Here’s a great activity from Motherwell Montessori for elementary-aged children or advanced preschoolers. It can be used to introduce Thanksgiving nouns or to work with articles along with the Thanksgiving nouns.
The activity is designed to sort Thanksgiving nouns that are person, place, or thing. Motherwell Montessori even provides a free download. The activity is simple to prepare and only requires paper, printer, cutter, and lamination (optional). For a seasonal activity for home use, you could print the activity on thick, glossy photo paper and skip the lamination.
You might want to introduce the activity Nouns: Person, Place, & Thing from Homemade Montessori before the seasonal nouns.
If you’re ready to introduce articles, here are some introductory activities from Info Montessori: The Article.
