# Sketch

Teachers can now also create *graphic* questions where students will have to sketch the corresponding answer. They will only have the handwriting tool available to do that, so the teachers can set a tolerance for slightly inaccurate answers. With this feature, students will be able to draw points, lines, circles, conic sections, and more, and the new evaluation criteria will do the rest!

## Sketch answer type

When the *Sketch* option is selected, the drawing tool replaces the equation editor. Using the upper toolbar, you may readily draw the correct answer to the question. Bear in mind students will use the handwriting mode to do so, for which you can see more details here.

It's also possible to include initial content for the students. It can be beneficial when, for instance, we want them to indicate some elements of a given object.

## Input options

In the *Input options* screen, you can control the offered auxiliary input.

### Answer input method

Here, you can choose what kind of additional entry you want to offer to the students.

There are three options:

**Display auxiliary CalcMe**: You can supply your students with our online calculator while answering the question and set initial content for the calculator if desired. Keep in mind that the calculator can do a lot more than numerical computations!**Display auxiliary text field**: You can provide your students with a text editor to make them include the reasoning they have followed to answer the question. For more details, see this page: Auxiliary input.**Don't show auxiliary input**: Don't show the additional CalcMe calculator nor the auxiliary text editor in the input field for the student's answer.

## Validation options

The validation options field allows to define us how we want to evaluate the student's answer. This section is divided into two sections explained below.

### Elements

The *Elements* subsection is thought to select the elements in answer to be evaluated. By default, all the elements that are not points will be taken into account, and they will have to match the student's answer to be graded correctly.

### Criteria

The *Criteria* subsection is thought to set the amount of error allowed between the student's answer and the correct answer. By default, is set to 1 as the minimal tolerance for slightly inaccurate answers.

## Example: Drawing a quadratic function

Imagine creating a question asking to draw using the handwriting mode the quadratic function $y=(x-2{)}^{2}-3$. To do so, we need to start defining the corresponding correct answer using the *Expression option*.

Then, we must define the validation properties we want to consider to grade the students' answers correctly. We will only validate the solution if the student's representation is close enough to the correct answer graph, so the amount of error allowed by default will be correct.

Finally, ee can preview the question by clicking the *Test this question* button. Thus, we can verify if it's working as we expected.
