Coordinate Geometry

Grade 9 Math Homework that will put a smile on your face....

A Mathematics Teacher shared some of her students’ mathematics homework just before Spring Break: “I am very proud of my grade 9 students’ work. We worked on coordinate geometry before Spring Break and they had to create their own pictures using linear or quadratic functions. Enjoy!”

Primary Students Spread Hope

Children worldwide are drawing rainbows to spread hope at a time when positive energy is needed most. H.I.S. Primary students have produced rainbow art work and have displayed it at home or in windows facing the street for passers by to enjoy.

A word from a mom: Jacinta did rainbows for all our neighbours and for police officers who stand in front our place and was SO happy with it. She even received some “Danke” cards in return.

Support Keno's and Tiago's efforts to produce protective masks

Here is a message from H.I.S. Graduates Keno and Tiago (Classes of 2014 and 2015) to the H.I.S. community:

We hope you are doing well in these very challenging and uncertain times and that H.I.S. is coping with the current situation. I am sorry for the IB class that their exams have fallen through. Keno is luckily done with his studies, but mine have been interrupted and I am still uncertain of how they will continue.

Meanwhile I have returned to the safety of Heidelberg and my parents’ house, and am trying to stay on top of my studies and research.

Keno and I decided to try and do more than just stay at home. We want to help with the current crisis – that we expect is still going to get worse before it gets better.

Over the last couple of months, Keno and I have been working on building a small start-up company called R3ality Design specialising in 3D printing solutions for research and home improvement. We have been producing parts for researchers at my university. During the current crisis however, we stopped all other production and have dedicated our efforts to maximising our 2 printers to produce face shields for health care professionals 24/7.

Our latest batch of 15 masks was picked up this morning by the University Clinic Heidelberg who were incredibly grateful, and will be coming by every couple of days for further batches. In between we are bringing masks to our local doctor (Hausarzt) who is in dire need of protective equipment for himself and his staff. We are further putting masks to the side to send to my fellow doctors back in Rotterdam.

The plans for the mask were made available online. Keno and I have been tirelessly calling producers of plastic visors, of plastic filaments for the printers, of rubber headbands and even of zip-lock bag products. While some of these producers replied and generously donated some items, our supplies are going to run out due to the high demand.

At H.I.S. we were always taught the importance of community and I can feel this through the enthusiasm behind the H.I.S. blog (With your current a “blog a day”). In line with the school’s dedication to making a difference, we were wondering if H.I.S. would like to support our efforts with producing protective equipment for the hospitals and clinics in Heidelberg.

We would be grateful for any donations:

Keno and I are currently spreading our message via social media (LinkedIn, Facebook, Twitter (, Instagram ( and are dedicated to expressing our sincere thanks to all the companies and associations who are supporting this project and the health care professionals.

Take care, stay safe and healthy.

Tiago and Keno

Active at a distance - PE

There is no stopping H.I.S. students getting out for their daily exercise.

Students in the Primary and Secondary school have been doing what they can to keep fit while following the government’s advice on social distancing. Staying fit and healthy is so important for your well-being and will help you to learn at home or at school.

Keep sending your photos to Mr Knowles in the MYP and post them on Seesaw in the Primary School for Mr Raw and Mrs Macdonald.

Greetings from Canada

For those of you who never met Lori, but have wondered whom the Lori-Novak-Boulevard is named after: Lori was the H.I.S. Admissions Counsellor for many years. Together with her husband, Helmut, she moved to Vancouver Island, Canada, after her retirement. So good to hear from you, Lori!
We are of course practising physical distancing here as well, but my husband and I are keeping very busy with various redecorating projects in our new home, “digging in the dirt” of our garden which is beginning to burst into blooms, and enjoying long walks amidst the gorgeous coastal scenery of Vancouver Island – a good place to weather this storm!
My thoughts are with the H.I.S. community, and I hope you are all coping with the challenges of these strange times.
Take heart and stay well! ❤

Keepy Uppy Challenge

There are many ways to add a work out to your daily schedule…

You can set up a fitness studio in your basement, go for a run or a walk, or you can pick up your bike. If you can spare one role of toilet paper, then there is another way: You can take part in the first H.I.S. Toilet Paper Keepy Uppy Challenge.

Thank you, Mr. Knowles, for starting the challenge. Mr Knowles managed 20 – can you beat him?


Have an active day!

Schüler machen Zeitung! H.I.S. Junior Journalists

In November and December 2019 the grade 9/10 German Language and Literature class took part in the annual project “Schüler machen Zeitung” organised by the local Rhein Neckar Zeitung.
The project entailed a daily RNZ subscription and a newspaper article writing competition. Each year several hundred students from schools in the Heidelberg area participate in this project. Every student writes an article about a topic of personal interest. The best articles are chosen and published by the RNZ.
Finally, last week, in a separate “Sonderbeilage” of the RNZ, the best 40 student articles were published and we are very proud that you can find 4 articles of H.I.S. students among them.
Well done Anton, Elli, Eshal, Franklin, and Jooke!
Elli and Jooke:
A big thank you to Frau Kress for supporting the students and this project!

Online Music

The G6 German language Acquisition class started to vividly present their daily routines on Powerpoint via Zoom last week.

Brianna and Frau Stricker introduced their dogs and Pablo even gave an impromptu concert on his French Horn! Bravo, Pablo! Let’s hope we can soon go back to our usual routines and in the meantime, stay connected and make the best of the new learning opportunities we have!
