I love Doddle Bugs Teaching! I bought her Christmas Centers (part 1 and part 2) and used them in my classroom before the start of vacation. My students loved them and seeing how engaged they were was one of the main reasons I decided to start my own blog (which is to hold myself accountable for making materials that are more child-friendly and exciting).
She recently posted her Winter Centers and I loved them so much that I actually bought most of the same clip art to make my own (unfortunately I didn't feel most of her centers would be appropriate for the current needs of my students, but hopefully they are perfect for your students). If you aren't familiar with her blog or her beautiful products, click the button above to check it out.
And feel free to leave me a comment sharing a link to one of your favorite blogs!
