🎯 What You'll Learn

Learning Objectives

1

Understand how to regroup when subtracting in the ones place

2

Use base-ten blocks to demonstrate borrowing from tens place

3

Develop patience and precision in mathematical problem-solving

📖 Scripture Connection

Proverbs 13:11

“Wealth gained dishonestly dwindles away, but he who gathers by labor increases it.”

— Proverbs 13:11 (WEB)

Just as careful accounting matters in biblical stewardship, precise mathematical regrouping requires careful attention and step-by-step diligence

📦 Materials Needed

  • Base-ten blocks
  • Subtraction mat
  • Pencil
  • Worksheet
  • BibleMouse Math Workbook
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Review previous day's subtraction without borrowing, introduce concept of 'trading' in math

💭 Review Question: What happens when the top number is smaller in the ones place?
2Teaching (12 min)

Demonstrate borrowing using base-ten blocks, showing how 1 ten can be exchanged for 10 ones

📌 Key Talking Points:
  • When we can't subtract in the ones place, we need to borrow
  • One ten is equal to ten ones
  • Carefully track each step in the regrouping process
💬 Discussion Questions:
  • What do you think happens when we 'borrow' in math?
  • How is borrowing like sharing resources?
3Activity: Borrowing Block Challenge (14 min)
hands-on

Practice subtraction problems using base-ten blocks, demonstrating regrouping

📝 Instructions:
