This simulation allows you to generate calculation problems for a wide range of physics calculations tailored to English KS3 and GCSE levels, but widely suitable for ages 11-16. The calculations are available in 5 difficulty settings, and full workings are shown as needed.

1. Select calculation:
   • Choose a calculation type from the drop-down menu.
   • Click the Filter button to search calculations by keyword and curriculum and narrow down your options.
   • Toggle Random mode to On to be given a series of random calculations to tackle.
     • Click on the drop-down menu to bring up the selection window, then toggle the check boxes to add or remove calculations from the random generation.
     • Use the Select all and Deselect all buttons to quickly adjust your selections.
2. Generate calculation:
   • Click Next to generate a question of this type.
   • Click Previous to view a previously displayed question.
   • Click Create button to generate a worksheet. In the window that appears:
     • Click Question types to choose how many of each question type you wish to include, you can have a maximum of 100 questions in total on the worksheet.
     • Choose the settings for your worksheet:
       • Give it a title in the Worksheet title box.
       • Toggle the Question arrangement button between By type to group questions by type, or Random to randomly arrange them, which encourages formula selection.
       • Toggle Include answers on to show the answers at the end of the worksheet.
       • Toggle the Question difficulty levels to select the difficulty of the questions, you can choose multiple levels.
       • Toggle Space for name on to give somewhere for students' names.
       • Toggle Include space for answers on to give space for students to write on the sheet.
     • Generate the worksheet:
       • Click Preview to generate the worksheet and see a preview of it.
       • Click Regenerate to make a new set of questions, useful if you have changed any settings.
       • Click Download PDF to download the worksheet as a PDF.
       • Click Download RTF to download the worksheet as an editable Rich Text File.
3. Show workings:
   • Toggle Show scaffold to show or hide the scaffolding that supports students through the problem.
   • When Show scaffold is set to Show, click any scaffold item to display that particular line of working.
   • Click Next step and Previous step to move through the working, or click Answer to display the final answer and all workings immediately.
   • Toggle Show formula list on to display a list of all the formulas that students can select from.
4. Adjust difficulty:
   • Use the difficulty slider to adjust the question difficulty from level 1 to level 5.
   • Level 1: Standard equation, integer values, no unit conversions or rounding.
   • Level 2: Standard equation, decimal values, no unit conversions or rounding.
   • Level 3: Either a rearrangement or unit conversion required, decimal values, no rounding.
   • Level 4: Rearrangements, unit conversions and rounding are likely.
   • Level 5: Rearrangements with more advanced conversions and more difficult rounding are likely required.

   Note: Level 5 often produces fairly wild-looking calculations. This is intended to test students' maths and can go well beyond what they might face in an exam.

   • At level 3 or above, use Equation subject to choose which quantity the question asks for, or leave it on Random.
