After examining our central idea and lines of equiry, we did a quick 10 minute pre-assessment to find out what we already know about the lines of enquiry.
We shared our understandings as a whole class discussion with more of a focus on ways we use the rounding strategy in our daily lives so that we all gained a sense of the reason we should enquire into the strategy.
Once children know there is a practical purpose to learning something in maths, their engagement increases a lot.
Some samples:
Based upon some of the ideas some had of how we use the rounding strategy in our daily lives, I created a google doc activity that showed different ways we use rounding. To help connect, I used student names and everything based from Lausanne.
The Google doc questions:

As we do our enquiries, the children are encouraged to record what they have learnt during their learning time. Sometimes, if they are too absorbed in the activities, I give them 5 or 10 minutes at the end to reflect. We regularly discuss the importance of reflecting and how it helps to deepen our understanding.
A beginning example:
This is the feedback they will receive at the end of their enquiries using PYP Learner Profile attributes & attitudes:
