. Peer assess and then re-fill in first objective and use RAG cards to show where they are.

Pupils then look at equivalent ratios and cancelling using HCF and do a SA exercise before PA. Then pupils can progress on to dividing an amount. All contained in this SMART file. Lovely engaging lesson that is fun to teach - had it observed in 2 schools and received outstanding on both.
