Inspired by NaganoSarah's post.
Save them as images (they're already grouped objects and can still be edited) and upload them as a background on a jamboard based on the unit in question. (If available in this PPT)
NO MORE PRINTING!!!
The powerpoint has different slides for different lessons, organized by grade and unit lessons.
Add the boat image as an interactive object.
I personally use two slides in the jamboard, one for the student and another for their partner. Make sure to create an assignment so each student has their own copy rather than simply sharing on the classroom.
(P.S. I have added more slides for 1st and 3rd graders)
