🎯 What You'll Learn

Learning Objectives

1

Understand how to express arrays as repeated addition

2

Count rows and columns to create addition equations

3

Develop appreciation for God's orderly mathematical design

📖 Scripture Connection

1 Corinthians 14:40

“Let all things be done decently and in order.”

— 1 Corinthians 14:40 (WEB)

Arrays demonstrate mathematical order, reflecting God's systematic design in creation

📦 Materials Needed

  • Grid paper
  • Colored pencils
  • Square tiles or counters
  • Pencil
  • BibleMouse Grade 2 Math Worksheet
📚 Step-by-Step

Lesson Plan

1Opening (3 min)

Quickly review yesterday's array drawing lesson, showing how today we'll turn those drawings into math equations

💭 Review Question: Can you show me the array you drew yesterday?
2Teaching (10 min)

Demonstrate how rows in an array can be written as repeated addition

📌 Key Talking Points:
  • An array with 3 rows of 4 is the same as 4 + 4 + 4
  • We can count our rows or columns to make our equation
  • Just like God creates things with purpose, math has a beautiful order
💬 Discussion Questions:
  • How might we count the total in this array?
  • What happens if we switch our rows and columns?
