Lesson Plan

1Opening (5 min)

Welcome to today's BibleMouse math adventure! Let's review how we've been learning to add numbers by breaking them into parts.

💭 Review Question: Can you show me how we separated 34 into 30 and 4 yesterday?

Today, we'll learn a special way to add two-digit numbers by breaking them into tens and ones. It's like solving a puzzle!

📌 Key Talking Points:
  • Look at the number 34 - it has 3 tens and 4 ones
  • When we add 34 + 23, we'll first add the tens: 30 + 20 = 50
  • Then we'll add the ones: 4 + 3 = 7
  • Finally, we combine: 50 + 7 = 57
💬 Discussion Questions:
  • What do you notice about how we broke the numbers?
  • Can you see how this makes adding easier?
