I have been working all year on establishing interactive notebooks with my math classes. I'll be adding resources here periodically as I find them so I can make my notebook even better for my kiddos.
Interactive Notebook examples for multiple subjects
Runde's Room Interactive Math Journals
Create Teach Share
Fourth Grade Flipper: This one is for Language Arts but still a good example
Education to the Core
Fourth Grade Team Interactive Math Notebook for Fractions (and a bit of decimals)
Carson Dellosa I bought these books for both 4th and 5th grade at my local education store and they're great so far!!!
