This is a whole lesson, and the second lesson building on the introduction to upper and lower bounds, which looked at finding the bounds of a single amount. 15 slides + handout + 2 worksheets. IMPROVED AND UPDATED!!
The lesson looks at more complicated area questions and other problems involving bounds, such as speed, distance and time. It has plenty of different examples with excellent teaching slides. It is appropriate for higher tier classes at GCSE as it involves the most challenging questions on this topic. If you are looking for the material only for foundation level or KS3 then lesson one is ideal. It also includes a handout summary to give to the pupils and exam questions for the most able in the class. I OFTEN teach this over two lessons and there is enough material provided to do so!
Both lessons on bounds include good starters, plenty of examples, lots of questions, a differentiated levelled worksheet with answers. Learning objectives, keywords and plenary. This is a very clear two lessons and has been very effective at teaching the full spectrum of questions that could up on this topic.
