Lesson Plan

1Opening (5 min)

Welcome to today's BibleMouse math adventure! Let's review how we add numbers without trading from yesterday's lesson.

💭 Review Question: Can you show me how you add two-digit numbers without moving to the next column?
2Teaching (12 min)

Today we'll learn about trading ones for tens - just like how God helps us exchange small blessings for bigger ones!

📌 Key Talking Points:
  • When we have 10 ones, we can trade them for 1 ten
  • Use base-ten blocks to show how regrouping works
  • Follow the standard algorithm step by step
💬 Discussion Questions:
  • What happens when we have more than 9 in the ones column?
  • How is trading numbers like being a good steward?
3Activity: Regrouping Block Challenge (14 min)
hands-on

Practice addition problems using base-ten blocks, focusing on trading ones for tens

📝 Instructions:
  1. Set up your addition problem with base-ten blocks
  2. Count the total number of ones
  3. If ones total 10 or more, trade 10 ones for 1 ten
  4. Complete the addition problem
🔄 Variations:

Simpler: Use smaller numbers with easier regrouping

Challenge: Create multi-step addition problems requiring multiple trades

4Closing (4 min)

Review key concepts of trading and regrouping

📝 Review Questions:
  • What happens when we have 10 or more ones?
  • How do base-ten blocks help us understand trading?

Coming up: Tomorrow we'll learn about trading tens for hundreds in our BibleMouse math journey!
