Lesson Plan: Introducing Dividing Decimals
Grade Level: 6
Subject: Mathematics
Topic: Divide Decimals
Lesson Part: New Topic
Objective:
Students will understand the concept of dividing decimals and learn strategies to effectively divide decimal numbers.
Materials Needed:
- Whiteboard and markers
- Worksheets with practice problems
- Base ten blocks or decimal grids
- Real-life examples of dividing decimals (e.g., recipes, budgeting)
- Interactive quiz platform (e.g., Kahoot, Quizizz)
Introduction (10 minutes)
-
Engage Students:
Begin with a brief discussion about where students encounter decimals in real life. Ask questions like:
- "When do you use decimals in shopping or cooking?"
- "Can someone give an example of a decimal in a budget?"
-
Introduce the Topic:
Explain that today’s lesson will focus on dividing decimals. Relate it to their previous knowledge of dividing whole numbers and how decimals can be involved in various contexts.
Direct Instruction (15 minutes)
-
Explain the Concept:
- Explain Division of Whole Numbers: Recap how to divide whole numbers. Use a simple example like 12 ÷ 3 = 4.
- Transition to Decimals: Introduce the division of decimals by explaining that dividing decimals follows the same principles. Use examples like 4.5 ÷ 1.5 to illustrate this idea.
-
Demonstrate Steps:
Walk students through the steps of dividing decimals:
- Step 1: Move the decimal point in the divisor (the number you're dividing by) to the right until it’s a whole number.
- Step 2: Move the decimal point in the dividend (the number you are dividing) the same number of places.
- Step 3: Divide as if they were whole numbers.
- Step 4: Place the decimal point in the quotient (the answer) directly above where it now appears in the dividend.
Guided Practice (10 minutes)
-
Example Problems:
Write a couple of division problems on the board:
-
Group Activity:
Have students work in pairs to solve similar problems using base ten blocks or decimal grids. Encourage them to visualize the division process.
Independent Practice (15 minutes)
- Worksheet Activity:
Distribute a worksheet with various problems that involve dividing decimals. Include:
- Basic problems (e.g., 5.85 ÷ 0.3)
- Real-life application: (e.g., “If 4.5 meters of fabric costs $9, how much does 1 meter cost?”)
Closure (5 minutes)
-
Review Key Points:
Recap the steps for dividing decimals and highlight the importance of moving decimal points correctly.
-
Exit Ticket:
Ask each student to write down one newly learned strategy for dividing decimals on a small piece of paper or virtual platform.
Assessment:
- Collect the worksheet for grading.
- Use the exit ticket responses as a quick informal assessment to evaluate understanding.
Extensions and Variations
- Real-World Applications: Bring in real-life situations where students might need to divide decimals (e.g., currency conversion, measuring ingredients).
- Technology Integration: Encourage students to use online math games that focus on dividing decimals to reinforce their skills.
This exciting lesson approach blends practical engagement with foundational math, making learning to divide decimals both fun and relevant for sixth graders!
