Algebraic Proof

A lesson that was used to secure a job. Lesson begins with testing students ability to expand double brackets. Presentation slides scaffolds working out needed for algebraic proof. This is complimented by a matching activity which is followed by a RAG activity, the red having a scaffold to assist students. Please leave feedback and rate!

Algebraic Proof - Expressions and Proofs

The worksheet teases out expressions to show certain situations (e.g. the sum of 2 consecutive odd numbers) and features options on an "answer grid" at the bottom of the page. The Very bottom of the sheet allows pupils to apply their new skills by attempting some proof work. Please feel free to adapt/modify for your groups and let me know how it goes! Thanks, James

Algebraic Proof (Workbook with Solutions)

This workbook provides excellent opportunities for improving algebra skills while learning how to construct an algebraic proof. Click 👉…/Workbooks… to download workbooks on other topics.<hr>The questions require the expansion of brackets, simplifying expressions and factorising. For this reason, this workbook can be extremely helpful to Foundations students as well as Higher. The first few exercises give practice at mastering the basics, then there are some nice challenging extension questions.<hr> Note that the booklet is designed to be printed as A4, but I usually reduce it to A5 and it still does the job.<hr>👍If you like this resource, then please rate it and/or leave a comment💬.

Proof for A-level MathsQuick View

Proof for A-level Maths

A PowerPoint covering the Proof section of the new A-level (both years). It includes disproof by counterexample, proof by deduction, proof by exhaustion and proof by contradiction, with examples for each. The proof by deduction section also includes a few practice questions, with solutions in a separate file. The final slide lists a few suggested sources of further examples and questions on this topic. PowerPoint slideshow version also included - suitable for upload to a VLE. Latest version posted 2/12/19 with a small correction to proof of the infinity of primes.
Algebraic Proof Maths ActivityQuick View

Algebraic Proof Maths Activity

Maths investigation suitable for KS3 and KS4. Using algebra to prove number facts. Print out the powerpoint slides to use as revision cards for algebraic proof. Alternatively use them as a teacher resource. The worksheet has six questions with worked solutions.
Vector ProofQuick View

Vector Proof

Linked to the defining vectors activity, using the vectors defined in the image to prove standard results like ratios of line segments, whether points lie on straight lines, etc. For extra challenge take out the image with the pre-defined vectors and add the image from my vector definition activity so that pupils have to define the vectors before using them. Answers can be found on the prezi at link
Circle Theorems ProofQuick View

Circle Theorems Proof

Use the word documents as a follow-on activity which requires students to think about how to prove the circle theorems. Cut each one up and ask students to put it in order. And the powerpoint just supports the order.

Algebraic Proofs

Structured Word document which leads through simple proofs through factorising, onto expanding quadratics, subtracting quadratics, and then harder proof questions. Exam questions are available at the end as well. Used with Set 2 Year 10.

Algebraic proof revision

A worksheet on the different types of algebraic proof questions on the Edexcel GCSE exams. I am getting to the stage with my year 11s that they need to be revising individualised topics rather than me teaching the whole class. I have designed this for them to work independently, without relying on my help. It contains examples and practice questions. Answers included. I hope this is useful! Please look at my other revision resources.

Angles in a Triangle Proof

Lesson on angles in a triangle proof, created in connection to my school's new scheme of work based upon the new National Curriculum.
Proof that √2 is IrrationalQuick View

Proof that √2 is Irrational

This power point provides you with a guide as to how we know v2 is irrational. Works well for KS4 and KS5 students as I find that many of them are not content with just being told that surds are non-recurring, non-terminating. You will need to present this to students - they're unlikely to follow it by themselves.
