I believe the best 'Montessori' activities for Christmas including baking Christmas treats (always Gingerbread!) and making gifts by hand. We LOVE Christmas themed playdough and Christmas puzzles! Here are a few other ideas to bring some Christmas to your Montessori shelves at home, homeschool or school! 

Above toddler language cards at Montessori and Me. 

What's different Christmas cards by Maria Schavez. 

Christmas Mystery Bag by Maria Schavez. Maria has lots of Montessori inspired Christmas ideas! 

Initial sound work, free printables and lots of other Christmas ideas at Montessori Nature. 

Christmas themed Knobless Cylinder work. I know some teachers use extension ideas like this and others don't. Also at Montessori Nature. Printable here. 

I love this one, Montessori Christmas three part cards + silhouette cards that can be used with the TOOBS Christmas set, which means the child (toddler/preschooler) can match object to picture or object to silhouette. Also at Teachers Pay Teachers, this Christmas matching activity. 

Pincer and fine motor work including dropper and Christmas tree at Cameron Park Montessori. 

This might be a fun one to try at home if you have some shape blocks at You Clever Monkey. 

Tonight I've printed the 'fill in the blanks' and crossword puzzle for my boys from the Christmas Word Wall at Montessori Print Shop (works out just over $2 AUD), I think they'll enjoy it! I hope you've found some useful ideas!
