Educational calculation tool rather than "question".

This allows the student to input a square matrix (max rows 5). Then the student can decide to swap some rows, or multiply some rows, or add multiples of one row to other rows. The student only has to input what operation should be performed, and this is automatically applied to the matrix and the identity matrix (or what it has got to). This question has no marks and no feedback as it's just meant as a "calculator". It has some checks in so students know when they are not entering a square matrix or a valid row number etc.

It has some rounding to 13 decimal places, as otherwise some fraction calculations become incorrectly displayed as a very small number instead of 0.

It would be possible to extend to more than 5 rows, one just has to put in a lot more variables and so on. I just had to choose some place to stop.

This allows the student to input a linear system in augmented matrix form (max rows 5, but any number of variables). Then the student can decide to swap some rows, or multiply some rows, or add multiples of one row to other rows. The student only has to input what operation should be performed, and this is automatically applied to the system. This question has no marks and no feedback as it's just meant as a "calculator".

Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. Two people walk away from a central flagpole, in different directions. The multiple choice question asks for the angle between them. There are seven potential scenarios.

Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. The bus timetable is shown, and one multiple choice question asked. There are seven potential questions (scenarios).

Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. A nutrition label is shown, and one multiple choice question asked. There are seven potential questions (scenarios).

Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. A diagram of a granny flat is shown, and one multiple choice question asked. There are six potential questions (scenarios).

Simple multiplication including multiples of 10, with answer that can be multiples of up to 1000.

Multiple choice question. Given a randomised polynomial select the possible ways of writing the domain of the function.

This allows the student to input a linear system in augmented matrix form (max rows 5, but any number of variables). Then the student can decide to swap some rows, or multiply some rows, or add multiples of one row to other rows. The student only has to input what operation should be performed, and this is automatically applied to the system. This question has no marks and no feedback as it's just meant as a "calculator".

Checking whether a given set is a plane or not. Depends on whether two vectors are parallel or not. Then checking whether the plane goes through the origin. This is not always obvious from the presentation.

Not randomised because it's the same as in our workbook.

Demonstrates how to set up a "choose one from a list" part where the number of choices is randomised.

The part is given a list of labels for the choices as well as a list specifying the marks to award for each choice.

Use the CSS preamble to give a bit more space between multiple choice answers.

Using a shuffled list variable to randomise the order of all options in a multiple choice part except the last one.

Do not use this: alternative answers are the best way of accepting multiple correct answers.

To assess interpretation of a statistical software output and use corresponding equation to make prediction.

Some simple multiple choice questions on the field of complex numbers.

This shows how to use captured groups in a mathematical expression part's pattern restriction to mark an answer involving multiple occurrences of an undefined function.

A demonstration of how to use the "variable list of choices" option for a "choose one from a list" part to shuffle only some of the choices, and always have the same "I don't know" choice at the end of the list.
