Simplifying Ratios

The start of the lesson is used to review matching simple proportions with their corresponding diagrams.  The development phase builds on this by introducing ratios using diagrams.  As learning progresses students begin to simplify a ratio by calculating the highest common factor.  The plenary consolidates the learning by matching up equivalent ratios to find the odd one out.
Differentiated Learning Objectives
  • All students should be able to simplify a ratio using common factors.
  • Most students should be able to fully simplify a ratio using the highest common factor.
  • Some students should be able to calculate equivalent ratios involving multiple different units.

Mathematics OFSTED Inspection – The Deep Dive

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question.

How Write 3 Part Ratios

When learning how to write 3-part ratios students need to understand how ratios can be made equivalent. The start of the lesson reminds students by asking which of six ratios is the odd one out.  This is presented to the class as they come into the lesson.    Writing Equivalent Ratios  A few students immediately go […]
