Objective

By the end of this lesson, you will be able to divide numbers using different strategies and understand the concept of division.

Materials and Prep

• Pencil
• Blank paper
• Ruler

Before starting this lesson, make sure you have a good understanding of basic multiplication and subtraction.

Activities

1. Activity 1: Introduction to Division

   Draw a rectangle on the paper and divide it into equal parts using the ruler. Explain that division is about splitting something into equal groups.

2. Activity 2: Division with Manipulatives

   Use small objects like buttons or beads to represent numbers. For example, if you have 12 buttons, divide them into groups of 3. Count how many groups you have and how many buttons are in each group.

3. Activity 3: Division with Number Lines

   Draw a number line on the paper and choose a number to divide. For example, if you want to divide 16 by 4, start at 0 and jump in increments of 4 until you reach 16. Count how many jumps you made.

4. Activity 4: Division Word Problems

   Create word problems related to division and solve them together. For example, "There are 20 cookies and 4 friends. How many cookies can each friend have?" Use drawings or objects to help visualize the problem.

Fourth Grade Talking Points

• "Number lines can also be used to solve division problems."
• "Word problems can be solved using division."
• "Division is the opposite of multiplication. It helps us find out how many groups or how many items are in each group."
