I've been obsessing over flip books lately! I've created at least 8 new flip books in the past 2 months and this quadrilateral flip book is one of my favorites.
The hierarchy of 2D shapes (quadrilaterals specifically) always seem to confuse my students. They're pretty good with understanding characteristics of individual shapes but they have a hard time seeing how they all fit together into a hierarchy of similar attributes.
I have found that this book also helps students keep track of all of their learning in one place. Sometimes they just need something easy to refer to. I love flip books because they're great at keeping everything in one spot for my students, making it more likely that students will review and access their prior learning.
The students love being able to write on the shapes in this book. We measure each shapes sides for practice with rulers. We also measure all of the angles in each shape as an exploration into shape attributes as well as for additional practice with protractors.
These flip books are really engaging and the students love working in them!
