Year 9 have been looking at simplifying algebraic fractions. They have spent the last half term looking at Fractions, Decimals and Percentages and the last few weeks expanding and factorising expressions so I thought I showed them the following and then next lesson the series of TRUE or FALSE statements. I thought that this would be a good idea to help students understand why some fractions can be simplified and others can’t. I have wondered if it might be a good idea to use the “factors” slides in my next lesson on factors as and extension of the basic idea of 7 is a factor of 35 etc.
