This activity is designed for children to spot the errors made in answering each type of question. I find it works best giving children a copy between two (the one without the correct answers in black ink) and getting children to discuss with their partner. Tell them at the start that some questions have been answered correctly. Where they are answered correctly, some demonstrate fluency (ask children how) and others could have been solved with a more efficient method (ask children how).
There are three files: guidance on how to use them, children’s copy of the test (without the answers) and teacher copy with the answers.
