⭐️ Hands-On Number Sense Activities for Whole Group, Small Group, and Centers

These activities were created for hands-on practice with number sense concepts!

I included activities to use during:

• Small Group Time – students get guided practice at the teacher table during math rotations
• Whole Group – I included activities that are perfect for whole group review during or at the end of your unit
• Math Centers - I love re-using activities we have already done together at teacher table because students are able to complete them independently!

NOTE: At the beginning of the year, if you have not begun your math rotations, these activities can be done whole group or in partners! I give more directions on how to do this in the Guided Math Launch Guide!

• I Am a Mathematician Writing Activity

For each activity, I included teacher notes that give ideas for using the activity in your classroom!

Math Mats are my favorite for no-prep activities. These activities are perfect for centers or small group work. They are designed to be hands-on and interactive, allowing students to apply the concepts they have learned in a fun and engaging way.

To use: just slide them into dry erase pockets and add manipulatives for hands-on practice!

⭐️ Anchor Charts and Mini Posters 

These posters are perfect for classroom display and serve as a visual reminder of the key concepts covered in the unit. They include colorful graphics and clear explanations of concepts. Create a math reference wall to add to throughout your number sense unit.

I also love using the included mini posters to make vocabulary rings for students to access during small group and math centers. 

And I give each of my students the individual Number Sense Vocabulary Sheet to keep in their math folders for easy reference!

⭐️ Number Sense Worksheets

This unit includes 20 worksheets for independent practice of the skills taught during the mini lessons! Perfect for math centers, independent work, and morning work.

Exit Slips:

• These are designed to be quick check-in used throughout your unit for formative assessment.
• At the end of your lesson, give an exit slip to each student to complete. Collect and use the data to guide the next days small group instruction.
