Ask a Rostock child what the hottest day at the beach in Warnemünde has ever been and you will get a guess, a story and probably a dare. Ask a computer and you get an exact answer from 79 years of weather records, plus a surprise about how records work. That is the kind of question our live coding classes in English start from. Mecklenburg-Vorpommern gives every pupil Informatik from grade 5; we help children aged 6 to 12 get there curious, confident and already building things.
Live lessons since 2020 · 10,000+ students around the world · a regular mentor, in English
Short version
Coding classes for kids in Rostock with Modern Age Coders are live online lessons, in English, for children from 6 to 12. The youngest solve puzzles and build Scratch games; from around 9 children write Python and answer real questions with real data. Each child has one regular mentor who matches their pace and accent, either in a batch of fifteen to twenty or one to one.
Starting points
Which first course suits a Rostock child?
A thinking course for the youngest, a short Scratch course for a quick win, and Python for children ready to type.
What is the hottest day ever measured in Warnemünde?
A record is the easiest program in the world to describe: remember the biggest number so far. It still has a trick in it.
The data
The Deutscher Wetterdienst runs a weather station called Rostock-Warnemünde, less than five metres above sea level, and publishes its daily readings as open data that anyone may reuse if they name the source (licence CC BY 4.0). We downloaded the file on 3 November 2026.
For children we kept one number per day: the highest temperature reached that day, from 1 January 1947 to 31 December 2025. That makes a file called warnemuende_max.csv with 28,855 rows and, as our check found, no missing days in that column.
Two questions
First: what was the hottest day of all, and how hot was the hottest day of the very first year?
Second, and harder: how many times was the record broken? Every year, the program asks whether that year's hottest day beat the record so far. If it did, it is a new record.
Version 1: the hottest day of every yearPython
import csv
hottest = {}
with open("warnemuende_max.csv", encoding="utf-8") as f:
for line in csv.DictReader(f):
year = line["datum"][:4]
t = float(line["tmax"])
if year not in hottest or t > hottest[year][0]:
hottest[year] = (t, line["datum"])
top = max(hottest, key=lambda y: hottest[y][0])
print("Years:", len(hottest))
print("Hottest day of all:", hottest[top][1], hottest[top][0], "C")
print("Hottest day of 1947:", hottest["1947"][1], hottest["1947"][0], "C")
It prints: Years: 79, Hottest day of all: 2022-07-20 38.4 C and Hottest day of 1947: 1947-06-29 35.0 C.
The hottest day in the file is 20 July 2022, at 38.4 degrees. And 1947, the very first year, already had 35.0 on 29 June. Now the record count. The program walks through the years in order, keeps the record in one variable called record, and writes down each year that beats it.
Version 2: put this under Version 1 to count recordsPython
record = None
broken = []
for year in sorted(hottest):
t = hottest[year][0]
if record is None or t > record:
record = t
broken.append((year, t))
print("Times the record was broken:", len(broken))
print(broken)
It prints: Times the record was broken: 3 and [('1947', 35.0), ('1992', 36.9), ('2022', 38.4)].
Only three records in 79 years, and one of them is 1947, which "breaks" the record simply by being first: there was nothing before it to beat. The next record took until 9 August 1992, at 36.9, and the one after that until 2022.
Here is the surprise children enjoy most. Change the starting year and the number of records changes, even though not one temperature changes. Start counting in 1948, and 1947's hot summer is out of the picture, so 1948, 1954, 1959, 1963, 1992 and 2022 all become records: six instead of three. Start in 1960 and you get four. A record always means "the biggest since we started counting", and the start is a choice somebody made.

Source of the temperatures: DWD Climate Data Center, station 04271 Rostock-Warnemünde, daily maximum air temperature (TXK) for 1947 to 2025, CC BY 4.0, file fetched on 3 November 2026. The code, the counts and the table were made by us. In 62 of the 79 years the hottest day reached at least 30 degrees. The DWD has no part in our classes.
Youngest, with paper. Roll a dice ten times and write the numbers in a row. Circle every number that is bigger than all the ones before it. How many circles? Roll again: is it the same?
Ages 8 to 10, Scratch. Make a variable called record that starts at 0. Ask for numbers one at a time, and make the cat cheer when a new record is set.
Ages 10 to 12, Python. Change Version 2 so it skips years before 1948, and check that you get six records.
Going further. Find the coldest day of each year instead and count record lows. Which start year gives the most records now, and why?
Rostock schools
When do Rostock children start Informatik at school?
In grade 5. Mecklenburg-Vorpommern teaches Informatik und Medienbildung at every school type from then on.
The KMK describes Grundschule outside Berlin and Brandenburg as grades 1 to 4, so a Rostock child is in Grundschule from about 6 to about 10. In grade 5 things change. The Gesellschaft für Informatik reports in its Informatik-Monitor 2026/27 that Mecklenburg-Vorpommern teaches the subject Informatik und Medienbildung at all school types in grades 5 to 10, at least one weekly hour in each of those years.

