We continued to refer to the summary of the topics in each Unit of Mathematics – National 4 and kept the focus on the first Unit test (Expressions & Formulae) the week beginning 16th September.
This week we completed the Statistics topic (again revision this time of S3 work), and the class reminded about Mean, Median and Modal values (a nonsense rhyme was provided to aid with memory of these) before comparing results between data sets. Next we covered constructing pie charts and calculating the angles required before having a refresher on how to calculate Probability.
We spent one period of revision and one period doing a Practice Assessment which was then taken away by the pupils to work on over the weekend in preparation for the Unit test on Monday.
