First Grade Number Strips: This 29-page resource is ready to print and laminate. You can keep the strips in a pouch or punch a hole and clip them together. You can make multiple rings so several students can be working on this center together. If you do not like to laminate, you can print and place into sheet protectors. I like to put them into the plastic 3-prong folders and make several for multiple students to work on at one time.
First Grade Partitioning 2-D Shapes Bundle:
This bundle includes two full-color math centers and 5
recording sheets that could be used for worksheet/homework, etc. You can use these to model how to sort the shapes into categories or use this as a math center. It specifically uses the shapes listed in the TEKS which will support your first grade classroom.
