Free 5th Grade Using Area Model To Divide Lesson Plan

Topic: Using Area model to divide

Objectives & Outcomes

• Understand how to divide using area model
• Be able to solve division problems using area model

Materials

• Pencils
• Rulers
• Calculator (optional)

Warm-up

• Review the meaning of division and the symbol used to represent it (÷).
• Ask the students to give examples of divisions they have seen or done in the past, such as 8 ÷ 2 = 4, or 2 ÷ 3 = 0.67.
• Ask the students if they can think of any situations where they might have to divide numbers in the future.

Direct Instruction

• Introduce the concept of dividing using an area model.
• Show a square piece of paper and a ruler. Ask the students to imagine that the square piece of paper represents the number being divided, and the ruler represents the divisor (the number being divided by).
• Explain that if we fold the square paper in half, and then in half again, we have created four equal sections. These sections represent the number being divided into equal parts.
• Then, using the ruler, we can measure the area of each section and use that to find the result of the division. For example, if the divisor is 4 and the area of each section is 0.25, then the result of the division is 0.25 ÷ 0.25 = 1.
• Repeat with a different number and divisor to reinforce the concept.

Guided Practice

• Have the students work in pairs. Give each pair a square piece of paper and a ruler.
• Have the students first use the ruler to measure the area of the square paper. Then, have them use this value to calculate the result of a division problem, such as 4 ÷ 0.25.
• Have the students check their answers with a calculator, and discuss possible reasons for any differences.

Independent Practice

• Have the students work in small groups. Give each group a sheet of rectangular paper and a ruler.
• Have the students first use the ruler to measure the area of the rectangular paper. Then, have them use this value to calculate the result of a division problem, such as 4 ÷ 0.25.
• Have the groups share their results with the class and discuss any differences in the solutions.

Closure

• Review the steps for dividing numbers using the area model.
• Ask the students to share any interesting or surprising results they found when practicing division in class.

Assessment

• Observe the students during the independent practice activity and provide feedback on their ability to use the area model to divide numbers.
• Collect and grade the students' work, looking for correct use of the area model and accurate results.
