Circle theorems

Circle theorems

A complete lesson on the theorem that the angle at the centre is twice the angle at the circumference. For me, this is definitely the first theorem to teach as it can be derived using ideas pupils have already covered. and then used to derive some of the other theorems. I will shortly be uploading lessons for the other theorems. Activities included: Starter: A few basic questions to check pupils can find missing angles in triangles. Main: A short discovery activity where pupils split the classic diagram for this theorem into isosceles triangles (see cover image). If you think this could overload pupils, it could be skipped, although I think if they can’t cope with this activity, they’re not ready for circle theorems! A link to the mathspad free tool for this topic. I hope mathspad don’t mind me putting this link - I will remove it if they do. A large set of mini-whiteboard questions for pupils to try. These have been designed with a variation element as well as non-examples, to really make sure pupils think about the features of the diagrams. A worksheet for pupils to consolidate independently, with two possible extension tasks: (1) pupils creating their own examples and non-examples, (2) pupils attempting a proof of the theorem. Plenary: A final set of six diagrams, where pupils have to decide if the theorem applies. Printable worksheets and answers included. Please review if you buy as any feedback is appreciated!

Maths: Lexicology Across the Curriculum - Bingo.

Maths: Lexicology Across the Curriculum - Bingo.

There are eight different bingo cards in this resource. I do not call out the affixes (prefixes and suffixes), I elicit the name of the affix through a series of concept questions. This is a great resource to improve knowledge and understanding of prefixes and suffixes which will ultimately develop a Mathematical Lexicon. Bingo as a ten minute starter creates a fantastic learning environment. For more resources visit my website www.lexicologyforreading.co.uk

Compound Area with Circles - Problem Solving

Compound Area with Circles - Problem Solving

This is a lesson developing on from area and circumference of circles, allowing students to apply the skills onto more complex shapes and incorporate into a problem solving question. Answers are on slides, as well as some examples and the complex problem at the end has a step by step. This is aimed at upper middle/higher ability students

Formula Revision Foundation

Formula Revision Foundation

A set of 6 simple formula recall tests. Foundation level. With answer slides. Along with these I made sets of cards with 4 questions on to practice using the formulae. I laminated these and let the pupils choose which one to do. Answers to these are also on the Formula Test and Answers files. The Formula Test And Answers notebook file has links to the various answer slides along with links to the original question cards. Question cards A to F are a mix of stuff. Question cards G to J are my first attempt at making some SSDD questions. I’ve been adding to it as I go along, so there may be more to come. I’ve exported the main Formula Test And Answers to pdf for those who don’t have access to Smart notebook - links don’t work on that though. If you see any errors please feel free to say in the comments.

Four fantastic investigations for higher end thinking.

Four fantastic investigations for higher end thinking.

This was done on my trip to the Science Museum. We took four key shots and have come up with four investigations in relation to these photos. They start very easy and become rather tricky. These are brilliant for those students who really need to be pushed at the higher end!