Compiled from KMK information on Grundschule and from the GI Informatik-Monitor 2026/27 (Mecklenburg-Vorpommern and Germany-wide), checked on 2 November 2026. The ages are typical ones.
Measured by the GI, the Land is in a group of three that already reach six compulsory Informatik hours, the medium-term target, and it reports that about half of the Land's Oberstufe pupils take the subject. Few Länder take computing this seriously. For a parent, the practical point is simple: the school will teach the subject from grade 5, and children who arrive having already built games and asked questions of real data usually enjoy it more and find it easier. We teach beside school, never instead of it.
Can a Rostock child follow a coding class in English?
Yes, and most families are surprised how quickly. Here is why.
We say it first
Our lessons are live and in English only; we have no German-speaking teachers. We would rather a family knows this before the free class than finds out during it.
Children copy, then speak
A young child hears "move ten steps" while watching a sprite move ten steps. After a few lessons the words stick, because each one is tied to something that happened on the screen.
The mentor adapts
Mentors speak slowly, use short sentences, and learn each child's accent. A child who answers in a mix of English and German is understood, and hears the English word back without any fuss.
The mentors are based in India and teach over live video, which is why afternoon times work well for Rostock. Your child is not passed from teacher to teacher; one mentor stays, and soon knows whether your child prefers to be challenged straight away or to warm up with something familiar.
By age
What does a Rostock child build at each age?

Dates as listed for Mecklenburg-Vorpommern in the KMK school holiday overview 2026/2027, dated 9 October 2025.
Classes continue through school holidays unless you pause. Rostock is the largest city in Mecklenburg-Vorpommern, home to 205,307 people on the Destatis count for 31 December 2024, while the Land capital Schwerin has 98,308, in a Land of 1,573,597. Children from Warnemünde, Bad Doberan or Güstrow join the same online groups and share Rostock's holiday dates.
One more date for this month: the Informatik-Biber, a free puzzle contest for grades 3 to 13 that needs no coding, takes place from 9 to 20 November 2026. Pupils enter through their school, so it is worth asking the class teacher.
Milestones
What milestones will my child reach?
Our milestones, each one something your child can show you on screen.
Our five milestones between 6 and 12
Milestone
On screen, your child
Sequencer
Give a sprite five instructions in the right order
Looper
Repeat a set of steps without copying them
Scorekeeper
Keep a score and a high score in a game
Typist
Write a short Python program and fix its first error
Record hunter
Find a record in a real file and explain what "since" means
For parents
The record hunter milestone matters beyond coding: a child who asks "since when?" about a record has learned to read headlines more carefully.
You get a short note every few classes about what was built.
For children
The first try always wins. That does not make it a great record.
When you change where you start, check whether the answer changes too.

Fees
What do coding classes cost for a Rostock child?
There is a monthly fee for eight live classes. We list it in euro, using the European Central Bank reference rate, and take the payment in US dollars; your bank handles the conversion, so the euro amount it books can be marginally different.

Rostock parents ask
Coding classes for kids in Rostock: parents' questions
Are the classes taught in German?
No. We only teach in English. The mentor in India keeps sentences short, says important words twice and quickly tunes in to how your child talks; because every step also happens on the screen, children with little English still manage.
How young can my child start?
At 6. The youngest start with puzzles and Scratch, where blocks are dragged rather than typed. Children usually move to Python at about 9, once reading and typing are comfortable.
When does Informatik start at school in Rostock?
In grade 5. The Gesellschaft für Informatik reports that Mecklenburg-Vorpommern teaches Informatik und Medienbildung at every school type in grades 5 to 10, at least one weekly hour each year. Grundschule, grades 1 to 4, has no Informatik subject.
Why learn coding before grade 5?
Because the school subject only starts in grade 5, and four years is a long wait for a curious child. Children who have already built a few games arrive in grade 5 with something to show and questions to ask, rather than starting from nothing.
When are classes in Rostock time?
Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Rostock families usually pick mid-afternoon or a weekend morning.
What is the Warnemünde records project?
An original lesson we wrote using Deutscher Wetterdienst records from the Rostock-Warnemünde station. Children find the hottest day of each year since 1947, count how often the record was broken, and see that the count changes with the starting year.
Does my child need a computer?
Yes, a laptop or desktop with a keyboard and a headset works well. Very young children can start on a tablet for Scratch, but Python needs a keyboard.
Where are the teachers?
They are in India and join by live video. A 16:20 class in Rostock is at 20:50 on the mentor's clock this winter. One mentor stays with your child for the whole course.
How many children are in each group?
Between fifteen and twenty, all roughly the same age. If you would rather your child learned alone, one-to-one means two weekly classes with only the mentor.
How do we pay?
Once a month. You see the price in euro, worked out with the reference rate of the European Central Bank; the actual charge is in US dollars and your bank turns it into euro, sometimes with a small difference. Booking the trial class needs no card.
