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!

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!

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.
