Grade 5 our launching their new unit of inquiry Sharing the Planet this week!

SOLO and Word Vocabulary List will be on the Seisen website soon - watch this space. 

It is important to note that in alignment with the Enhanced PYP, students may develop the SOLO taxonomy by co-constructing this with their teachers. This is to provide students with agency - choice, voice and ownership throughout the process of their learning. Therefore the SOLO co-constructed by students may look slightly different this one. This learning progression and vocabulary list is developed so you can support your daughter's learning at home.

How can I use the SOLO at home?

On the SOLO you will see two sections, one with inquiry questions to guide students learning through the different stages as they move from a shallow understanding of the lines of inquiry to a more deeper understanding. The possible assessment criteria are learning outcomes - learning outcomes are statements that describe the knowledge or skills we aim for students to acquire as a result of their engagement with the unit of inquiry. Inquiry is the leading pedagogy within the Primary Years Programme. Students are at different developmental stages and therefore may reach different levels of proficiency with knowledge and skills. Additionally you will see "possible questions to discuss". These are teacher guided questions that help to direct the unit of inquiry. You may wish to use these questions to begin a conversation with your chid about their unit of inquiry at home. 

How can I use the Vocabulary Lists at home? (These are on Page 2 after the SOLO)

The Vocabulary Lists are a guide for the possible vocabulary that may be explored throughout the unit of inquiry. It is encouraged that you explain and explore the words within this list with your child in their mother tongue. Perhaps you may talk about the concept of some of the words in English and also in your home language in order to deepen their understanding of them. There are blank spaces on the Word Vocabulary Lists where you and your child might generate more words that connect to the unit of inquiry. Please feel free to add them to the list, either in English or your mother tongue language. Ask your daughter to share these new words that have come up in conversations at home with their teacher, to build the connection between discussions at home and school. 

If you have any experience or expertise with the content of these units of inquiry, we would love to hear from you! We are extremely excited to have our community content with the unit of inquiry through sharing their knowledge, experiences or passions in these areas with us. 

Additionally, if you see your child taking action as a result of their learning at school, we would LOVE to hear about it! As action is often taken outside of the learning environment, we often don't know about these opportunities that you as parents are witness to, even a short email telling us about something your child did or said at home as a result of their learning helps us know how the PYP is supporting the development of life long learners that take action!

Please contact our PYP Coordinator ( or your daughter's homeroom teacher.
