What is Mazio Math? A maths platform for primary school lessons
Mazio Math is a learning platform for maths lessons in primary school. What children practise there, what teachers see and who provides it.
In brief: Mazio Math is a learning platform for maths lessons in primary school. Children practise in the browser or in the app in three areas (units, Basiscamp and Knobelbox), and the teacher puts content for the class on the board and sees in the results where the class stands. The provider is MatheZeit UG (haftungsbeschränkt). Mazio Math is free for teachers; the school licenses its use with the children.
This page is for teachers and school leaders who have heard the name Mazio Math and would like to know what lies behind it. It describes what the children get, what the teacher does with it, who provides it and what it is designed for. As of November 2026.
Mazio Math, units and what the terms mean
“Mazio Math” is the name of a platform. Within the platform, the individual learning paths are called “units”. A unit builds up a topic step by step, from several stations each with many tasks, from first discovery to secure mastery.
| Term | What it means |
|---|---|
| Mazio Math | The learning platform for maths lessons in primary school, in the browser and as an app for iOS and Android |
| Units | Learning paths on a topic, such as “Calculating in the hundred square” or “Parallel and perpendicular” |
| Basiscamp | Exercises that build calculation skills, from number sense and place value to the written methods |
| Knobelbox | Short tasks for mathematical problem solving from all five content areas, from sudoku to combinatorics |
| Mazio | The learning assistant that helps directly within the task after a mistake, with questions, markings in the picture and partial steps |
| Board | What the teacher puts out for the class; the children see it first in their learning area |
The content is organised by the five content areas of the German national education standards: numbers and operations; space and shape; quantities and measuring; patterns and structures; and data, frequency and probability. It is designed for the two-year bands of grades 1/2 and 3/4. The teacher decides which content is used in which grade. There are units for grade 1 as well. The pages Maths in grades 1 and 2 (in German) and Maths in grades 3 and 4 (in German) show what is available for each two-year band.
What children do in Mazio Math
The tasks are interactive. Children reflect shapes, find rectangles or read diagrams directly on the tablet. Each unit is set in its own world with places, characters and a cover. Every task has variants at several levels of difficulty and feedback that matches the answer given.
The difficulty adapts to each child’s previous work, even when the whole class is working on the same unit. Alongside the correct answer, it also takes into account which mistakes a child makes. As a result, as a rule no two children work on exactly the same tasks, and the teacher does not have to prepare separate material for each ability group.
If a child makes a mistake, the learning assistant Mazio helps directly within the task. He responds to the answer given, names typical errors in thinking in simple words and asks a question. In the units, Mazio also shows the help in the picture. He marks the crucial spot, highlights part of the representation, hides a wrong answer option or fills in a simple partial step, so that the child solves the rest on their own. In the Knobelbox and the Basiscamp, he offers answers to tap in response to his question. He does not give the solution.
Each child logs in with their own eight-character access code or their access card. The children need neither an account nor an email address. Mazio Math is free of advertising, in-app purchases and chats between users.
How teachers work with Mazio Math
The routine in class is short. Under “Lessons”, the teacher uses the plus button to put a unit on the class board, and the children see it immediately on their devices. New content is placed on the board as compulsory, and with a note the teacher gives the children a sentence to go with it, such as “Afterwards you can go to the Knobelbox”. Each row of the board shows how many children have finished the content, for example “12/24”.
Under “Live”, the teacher starts the lesson and sees what the children are working on. When the teacher watches a child, the child sees an orange frame with the message “Your teacher is watching right now”. This lets the teacher see where a child needs help at that moment.
After the lesson, “Results” shows what the class has practised, where it stands in the five content areas and how each unit went. Once a week, Mazio Math checks whether a misconception is showing up in the class, and the support card suggests steps for teaching and suitable content for the board. Mazio Math recognises a pattern and suggests suitable exercises. The teacher decides what goes on the board.
An example from the classroom. At the start of the week, a grade 3 teacher puts the unit “Number walls: multiplication” on the board as compulsory and adds the note “Afterwards you can go to the Knobelbox”. On Thursday the row shows “19/23”. In the results, the teacher sees which levels the class found difficult and uses “View suggestions” to add a matching Knobelbox set. A teacher in the scientific study describes everyday practice like this: “All the children get an iPad, we briefly discuss today’s topic and any information they need, and then the children log in and work. First the unit I have pinned, then they are allowed to play the Knobelbox and duels.”
Who provides Mazio Math
The provider is MatheZeit UG (haftungsbeschränkt). Mazio Math was developed from mathematics education research. Learning paths and tasks are created by a team from maths education, design and software; new tasks are trialled and evaluated in test classes and checked before release. Mazio Math is an independent offering. Teachers register directly on the Mazio Math website and do not need access through an education authority or a government learning platform. Mazio Math is in use in regular lessons at several hundred schools and was tested in a randomised controlled study at primary schools in Germany. The article on the provider and funding of Mazio Math describes the provider, its origins and its funding.
