#### Spot The Mistakes - Fractions

(33)
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 three 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!

#### Foundation Revision - Spot the mistakes - 24 questions

I have made this to provide a spin on the revision process leading up to the GCSEs. I have created 24 exam-style questions and have provided some 'working out' and an answer. All of the answers are incorrect by means of a common misconception. The task for the pupils is to spot the mistake and correct it. I have tried this with multiple classes and they find it fun and useful and many of them fail to spot the misconceptions thereby promoting some insightful discussions too.

#### Simplify ratio tarsia spot 7 mistakes

(0)
A diamond shape tarsia (jigsaw) where I have deliberately made 7 mistakes for the students to find. I snipped the solution tarsia and pasted it onto powerpoint or word to circle the wrong answers. You could just print it and highlight the wrong answers if you prefer. Students love to try and prove us teachers wrong and I have found this activity goes down a treat. I make sure they write the question down and then simplify it themselves to show if the answer is right or wrong, then label it on the printed out tarsia. Make sure you don't print out the output like you would usually - it's the solution you want!
