7th Grade Rational Number Lesson Plan Example (Math)

Topic: Rational number

Objectives & Outcomes

• Students will be able to identify a rational number and write it as a/b such that b ≠ 0.
• Students will be able to add, subtract, multiply, and divide rational numbers.

Materials

• Calculators
• Worksheets with examples of rational numbers

Warm-up

• Show the students a picture of a rational number and ask them to identify it as a rational number.
• Ask the students to give examples of rational numbers.
• Write the numbers 1, 2, 3, and 4 on the board and ask the students to identify which numbers are rational and which are not.
• Write the numbers 5, 6, and 7 on the board and ask the students to identify which numbers are rational and which are not.

Direct Instruction

• Introduce the concept of a rational number as a number that can be written as a/b such that b is not equal to zero.
• Show the students some examples of rational numbers, such as 4/5, -3/4, and 3/4.
• Explain the significance of writing a number as a/b, where a is the numerator and b is the denominator.
• Explain the significance of b not being equal to zero.
• Demonstrate how to write a number as a/b, where a is the numerator and b is the denominator, using a calculator.

Guided Practice

• Have the students work in pairs to practice writing rational numbers using a calculator.

Have them start with a number such as 5 and use the calculator to find the numerator and denominator.

• Have the students check their answers by using the calculator to verify that their numerator and denominator produce a rational number.

Independent Practice

• Have the students create a worksheet that includes several problems involving writing a rational number as a/b.
• Have them use the steps outlined above to solve the problems and check their answers using a calculator.

Closure

• Review the steps for writing a rational number as a/b.
• Ask the students to share any challenges they faced and how they were able to overcome them.

Assessment

• Observe the students during the guided and independent practice activities to assess their understanding of the concept.
• Collect and review their written work to assess their ability to write rational numbers as a/b.
