Students should work independently 
Students should proudly show their workings out near the question.
Students can ask for help with reading a word.
Students can write an answer, even if they are not sure it is correct
Students can write these codes to the teacher - if they want to tell the teacher something
- CR = can't remember
- NL = never learned
- NH = need help
- NS = not sure
- NC = need calculator
If the student could work out the answer if they were allowed a calculator - they can write down the sum they would do.
independently means by yourself,
- an independent student won't ask for help
- an independent student won't copy another student
