Spot The Mistakes - Percentages

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.

Spot The Mistakes - Expressions and EquationsQuick View

Spot The Mistakes - Expressions and Equations

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!

Clumsy Clive On Pythagoras and Trigonometry

Clive has two homeworks to tackle but is making mistakes once again. The first homework involves right-angled triangles, the second a question in 3D and non-right-angled triangles. Spot the mistakes, correct them and then explain what Clive needs to do in the future.

Erica's Errors On Algebraic ExpressionsQuick View

Erica's Errors On Algebraic Expressions

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 "Clumsy Clive" which covers the GCSE curriculum.

Pythagoras MatchingQuick View

Pythagoras Matching

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.

Completing the Square and Their GraphsQuick View

Completing the Square and Their Graphs

Eight quadratic functions to complete the square (including one where the coefficient of "x squared" 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.

Ludwig von Terrible Mission -Activity & WorksheetsQuick View

Ludwig von Terrible Mission -Activity & Worksheets

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.
