Maths app for grade 2: keeping track of where the class stands
Which maths app for grade 2 shows the teacher where the class stands, which topics matter in grade 2 and how the overview helps in lessons.
In brief: For grade 2, a maths app is worth using if it shows you after practice which topics are secure and where the class is getting stuck, without you having to write your own test. Make sure the overview is organised by topics such as bridging ten, times tables, money and telling the time, and that it makes typical errors in thinking visible. In Mazio Maths, “Results” shows where the class stands in the five content areas, how each unit went and which misconceptions are appearing in the class.
This article is for teachers of a grade 2 class who are looking for an app for lessons and want to know what the children can already do. It names the important topics of grade 2, describes what a good overview for teachers should provide and shows what this looks like in Mazio Maths.
What grade 2 covers
The curricula of the German federal states usually combine grades 1 and 2. The Bavarian mathematics curriculum for grades 1/2 includes, among other things, calculating with numbers up to 100, the core facts of the times tables, working out amounts of money in euros and cents, telling the time and measuring lengths. The German national education standards (KMK) organise everything into five content areas: numbers and operations, quantities and measuring, space and shape, data, frequency and probability, and patterns, structures and functional relationships.
For an overview in an app, this means it should show how things are going in these topics, and especially where children typically get stuck.
| Topic in grade 2 | Typical error in thinking | What an overview should show |
|---|---|---|
| Addition and subtraction bridging ten | For 52 − 7, the child calculates 7 − 2, result 55 | Whether the error occurs frequently and in which tasks |
| Times tables | For 5 · 3, the child calculates 5 + 3 | Whether the basic idea of “equal groups” holds |
| Place value | Twenty-three is written as 32 | Whether tens and ones are being mixed up |
| Money | Five 10-cent coins are taken to be more than one euro | Whether coins are counted instead of their values being added |
| Lengths | Measuring starts from 1 instead of from zero | Whether reading the ruler is secure |

What an overview for teachers should provide
A simple count of right and wrong answers is of limited help for planning lessons. These features are more useful:
- Organised by topic. You see which content the class has worked on and how it went there, instead of a single percentage.
- Errors in thinking, beyond error counts. A good overview shows whether the same pattern lies behind many wrong answers.
- No extra test. The evaluation builds up during practice in lessons.
- With a next step. The overview should make it clear what the class should practise next.
- Data-minimising. Children log in without an email address, and only the class’s own teacher sees learning progress.
A comparison of different providers against these criteria is in the article Maths apps with a teacher overview compared (in German).
How Mazio Maths shows where your grade 2 class stands
Mazio Maths is a learning platform for maths lessons in primary school. For grade 2 there are units in all five content areas, such as “Calculating in the hundred square”, “The dot grid” or “Frequencies: counting and representing”. The Basiscamp practises in the worlds “Numbers to 100”, “Addition and subtraction to 100” and “Multiplication and division”, with sections such as “Tens and ones”, “Bridging ten” and “Equal groups”. The difficulty adapts to each child’s previous work, even when the whole class is working on the same unit.
In the lesson. Under “Lessons”, you use the plus button to put a unit on your class’s board, and the children see it on their devices straight away. Each row of the board shows how many children have finished the content, for example “12/24”. Under “Live”, you start the lesson and see what the children are working on at that moment.
After the lesson, under “Results”. You choose the class and see what was practised, where the class stands in the five content areas, how each unit went and which misconceptions are appearing in the class. For every unit worked on there is an evaluation per level with the views “Overview”, “Heatmap”, “Training” and “Children”. The Knobelbox shows which task types are running above or below expectations, and the Basiscamp shows how many tasks were solved at the first attempt. The children appear with their code. If you have entered names, you only see them after unlocking with your teacher PIN.
The class overview. It shows how the class is distributed across expectation bands. You switch it on yourself for each class. The bands are based on fixed thresholds that apply equally in every class, and only a child’s own results count. Children only see their own progress.
Errors in thinking in the class. Once a week, Mazio Maths checks whether a misconception is showing up in the class, for example “When bridging ten, the carry is forgotten”. The support card explains the error with an example, lists steps for you under “In the classroom” and suggests units and Knobelbox tasks under “Matching content for the board”.
An example from grade 2. After two weeks of times tables, the evaluation of the unit shows that the class found one level difficult. At the bottom of the class overview, the teacher taps “View suggestions”. Each card gives a reason. The teacher chooses the Basiscamp sub-world “Equal groups”, sets “VISIBLE UNTIL” to “This week (Fri)” and puts it on the board. Beforehand, the class works with counters on multiplication tasks as groups. The teacher decides what goes on the board.
Next step. Topics, stumbling blocks and suitable content are on the page Mathematics in grades 1 and 2 (in German), and there is more on the times tables on the times tables topic page (in German). Register for free, create a class and print the access cards. Using Mazio Maths with a class, trying it out and licensing it is currently available to schools in Germany. If your school is in another country, registration records your interest.
Frequently asked questions
What does Mazio Maths show about my class?
Under “Results”, you see where the class stands in the five content areas, how each unit went and which misconceptions are appearing in the class. The class overview shows how the class is distributed across expectation bands; you switch it on yourself for each class. Login times and working times of individual children are not shown.
Which topics should a maths app for grade 2 cover?
At least calculating up to 100 with bridging ten, the times tables and measures such as money, time and length. In addition, there are shapes, patterns and simple data. Which content is taught when is set by your curriculum.
How is the overview of the class created?
The evaluation builds up while the children practise in lessons. No additional testing time is needed for this.
