Learning Objectives

1

Represent simple word problems using mathematical equations

2

Use a symbol (like □ or x) to represent an unknown number

3

Develop problem-solving skills with a heart of patience and curiosity

📖 Scripture Connection

Proverbs 2:2

“So that you incline your ear to wisdom, and apply your heart to understanding;”

— Proverbs 2:2 (WEB)

Just as we seek understanding in God's Word, we seek to understand mathematical problems by carefully listening and applying our minds

Lesson Plan

1Opening (3 min)

Review yesterday's lesson about finding missing numbers in equations

💭 Review Question: Can you remember how we used a special symbol to show a number we didn't know yet?
2Teaching (10 min)

Introduce how stories can become mathematical equations

📌 Key Talking Points:
  • An equation is like a balanced scale where both sides are equal
  • We can use □ or x to represent an unknown number
  • Word problems tell us a story that we can turn into a math sentence
💬 Discussion Questions:
  • What do you think a symbol like □ might mean in a math problem?
  • How can we tell what number might go in that space?
3Activity: Story to Equation Challenge (12 min)
discussion

Transform simple word problems into mathematical equations

📝 Instructions:
