🎯 What You'll Learn

Learning Objectives

1

Understand that bar graph squares can represent more than one unit

2

Read and interpret scaled bar graphs accurately

3

Develop patience and attention to detail in mathematical thinking

📖 Scripture Connection

Proverbs 16:16

“How much better is getting wisdom than gold! And getting understanding is more desirable than silver.”

— Proverbs 16:16 (WEB)

Just as a scaled graph helps us understand data more precisely, wisdom helps us understand life more deeply

Lesson Plan

1Opening (3 min)

Review previous day's bar graph skills

💭 Review Question: Can you remember how we made a bar graph yesterday?
2Teaching (10 min)

Introducing scaled bar graphs where each square represents multiple units

📌 Key Talking Points:
  • Sometimes one square can represent 2 or 5 or 10 things
  • This helps us show bigger numbers on our graph
  • We'll count carefully to read the correct total
💬 Discussion Questions:
  • Why might we want to use a scale?
  • How can we tell what each square represents?

Create a scaled bar graph showing animal heights

📝 Instructions:
  1. Draw graph with scale of 2 units per square
  2. List animals: Mouse, Cat, Dog, Horse
  3. Measure and plot animal heights
  4. Color and label carefully
🔄 Variations:

Simpler: Use pre-drawn graph with 2-unit scale

Challenge: Create own scale with 5 or 10 units per square

4Closing (3 min)

Review scaled graph concepts

📝 Review Questions:
  • What does each square represent?
  • How do we count total units?

Coming up: Tomorrow we'll survey classmates and create a group graph!
