We are starting to see more and more questions at GCSE asking students to spot and correct the mistake made.
Clumsy Clive and Erica’s errors problems by @andylutwyche for are a perfect way to tackle this and I have edited and collated them togther.
“Erica has made some silly mistakes on her homework. Your students’ task is to find the errors, correct them and explain what Erica has done incorrectly. This should generate discussion in class.”

Goal free problems are GCSE questions without the question! Just the information.
This allows students to create and answer their own questions which is the highest ranking skill in Bloom’s taxonomy and means the task is instantly differentiated by students’ outcomes.
Enjoy!

These papers test skills that appear on foundation tier papers, aimed at students working at/towards grade 5.
Each set of these papers test 10 skills at GCSE level.
Each set has 4 versions to choose from with increasing levels of difficulty:
4 Green > 4 Yellow > 4 Red > 2 Blue
For example,
A green paper simultaneous equations question has the same coefficient of y.
A blue paper simultaneous equations question is worded with a contextual answer.
This allows you to build up students confidence and improve their skills at a pace appropriate for your class.
There are worked solutions to accompany every paper.
There is also a spreadsheet included for you to record your overall class scores and also question by question scores.

Here are my same surface different depth problems!
Lots of students don’t read questions carefully enough and just assume what the question is asking them to do based on the basic information in the question.
These problems aim to combat this.
Each page contains 4 problems that, on the surface, appear the same (or at least very similar!)
However each question requires different skills to solve.
This means students have to read the question very carefully to deduce which skill they should be using.
Enjoy!

Complete lesson on combining transformations.
Includes:
> Starter - run the powerpoint and it will animate all 4 transformations at once! Discuss with students which transformation each one is showing and congruence.
