🎯 What You'll Learn

Learning Objectives

1

Add one-digit numbers to two-digit numbers without regrouping

2

Understand place value concepts

3

Develop confidence in mathematical problem-solving

📖 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 step by step, we build wisdom through careful learning and practice

Lesson Plan

1Opening (5 min)

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

💭 Review Question: Can you show me how we add numbers using our base-ten blocks?
2Teaching (10 min)

Today we'll learn how to add one-digit numbers to two-digit numbers without changing the tens place.

📌 Key Talking Points:
  • Look at the number 34. This has 3 tens and 4 ones.
  • When we add 5 to 34, we'll only change the ones place.
  • 34 + 5 becomes 39
💬 Discussion Questions:
  • What happens to the tens place when we add a small number?
  • Can you predict what 42 + 6 will be?

Use base-ten blocks to solve addition problems and find hidden 'treasures'

📝 Instructions:
  1. Arrange base-ten blocks to show the two-digit number
  2. Add the one-digit number by placing additional ones
  3. Count the total blocks to find your answer
  4. Mark correct answers on your BibleMouse worksheet
🔄 Variations:

Simpler: Use smaller numbers (20-30 range)

Challenge: Add multiple one-digit numbers to two-digit numbers

4Closing (3 min)

Let's review what we learned about adding numbers today!

📝 Review Questions:
  • What happens to the tens place when we add a small number?
  • Can you show me how to add 36 + 4?

Coming up: Tomorrow we'll learn about adding numbers that require 'regrouping' - moving numbers between tens and ones places
