#### Algebraic Proof

(39)
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

(14)
The worksheet teases out expressions to show certain situations (e.g. the sum of 2 consecutive odd numbers) and features options on an &quot;answer grid&quot; 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)

(38)
This workbook provides excellent opportunities for improving algebra skills while learning how to construct an algebraic proof. Click 👉 tes.com/…/Workbooks… to download workbooks on other topics.&lt;hr&gt;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.&lt;hr&gt; Note that the booklet is designed to be printed as A4, but I usually reduce it to A5 and it still does the job.&lt;hr&gt;👍If you like this resource, then please rate it and/or leave a comment💬.

#### Proof for A-level Maths

(28)
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.

#### Vector Proof

(7)
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 https://prezi.com/lenmenrpi1li/vector-proof/

#### Proof that √2 is Irrational

(7)
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.

#### Circle Theorems: Explaining their existence (proofs)

(6)
In this resource, I go into detail about why Circle Theorems are actually true; not just taking them at face value. The aim is to enhance students’ understanding of not only the Theorems, but to introduce them to the idea of rigorously proving statements in mathematics. Please feel free to review my resource. Hope this helps, A_Maths.
