Title: Finding Whole-Number Quotients and Remainders with Up to Four-Digit Dividends and One-Digit Divisors

Grade Level: 4th or 5th grade

Objective: - Students will be able to divide whole numbers with up to four digits by one-digit divisors, finding both the quotient and remainder. - Students will understand the concept of division and how it relates to multiplication and subtraction.

Materials: - Whiteboard or blackboard - Markers or chalk - Dividend and divisor flashcards (with numbers up to four digits and one digit, respectively) - Worksheets with division problems - Pencils or pens

Procedure:

1. Introduction (5 minutes):
   • Begin the lesson by asking students if they know what division is and how it is related to multiplication and subtraction.
   • Write the terms “dividend,” “divisor,” “quotient,” and “remainder” on the board, and briefly explain their meanings.
   • Tell students that today, they will learn how to find whole-number quotients and remainders when dividing numbers with up to four digits by one-digit divisors.
2. Whole-Class Instruction (10 minutes):
   • Demonstrate the process of dividing a four-digit number by a one-digit number on the board, step by step.
   • Emphasize the importance of starting with the largest place value and working towards the smallest.
   • Show how to subtract the product of the divisor and quotient from the dividend to find the remainder.
   • Provide examples and encourage students to ask questions if they need clarification.
3. Guided Practice (15 minutes):
   • Distribute dividend and divisor flashcards to pairs of students.
   • Instruct students to take turns being the “divider” and the “dividend.”
   • The divider should divide the dividend, finding the quotient and remainder, while the other student checks their work.
   • Circulate the classroom, providing assistance and guidance as needed.
4. Independent Practice (15 minutes):
   • Hand out worksheets with division problems involving four-digit dividends and one-digit divisors.
   • Instruct students to solve the problems independently, showing their work and writing both the quotient and remainder.
   • Encourage students to use the strategies discussed during the whole-class instruction.
   • Monitor the class, offering support and answering questions.
5. Review and Closure (5 minutes):
   • Collect the worksheets and review a few problems as a class, allowing students to share their answers and methods.
   • Ask students to reflect on what they have learned about division and how it relates to multiplication and subtraction.
   • Summarize the key points of the lesson and address any remaining questions or concerns.

Extensions: - For advanced students, provide additional division problems with larger dividends and divisors. - Introduce word problems that require students to apply their division skills in real-life scenarios. - Encourage students to explore long division with decimals or fractions, if appropriate for their grade level.

Assessment: - Monitor students’ progress during the guided and independent practice, providing feedback and assistance as needed. - Collect and review the completed worksheets to assess students’ understanding of finding whole-number quotients and remainders. - Use additional formative assessments, such as oral questioning or exit tickets, to gauge individual comprehension.
