A staged problem-solving activity on the unitary method for proportional reasoning. The resource provides a card sort for the first two questions, step by step instructions for a further 3 questions and finally no structure for pupils to work independently through the remainder of the problems.

Useful for KS4 revision but could also be used at KS3.

Hi Claire,
Thank you for letting us know about this. We have now fixed it and checked the rest of the resource.

There are two errors on slide 2. The question states find the maximum number of songs, the support states the minimum. The answer is also wrong, they can only buy 31 not 32. Bit worrying that I will need to check all answers before using.
