Create / Edit a New Task

You can create your own mathematical tasks in the MathCityMap web portal. Here is a step-by-step guide on how to create and edit new tasks:

Step 1 – Open the task area

To create your own task, click on the “Tasks – Create and manage” field.

You can also click on “Tasks” in the menu bar on the left-hand side.

There is a plus symbol at the top left. Click on “New task” to start creating your task. The task will not be saved automatically, so don’t forget to click on “Create” after entering the information.

Step 2 – Enter basic information for the task

You will now be asked to enter the basic information for your task.

Cover picture: Upload a picture of the place where your task is located. It’s easiest to use the QR Code. Scan it with the smartphone that you took the picture with and follow the instructions. Make sure that the task cannot be solved by the cover image alone.

Basic data: Choose a suitable title for your task. Write down a precise definition of the task and provide all the necessary information.

Position: To indicate the exact position of the task, simply click on the right spot on the map.

Step 3 – Answer format and solution

Various task types can be selected in the bar. Decide which format makes sense for your task.

For example, if you want to determine an exact number, it makes sense to ask for an exact value. With measurement tasks, small measurement errors can occur, so it makes sense to offer a solution interval here. Depending on the type of task, different solutions must be given.

Then provide a sample solution to your task. This can be in written form or as a picture.

Step 4 – Stepped hints

Up to three hints can be given for a task. These can be helpful in solving the task.

They can contain an idea or an approach to a solution or even a concrete formula or direct instructions.

To do this, select the hint type and then add a text, image or video.

Step 5 – Task meta data

Interesting information about the object of the task can be added here. For example, you can enter the year of construction of a building or exhibition information about a sculpture.

You can also specify the grade level for which the task is suitable. This is particularly important for public tasks so that MCM users know whether the task corresponds to their mathematical abilities.  

Furthermore, the required tools can be specified here, such as a folding ruler or measuring tape.

Finally, you should define certain keywords. These also help other MCM users to decide whether they want to solve the task or not. To do this, enter a term and confirm it by pressing the Enter key.

Your own name is automatically entered as the author. The e-mail address of the linked account is also listed there, but it is not visible to others. Finally, click on “Create” and your task is created in the web portal.

Step 6 – Edit tasks

f you want to edit your task later, go to “My tasks” via the “Tasks – Create and manage” field.

Select the task you want to edit. You will then see an edit icon at the top right. If you click on it, you can adjust the cover image, basic data, position and meta data afterwards.

Click on “Save” at the bottom to save your changes.

Finding tasks outside

To find suitable mathematical tasks outside, you should look for certain objects in your environment that are well suited for mathematical questions. Here are some steps you can follow when looking for suitable objects and questions:

Step 1 – Recognize suitable objects

Look for objects with clear geometric shapes or fixed dimensions, such as rectangular buildings, round fountains or linear paths.

You can also use natural features such as trees, plants or hills.

Road signs, distance markers or other markings in the environment also often provide valuable data for mathematical questions.

Schritt 2 – Fragestellung

Make sure that your question also requires an activity. In order to solve the task, you have to estimate, observe or measure and also calculate.

You should therefore not choose objects where you can already read off the solution.

Search and filter public tasks

You can find public tasks that have already been created in the MathCityMap web portal. The search for suitable tasks can be narrowed down using various filters. Here you will find a step-by-step instruction on how to search for and filter public tasks in the web portal:

Portal

Step 1 – Accessing public tasks

To search for public tasks, click on the “Tasks – Create and manage” field.

You can also click on “Tasks” in the menu bar on the left-hand side.

A page with your tasks will open

Step 2 – Search for tasks

Click on “Public tasks” to search for specific math tasks that are publicly available.

The magnifying glass symbol allows you to enter keywords that should be in the title of the task.

Step 3 – Sorting tasks

The tasks can be sorted in ascending and descending order according to three different criteria: by creation date, by distance from the current location and by class level.

Step 4 – Filter tasks

There are various options for narrowing down the search using the filter symbol.

Grade level: select the grade level for which you want to find suitable tasks.

Period: select the period in which the task should have been created. 

Language: filter the tasks according to the availability of languages or activate the slider if the tasks should be in your own language (which is selected in the web portal).

Topic: If you are interested in a specific mathematical topic, you can enter it as a tag. This will only display tasks on this topic.

Task format: select which answer format your task should have.

Step 5 – View results and open tasks

The selected filters are displayed in a blue box above the tasks.

If you want to reset your filters, you can click on “Remove filters”.

After you have set the filters, the matching tasks will be displayed.

Click on a task from the list to see more details.
