Lesson Plan

1Opening (3 min)

Welcome to today's BibleMouse math adventure! Let's review how we traded ones yesterday when they got too big.

💭 Review Question: What happens when we have more than 9 ones?
2Teaching (10 min)

Today we'll practice regrouping with our base-ten blocks, just like building something amazing requires careful steps.

📌 Key Talking Points:
  • When ones reach 10, we trade for a ten
  • Base-ten blocks help us see this process
  • Regrouping is like organizing a big project
💬 Discussion Questions:
  • What do you think happens when we have too many ones?
  • How can we make our math neat and organized?
