#### Spot The Mistakes - Percentages

(24)
This is a twist on revision notes. I have written some notes and given examples but there are mistakes that the students have to correct. They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into two bits but I have included the whole thing so that you can chop them up your own way, or change stuff if you want. It's a bit of an experiment and we&'ll see how it goes!

They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into three but I have included the whole thing so that you can chop them up your own way, or change stuff if you want.

#### Adding and Subtracting Fractions Codebreakers

(31)
The usual joke to find the punchline for but two sheets: sheet one is relatively easy whereas sheet two is all mixed numbers. Corrections made to codebreaker 1 - thank you for spotting them for me!

#### Spot The Mistakes - Expressions and Equations

(6)
This is a revision aid where students must read the 'notes' carefully and find the deliberate errors (and possibly undeliberate ones!). I have split (with some overlap) it up into three parts going from 'what is an expression/identity/equation?', through simplifying, expanding brackets, factorising into a bracket, solving equations, multiplying out 2 brackets, factorising quadratics and solving quadratics (factorising, completing the square and the formula). The aim is to get them active in their revision!

#### Year 12 A Level Pure Maths Powerpoint

(0)
This 500+ slide Powerpoint covers all of the first year of the single A Level Pure course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. I used this during the first year of the new course.

This 270 slide Powerpoint covers all of the first year of the single A Level Applied course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. Colleagues of mine used this during the first year of the new course.

#### Erica's Errors On Algebraic Expressions

(9)
Erica is taking A level mathematics but is making silly errors in her homework. Can your students spot and correct the errors, explaining what Erica has done wrong. These are designed to create discussion and reinforce understanding of the topics. This is thefirst A level version of &quot;Clumsy Clive&quot; which covers the GCSE curriculum.

#### Erica's Errors On Algebraic Methods

(4)
Erica is struggling with algebraic division, the factor theorem and proof. She needs your help to correct her mistakes before explaining what she's done incorrectly. This is designed to create discussion and embrace the new curriculum that likes getting students to spot mistakes.

#### Completing the Square and Their Graphs

(1)
Eight quadratic functions to complete the square (including one where the coefficient of &quot;x squared&quot; is not 1) for students to do then plot the graphs. The aim is for them to spot how completing the square informs transformations of functions.

#### Pythagoras Matching

(1)
Four matchings getting increasingly difficult at they go Firstly spot the correct formula for the correct triangle, the next two calculate a missing side and finally use Pythagoras to find the area of a shape. These have been designed to be used as starters or plenaries but you could use them as a main lesson activity; up to you.

#### Ludwig von Terrible Mission -Activity & Worksheets

(11)
A KS3 resource activity with worksheets to be completed by students. This was an idea I had that actually came to fruition - it's based around a secret agent type mission. It involves deciphering codes, grid references, bearings, simplifying algebra, ordering fractions and sequences. I did a silly video to introduce it using some of my daughter's puppets. Hope you enjoy it, my classes certainly did.
