Start of Lesson: Exploring Numbers in the World Around Us

Introduction: A Curiosity Quest

Welcome, math magicians! Today, we are diving into an exciting adventure of numbers and their amazing powers. To kick off our lesson on Number and Operations in Base Ten (NBT.a), I have a fun challenge for you!

The Great Number Scavenger Hunt

Objective:

In teams, you will go on a scavenger hunt to find various items around the classroom or playground that can be counted in base ten. This hands-on activity will help you connect with the topic and bring math to life!

Instructions:

1. Form Groups: Split into small groups of four or five.
2. Scavenger Hunt Items: Each group is tasked with finding objects that can be grouped by tens. Here are some examples to look for:
   • Pencils
   • Books
   • Crayons
   • Leaves or stones
3. Counting and Recording:
   • Count how many of each item you can find.
   • Organize your items into groups of ten to make it easier to count!
4. Class Presentation: After your hunt, each group will present their findings to the class. Be ready to share how many groups of ten you found and what that tells us about the whole quantity.

Transition to Math Concepts

As you embark on your scavenger hunt, think about how grouping these items helps us understand larger numbers. By the end of our lesson, we will explore how understanding base ten can transform the way we view numbers!

Ready, Set, Go!

Gather your teams, set your timers for 10 minutes, and remember to keep your eyes sharp for those treasures! Let's make some math magic happen!
