These questions are to assess your understanding of using operations with decimals using the Numeracy Progressions (NSW DoE). This is an assessment. You can not use a calculator or ask for help. Using a calculator or asking for help may incorrectly show that you are able to complete operations, when you may need further support in order to be able to demonstrate that skill. If you don't know how to complete a question, you may leave it blank or have a guess.

You may wish to delete slides to adjust to student need.
