🎯 What You'll Learn

Learning Objectives

1

Solve simple addition word problems using manipulatives

2

Understand 'join' problems where quantities are added together

3

Develop problem-solving confidence and mathematical thinking

📖 Scripture Connection

Proverbs 4:7

“Wisdom is supreme. Get wisdom. Yes, though it costs all your possessions, get understanding.”

— Proverbs 4:7 (WEB)

Just as we build understanding in math by adding knowledge step by step, we can build wisdom by carefully learning and growing

Lesson Plan

1Opening (5 min)

Welcome to today's BibleMouse math adventure! Let's review what we learned about adding numbers yesterday.

💭 Review Question: Can you show me how you would add 24 + 15 using base-ten blocks?
2Teaching (10 min)

Today we'll explore 'join' problems - where we start with one amount and add more to it.

📌 Key Talking Points:
  • In a join problem, we begin with a starting number
  • Something gets added to that number
  • We find the total by adding together
💬 Discussion Questions:
  • What does 'join' mean in math?
  • How can we use objects to help us solve these problems?

Use manipulatives to solve join word problems

📝 Instructions:
  1. Start with a small group of counters
  2. Draw a problem card from the BibleMouse word problem set
  3. Use counters to physically represent the problem
  4. Solve the addition problem step by step
  5. Check your answer using the hundreds chart
🔄 Variations:

Simpler: Use fewer counters and smaller numbers

Challenge: Create your own word problems to solve
